10 Best California King Mattresses

How We Chose the Best California King Beds

At Sleep Advisor, our mattress reviews are based on findings from in-person tests that give us a genuine understanding of how the mattress feels and performs. We look at features valuable to consumers, such as temperature control, bounce, edge support, and motion isolation.

We also evaluate mattress performance for back, side, and stomach sleeping. Lying in different positions lets us know how supportive the bed is and whether it effectively relieves pressure.

We then take all the information we’ve gathered to rate the bed in specific categories. These results allow us to help our readers find the right mattress for their needs.

What We Look for in a California King Mattress

Edge Support

Edge support is important to many people, including couples, who are more likely to get a California King bed. Stronger edges allow couples to comfortably spread out, and we look for this in California King beds in particular because they’re slightly more narrow than traditional King sizes.

We look for whether the bed has high-density foam or reinforced coils along the sides, and we also consider the feedback from our mattress testers, who evaluate how the sides hold up while sitting and lying down. 

Durable Construction

A durable construction is important to us in a California King for two reasons. First, this size is more expensive because it’s so much bigger than, say, a Twin or Full. So, you want to know that your investment will last you a while. Second, good durability is important because two people will likely share the bed so you want something that will accommodate the extra weight of a second person without causing early sagging.

For durability, we look at whether it’s equipped with dense foams and/or strong coils, how supportive it is in testing, and the overall appearance of the mattress. 

Value for the Price

A California King bed is the largest (standard) mattress size, so it’s expected to be the most expensive as well. However, you’re getting all that extra space, which in my opinion, is great value for money. 

The price of Cali King beds varies depending on the brand, materials, and overall quality of performance. In most cases, it ranges between $1,399 and $2,666, with the average price being $1,982. We compare prices of our top California King mattresses in a table further below, so you can check the cost of each specific model. 

Even though these beds cost more because of their size, we want to make sure the mattresses we choose for this list are worth that price through great performance in testing, quality features, a good trial and warranty, and longevity. The average price of all the beds you’ll see below is about $2,065.

Why the Helix Midnight Earned Best California King Mattress Overall

If you’re shopping for a California king bed and you value bounce, support, and affordability, the Helix Midnight is a wonderful choice. 

My fellow Lead Product Tester, Loren, found that it also isolated motion surprisingly well, keeping partners from feeling each other’s movements across the mattress’s surface. “But it also has decent responsiveness,” she reported, “so it’s good for sound sleep and sex.” 

It’s not for every kind of sleeper—stomach sleepers look elsewhere—but given its well-balanced construction and budget-friendly price, it’s hard not to put it at the front of the pack. 

Testing Soundbite

“So bottom line, Helix seems to be pretty much a crowd pleaser. If she were in high school, she would be prom queen now.”

Loren Bullock, Former Lead Product Tester

What’s the Helix Midnight Made Of? 

The Helix Midnight has six total layers if you include its top cover. It stands 11.5 inches tall.

Dig Into the Mattress Construction

A closer look at the Helix Midnight mattress construction

  • Layer 1 – Top Cover. A slightly stretchy and soft top cover comes standard with the Midnight. For an additional fee, you can swap it for a GlacioTex™ Cooling Cover.
  • Layer 2 – Memory Plus Foam. Helix’s branded take on memory foam. It molds to the contours of your body and relieves pressure from taxed joints. 
  • Layer 3 – Helix Responsive Foam. A bouncy foam that reshapes quickly when you move around on top of it. 
  • Layer 4 – Helix Responsive Foam. A firmer version of the prior foam serves as the transition layer between the comfort foams above and the coils below. 
  • Layer 5 – Coil Unit. Individually wrapped coils make up the primary support layer of the bed. They’re reinforced on the long edges to help with edge support. 
  • Layer 6 – DuraDense Foam. A thick foam base for stability. 

Customer Reviews of the Helix Midnight

The Helix Midnight has over 6,500 reviews on Helix’s website, scoring at 4.5 out of 5. Users on Reddit’s r/Mattress page express worries over heating, with one redditor (u/BrandonR_24) saying, “I love the comfort of it but if I’m sweating in January I can’t imagine what it’d be like in June.” Otherwise, many say they had a “great experience with Helix and their customer service” (u/positmatt), but warn against making a decision until you’ve broken the bed in.

Cons of the Nectar Mattress

Why the Nectar Earned Best Memory Foam California King Mattress

The Nectar is well-rounded, well-priced, and a memory foam staple of the online mattress world. It’s rare to find such a reputable California King for less than $1,500 (or even less than that, with sales), and the Nectar comes with stellar policies as well. 

Many people who need a California King mattress share the bed, and Nectar’s all-foam construction makes it a motion-isolation champion. Its medium-firm feel also balances pressure relief with base support, so you should feel cushioned but not swallowed by the bed. 

Testing Soundbite

“Foam is a very reactive, bouncy material. Really no surprise the Nectar is so good at staying responsive. So even as you move around the beds not making it difficult to do so. Pressure relief is a must for side sleepers or if you have joint issues. There’s plenty of cushioning around the hips and shoulders, thanks to those memory foam layers.”

Julia Forbes, Sleep Advisor Mattress Tester

What’s the Nectar Made Of? 

The Nectar is 12 inches high and constructed with three distinct foam layers.

Dig Into the Layers

  • Layer 1 – Top Cover. Polyethylene fibers in this upper cover help to draw excess heat away from you. 
  • Layer 2 – Memory Foam (1 inches). Memory foam molds around your body to relieve pressure. 
  • Layer 3 – Dynamic Response Foam (2 inches). A bouncier, more supportive foam layer than the one above it. 
  • Layer 4 – ActiveSupport Foam (8 inches). The base of the mattress ensures longevity and a strong foundation.
  • Layer 5 – Lower Cover. This polyester cover keeps the layers contained.

Customer Reviews of the Nectar

With thousands of reviews on Nectar’s website, the Nectar mattress has an average 4.8 out of 5 stars. On the aptly named r/BuyItForLife subreddit, a longtime Nectar user (u/Interesting-Dot4963) outlined their experience with the mattress: “it is so comfortable but it does feel hot. It feels luxurious but not terribly pricey.”

Why the Saatva Classic Earned Best California King Mattress for Back Pain

When you’re getting a big bed, you want even, reliable support throughout—it’s the best safeguard against both a saggy mattress and back pain. The Saatva Classic, with its two innerspring units, takes support seriously. It has several features that concentrate lift under the lumbar spine, helping to give an extra boost to this sensitive area. 

Furthermore, my own experience with this bed left me confident that it can work for just about anyone. You can customize its height as well as its firmness to suit your tastes. 

Saatva Mattress Side view in Sleep Advisor's testing studio.

Testing Soundbite

“If you deal with back pain, there’s extra lumbar support form in the class soft euro pillow top, plus two different layers of coils that distribute body weight from building around your lower back.”

Julia Forbes, Sleep Advisor Mattress Tester

What’s the Saatva Classic Made Of? 

The Saatva Classic comes in a Plush Soft, Luxury Firm, or Firm feel. You can choose between two heights: 11.5 inches or 14.5 inches. (Note that only the shorter version works with an adjustable base.)

Check out the Mattress Construction

The inside of the Saatva Classic Mattress
  • Organic Cotton Cover. A breathable, soft cover protected by a plant-derived antimicrobial treatment. Its quilting firms up in the middle, just under the lumbar spine. 
  • Euro Pillow Top. A 3-inch layer of plush foam for pressure relief.
  • Memory Foam Lumbar Crown. A strip of memory foam meant to both cushion and contour the lower back. 
  • First Innerspring Unit. Pocketed coils compress individually beneath you, with extra-strong coils located beneath the lumbar spine. 
  • Lumbar Zone® Active Spinal Wire. Nestled within the dual spring units, this bracing wire provides even more support to the lumbar region. 
  • Second Innerspring Unit. The base innerspring unit features interconnected coils for enhanced durability and sag-prevention. 
  • Foam Rails. Lining the edges of the bed, these high-density foam rails reinforce the sides. 

Customer Reviews of the Saatva Classic

The Saatva Classic rates 4.8 stars out of 5 on Saatva’s website. On Reddit, people tend to love this bed or have trouble finding the most comfortable firmness level for them. One user (u/cyberwizkiddo123) said “[It’s] beautifully constructed and very comfortable. I don’t recommend it if you are a very light sleeper and easily disturbed, the motion isolation for me is an issue.”

The Advisor Says: Its fancy quilted cover and generous foam layers make the DreamCloud Premier a slightly softer bed than the original DreamCloud. But, it still skews firm for a hybrid, so it’s best for back and side sleepers who like an initial bit of cushion followed by lots of lift.

Why the DreamCloud Premier Earned Best California King Mattress for Side Sleepers

Although the original DreamCloud is one of my favorite beds for stomach sleepers, side sleepers should feel much more at home on the DreamCloud Premier.

This model boasts a super-plush Euro top that dreamily cradles the hips and shoulders. It’s still a hybrid with plenty of support, and on a California King, you’ll have tons of room to reposition and sleep alongside a partner. 

Testing Soundbite

“Premier, meet side sleepers. Side sleepers, meet Premier. This mattress is a slightly upgraded version of the original, but it doesn’t sacrifice support for the extra cushion. The extra padding works great for those with sensitive joints, but with that extra softness comes a smidge less lumbar support.”

Julia Forbes, Sleep Advisor Mattress Tester

What’s the DreamCloud Premier Made Of? 

The DreamCloud Premier is 13 inches tall and has eight layers if you count its top and bottom covers. 

Look at the Mattress Construction

  • Layer 1 – Top Cover. Made of a cashmere blend, this Euro top cover feels invitingly soft.
  • Layer 2 – Quilted Memory Foam. This plush memory foam is quilted into the above cover. 
  • Layer 3 – Quilted Memory Foam. 
  • The second layer of foam in the Euro top, it bolsters the memory foam that precedes it. 
  • Layer 4 – Gel-Infused Memory Foam. Gel keeps this pressure-relieving layer of foam cool as it contours to your body.
  • Layer 5 – Transition Foam. A firmer layer of foam that protects you from feeling the spring unit below and encourages healthy alignment.
  • Layer 6 – Coil Unit. Pocketed coils with reinforced springs along the bed’s perimeter. 
  • Layer 7 – Base Foam. A strong foam base. 
  • Layer 8 – Lower Cover. Handles attached to this cover make the bed easier to move.

Customer Reviews of the DreamCloud Premier 

Coming in at 4.5 out of 5 stars on DreamCloud’s site, the DreamCloud Premier receives a majority of positive reviews. Users on the r/Mattress subreddit have mixed opinions, with some finding it too firm for their liking. Others say to give it a chance: “I hated it for the first 3 nights and swore it was going back, but both my partner and I are happy with the sleep we are getting and the relief we have both received with our back pain” (u/757gaycruiser).

Why the WinkBed Earned Best Hybrid California King Mattress

The WinkBed has a handcrafted design that emphasizes support, durability, and lift for your lower back. We think it’s the best hybrid bed to order in a California King size due to these factors plus its versatility—you can order it one of four firmness levels, depending on your tastes.

Loren described the WinkBed as having a “hotel-like feel” during testing, and that’s exactly what most people want from this luxurious size. She also enjoyed its springy responsiveness and the fact that it can accommodate all body types.

Testing Soundbite

“No matter which firmness you choose, the feel is pretty similar. The mattress is very bouncy and buoyant, and the pillow top layer adds a bed-rotting level of comfort while the coils keep your body mostly elevated on the mattress.”

Loren Bullock, Former Lead Product Tester

What’s the WinkBed Made Of? 

The WinkBed is 13.5 inches thick and arrives in one of four firmnesses: Softer, Luxury Firm, Firmer, and Plus. 

Look Closer at the Mattress Layers

  • Tencel™ Cover – Derived from the wood pulp of eucalyptus trees, this cover wicks moisture and stays refreshingly cool. 
  • Euro Pillow Top – A quilted pillow top with gel-infused foam for plushness and pressure relief. 
  • Additional Foam Layers – Between the top and the spring unit, you’ll find WinkBed’s proprietary LumbarLayer™ (which gives a boost of support to the lower back) as well as other specialized foams. 
  • Coils – Zones in the spring unit provide different levels of pushback to match the resistance your body needs. The coils are also stronger around the bed’s edges.

Customer Reviews of the WinkBed

On the WinkBeds site, the WinkBed has over 8,500 reviews and a score of 4.8 out of 5 stars. One drawback of the WinkBed mattress is that it might be too expensive for budget-conscious shoppers, but overall it offers excellent durability and customizable firmness options.

It’s a relatively pricey bed, so if you’re on a tight budget, consider some of the best affordable mattresses instead
At 15 inches high, this is a very tall and stately mattress, which makes it difficult to move once it’s unboxed

Why the Nolah Evolution Earned Best Soft California King Mattress

As the name implies, the Nolah Evolution mattress is an elevated luxury bed that should provide exceptional comfort for shoppers seeking a royal upgrade to a California King. It comes in three firmness options for your choosing, but if you’re looking for a sumptuously soft bed, stick to the Plush model.

The Evolution excels in both support and pressure relief, ensuring that you stay comfortably lifted the entire night. We found it accommodated just about every sleeping position, too, and had enough bounce to easily switch between them. The solid edge support also means you should be able to spread out to your heart’s content on the expansive surface.

Testing Soundbite

“However, my personal favorite aspect is the pressure relief! As a middle-aged CrossFitter with a janky hip, this bed eases so much of my pain.”

Sosha Lewis, Senior Staff Writer

What’s the Nolah Evolution Made Of? 

The Nolah Evolution stands an impressive 15 inches high, and has seven total layers including its top cover. It comes in Plush, Luxury Firm, and Firm models.

Dig Into the Mattress Construction
  • Layer 1 – Top Cover. A mix of organic cotton and ArcticTex™ fibers provide a comfortable and cool sleep surface.
  • Layer 2 – Euro Topper (2 inches). This top foam layer is quilted to conduct excess heat away from your body. There’s also a gusset around the perimeter to allow it to escape.
  • Layer 3 – AirFoam™ (2 inches). This hole-punched, dense foam layer provides pressure relief and is zoned for lumbar support.
  • Layer 4 – CoreComfort Foam (2 inches). An extra layer of more supportive foam.
  • Layer 5 – EverAdapt Transition Foam (1 inch). This foam provides some bounce, while helping to isolate motion as it transitions into the coil unit below.
  • Layer 6 – Coils (8 inches). Three zones of durable, individually wrapped coils.
  • Layer 7 – Base Foam. A foundational layer rounds out the mattress for stable support.

Customer Reviews of the Nolah Evolution

Earning 4.9 out of 5 stars from roughly 900 reviews on Nolah’s website, the Nolah Evolution seems to be a hit. In a review of the bed on the r/Mattress subreddit, u/cyriouslyslick said, “At my size [350 lbs, 6’ tall] I find it very plush, but still supportive.” Other users, however, have reported sagging along the edges and center of the bed after long term use.

Why the Bear Star Hybrid Earned Best California King Mattress for Couples

At a 6 out of 10 on our firmness scale, the Bear Star Hybrid fits right into the most versatile zone in terms of feel.

Couples with different firmness preferences may find it the ideal California King bed, as it can suit most sleeping positions and has some impressive extra features, too.

One of these is its Celliant® cover, which purportedly helps with muscle recovery after a strenuous workout or active day. 

Testing Soundbite

“The Bear Star Hybrid should perform quite well for couples. Its firm yet cozy feel should bridge the gap between people with somewhat different comfort preferences, and its cooling elements can help sleeping partners from overheating.”

Julia Forbes, Sleep Advisor Mattress Tester

What’s the Bear Star Hybrid Made Of? 

The Bear Star Hybrid is 13 inches high and has five total layers. 

Dig Into The Layers

  • Cover. Featuring both HydroCool® technology for cooling and the Celliant® performance textile for boosted muscle recovery, this is one of the most high-tech covers we’ve seen. 
  • Serene Gel Foam. A pressure-relieving foam that cushions the body and resists overheating. 
  • Responsive Comfort Foam. A bouncier foam that reforms easily to facilitate movement. 
  • Coil Unit. Individually wrapped coils offer reliable, sturdy support. They’re also stronger along the perimeter of the bed.
  • High-Density Support Foam. A grounding base for the entire bed.

Customer Reviews of the Bear Star Hybrid

Coming in at approximately 4.5 out of 5 stars on Bear’s site, the Bear Star Hybrid is a well-rated mattress. When it comes to customer reviews outside the platform, opinions are mixed on the bed’s firmness and feel. One user (u/nkell011) reported it was “much firmer than we anticipated” and that they “woke up with a stiff neck.” But another (u/kevaqua1) claimed, “Mine softened up after a couple weeks.”

Why the Brooklyn Bedding Aurora Luxe Earned Best Cooling California King Mattress 

If you’re a hot sleeper in need of a bigger bed, the Brooklyn Bedding Aurora Luxe is an exceptionally cool California King option. During testing, it took only a little more than five minutes to lower its temperature back to its original level—and then even a bit below it—after I lay down on its surface. 

My fellow tester Emma was also stunned by its abilities: “It’s one of the coolest sleeping mattresses that we’ve ever received. Truly … it’s so cold to the touch.” 

Testing Soundbite

“The magic really comes down to the cooling cover containing phase change material paired with cooling foam and breathable coils. During our testing, it quickly regulated body temperature and made the surface a cooler temperature.”

Julia Forbes, Sleep Advisor Mattress Tester

What’s the Brooklyn Bedding Aurora Luxe Made Of? 

The Brooklyn Bedding Aurora Luxe is 13 inches tall with six layers. It’s available in a Soft, Medium, or Firm feel.  

Look at the Mattress Construction

  • Layer 1 – Cover. GlacioTex™ fibers in this cover help to dissipate unwanted heat.
  • Layer 2 – CopperFlex™ Foam (1.5 inches). This responsive foam has both copper and phase change material inside it—both substances that encourage cooling. 
  • Layer 3 – Supreme Response Comfort Foam (1.5 or 2 inches). A springy and pressure-relieving foam. It’s thicker in the Soft and Medium versions of the bed. 
  • Layer 4 – Gel Swirl Memory Foam (1 inch) or VariFlex™ Foam (1.5 inches). The Soft and Medium models have gel swirl memory foam for further pressure relief. The Firm model has VariFlex™ foam with a more supportive feel. 
  • Layer 5 – Coil Unit. Individually wrapped coils make up the primary support feature of the bed, with reinforced springs along the edges.
  • Layer 6 – High-Density Foam Base (0.75 inches). A sturdy base on which the coils can rest. 

Customer Reviews of the Brooklyn Bedding Aurora Luxe

On Brooklyn Bedding’s site, the Aurora Luxe has a rating of 4.7 out of 5 stars and more than 4,000 reviews. On Reddit, one user (now inactive) reported their experience with the bed over the course of a week, and concluded that “We still really like the mattress. It has helped with my back and shoulder pain quite a bit.” Another user (u/koopa00) was disappointed and didn’t experience much temperature regulation from the bed: “I notice no cooling effect at all, regardless of what sheets I use. I’m not saying the bed runs hot, but it’s honestly no different than my previous memory foam mattress.”

Why the Titan Plus Earned Best California King Mattress for Heavy People

The Titan Plus was made with heavier sleepers in mind—it can support up to 1,000 pounds—but anyone who enjoys a firmer mattress can benefit from this painstakingly constructed hybrid. Its foams and coils form a supportive, robust California King-sized bed that still doesn’t skimp on the comfort factor.

“Unlike many mattresses that I have tried, my weight is evenly distributed over this surface, and I feel extremely comfortable,” said Patrick, one of our plus-size testers. 

Testing Soundbite

“Bottom line: for all plus-size sleepers, there should be plenty of support and pressure relief regardless of your sleeping position.”

Spencer Bland, Sleep Advisor Videographer & Mattress Tester

What’s the Titan Plus Made Of? 

The Titan Plus is 11 inches tall with four total layers. For an extra bit of cash, you can add a GlacioTex™ Cooling Cover to the top. 

Dig Into The Layers

  • Layer 1 – Quilted Gel Memory Foam (1 inch). This foam gives the bed a bit of softness at the outset, while the gel helps to prevent overheating.
  • Layer 2 – TitanFlex™ Foam (2 inches). A proprietary foam that contours to the curves and pressure points of the body without letting you sink too deep.
  • Layer 3 – Coil Unit (6 inches). Individually wrapped TitanCaliber™ coils provide responsiveness and further support. The coils along its perimeter have a higher gauge and are grouped more tightly, permitting sleepers to spread out without dipping at the edges.
  • Layer 4 – High-Density Foam Base (2 inches). The bed’s strong, durable foundation.

Customer Reviews of the Titan Plus

Users on Titan by Brooklyn Bedding’s site have given the Titan Plus a 4.7 out of 5 stars out of over 2,500 reviews. Discussing the bed on the r/Mattress subreddit, one user (u/Spectt69) reported, “I have no complaints. It is the best mattress I have ever had, probably because it is my first “plus size” mattress.” However, another user (u/Same_Relation_2798) found they didn’t feel supported, saying “no matter what position I slept in, I’d feel like a banana.”

Why the Plank Firm Earned Best Firm California King Mattress

Looking for a California King that’s built for firmness and support? Take a look at the Plank Firm—this all-foam mattress boasts two firmnesses in its flippable construction. You can pick between a traditional firm feel or an extra-firm feel if you’re looking for a truly unyielding surface.

Aside from its firm feel, the bed also boasts strong edges and some bounce. You should enjoy it if you prefer a firmer mattress, or if you’re a sleeper who needs extra support, like stomach sleepers and folks over 230 pounds.

Testing Soundbite

“It doesn’t get more solid than the Plank. This is one of the firmest mattresses on the online market.”

Julia Forbes, Sleep Advisor Mattress Tester

What’s the Plank Firm Made Of? 

The Plank Firm is around 10 inches tall with a flippable construction.

Dig Into The Layers
  • Layer 1 – Quilted Top, Extra-Firm Side (0.75 inches). On the extra-firm side, the top layer has no loft at all. 
  • Layer 2 – Support Core (6 inches). A dense, thick foam layer makes up the support for both sides of this firm mattress.
  • Layer 3 – TitanFlex™ Comfort Foam (2 inches). This layer of foam gives the less-firm side a slight amount of bounce and contouring ability.
  • Layer 4 – Quilted Top, Firm Side (1.5 inches). The standard firm side of the bed has just a bit of loft to it for a barely perceptible cushion.

Customer Reviews of the Plank Firm

On Plank’s website, the Plank Firm gets 4.8 out of 5 stars. Customers have discussed their experience with the Plank mattress on the r/Mattress subreddit. One user (u/salman15) originally stated that they “loved it so much that I didn’t want to get out of bed sometimes after a long night sleep.” Later, though, they complained of the mattress starting to sag after years of use: “I noticed that the mattress was sagging from the center. There was a clear body imprint.” They noted that this happened on the traditional firm side, but the extra-firm side held up.

What Is a California King Mattress? 

A California King mattress is an alternate, longer version of a standard King-size mattress. California King beds are 72 inches wide and 84 inches long, whereas traditional King mattresses are 76 inches wide and 80 inches long. These mattresses are also called Cal Kings, Cali Kings, and Western Kings.

The average price of the California King beds we tested and listed above is $2,065.

Ultimately, a California King mattress is best for taller sleeper or those who want a large but more narrow bed.

Pros and Cons of a California King Mattress

Pros
Enough length for tall sleepers – Sleepers over 6 feet tall may appreciate the extra space lengthwise a California king offers over a regular-sized king.
For couples and singles – A California king can be beneficial whether you sleep with a partner or are just looking for a luxurious bed to spread out on top of.
Fits in rooms – The more rectangular shape of a California king mattress might fit better in certain bedroom spaces.
Cons
Not as wide as a king-size bed – A king-size bed is going to be more square than a California king, so if you’re shorter, you may want more spaces on your sides rather than the bottom of your bed.
Difficult to find accessories – California kings are less common than regular-size kings, so you may struggle to find the sheets, pillows, and other accessories in the proper dimensions.

California King vs Other King-Size Mattresses

California is perhaps the most common specialty type of king, but did you know that there are other specialty king-size beds? Their names are just as stately as their sizes, which can get pretty gargantuan. The Alaskan King is 9 feet by 9 feet! Don’t believe me? Read on to see the difference between every specialty king size.

What to Consider in a California King Mattress 

There are plenty of things that go into a good bed, let alone a California King. We’ve outlined below some things you’ll want to keep in mind as you search for your perfect bed.

Height of Sleepers

While a King mattress is wider, the California King mattress is longer. If you’re well over 6 feet tall, you probably know the struggle of your feet hanging off the edge of the bed. In this case, a California King mattress is perfect because it’s 84 inches tall. This means it can accommodate sleepers up to 7 feet tall. 

For perspective, Kings can accommodate up to 6 feet and 6 inches (80 inches in length), so they still can comfortably fit taller folks. However, a Cali-King, even if you don’t use the full 84 inches, would give you even more legroom.

Bedroom Size and Transport

Like the state that they were named after, California Kings are long. They are often used in rooms that are long, but perhaps a little narrower than others. You will need to measure your room to ensure it can accommodate the bed’s size while leaving room for other furniture and walking paths. 

You will also want to account for the unique size when it comes to transporting your bed through various doorways and up or down staircases if you have them. 

Type of Mattress

California Kings come in many different mattress types. What works for you is going to depend on your specific needs and personal preferences.

From our mattress studio, images of our tested mattresses in different materials
Innerspring Mattresses

Traditional innerspring mattresses typically have interconnected coils and a thinner comfort layer on top. This type of coil system provides a lot of bounce, but the offset is that these mattresses don’t isolate motion very well. If you have an old California King bed, chances are, it’s an old innerspring.

However, many modern innerspring mattresses use pocketed coils that are individually wrapped in fabric. This allows the coils to move independently rather than as one solid unit, which reduces motion transfer from one side of the bed to the other.

Innerspring mattresses also allow for ample airflow, which often makes them a good choice for hot sleepers. The downside is that they don’t offer much pressure relief because of the thin top layer. That’s where hybrids come in.

Hybrid Mattresses

Hybrid mattresses combine foam and coils. This design can provide the cooling and supportiveness of innerspring mattresses with the pressure-relieving and motion-isolating properties you typically get from foam.

In addition to the cooling provided by the coils, some hybrid mattresses will also offer gel-infused foams, breathable fabrics, and other cooling properties that can provide substantial cooling benefits. The combination of coils and foam often makes them more expensive than innerspring or memory foam beds.

Many online California king mattresses are hybrid beds, so you should have a swath to choose from.

Memory Foam Mattresses

Memory foam mattresses usually contain memory foam at the top, followed by denser poly foam layers toward the bottom. These types of beds offer motion isolation and pressure-relieving contouring.

However, foam can be slow-moving, which may cause combination sleepers or sexually active couples to feel stuck when repositioning. Additionally, foam’s density makes it ideal for heat retention. Fortunately, manufacturers have taken note of this issue and implemented many cooling properties into their all-foam mattresses. You should be able to find an all-foam California King that’s built for you and your partner.

Latex Mattresses

Latex mattresses are more responsive and naturally cooler than memory foam and poly foam. Their responsiveness makes them great for combination sleepers, people with limited mobility, and sexually active people, as this material helps them move freely.

Some latex mattresses are natural, organic, and sustainable, putting them at the forefront for eco-conscious shoppers. Latex is known to be durable but is also one of the more expensive types of beds on the market.

It may be difficult to find a latex California King bed simply because this is a rarer mattress type.

Weight/Body Type of Sleepers 

A California King mattress will give tall sleepers plenty of room to move about. However, when considering the type of mattress that will work best for your weight and body type, the dimensions of the bed aren’t the only thing you need to consider. 

  • Lighter people need softer mattresses to keep pressure from building up.
  • Average-weight sleepers can be well-served by a variety of materials, but for the most part, they will want a bed that is medium-firm.
  • Finally, heavier people usually sleep better on firmer mattresses that prevent them from pushing through the upper comfort layers too quickly.

Sleeping Position 

The position you sleep in will make a huge impact on which bed you should choose, specifically when it comes to firmness levels. Typically, side sleepers may find better pressure relief on a softer bed, while back sleepers and exclusive stomach sleepers should like a firmer surface for spine alignment. 

Firmness 

The level of firmness that will work best for you will depend on factors mentioned above, such as your preferred sleep position and weight, but also any personal preferences. 

Most California King mattresses are available in various firmness levels. If you’re looking for the closest thing to a one-size-fits-most mattress (hint: there isn’t one), we recommend a medium bed. This is a tried and true preference for many sleepers, including those of average weight, combination sleepers, and those who prefer to sleep on their backs.

Edge Support 

Good support around the perimeter of your mattress means that you won’t feel as if you’re falling off the bed if you sleep near the edge. Even in a larger bed such as a California King, good edge support benefits those who co-sleep because it allows you to utilize the entire surface area. Additionally, having a reinforced perimeter can help those with mobility issues get in and out of bed more easily. 

Innerspring and hybrid beds generally have stronger edge support, whereas many memory foam and latex mattresses provide edge support through sturdier foams along the sides.

Motion Isolation

Co-sleepers should be concerned about their sleeping preferences as well as the movements of their partners. If the nighttime movements of your spouse, child, or pet are transferred from their sleeping area to yours, it can disturb your sleep. 

California King-size beds should give you plenty of room to move around, but the size won’t matter as much if your bed doesn’t isolate motion well. Memory foam and hybrid mattresses with memory foam generally perform better at keeping motion isolated to one side of the bed, though we’d recommend a memory foam mattress containing only foam if you’re an especially light sleeper.

Sex 

California King mattresses can give sexually active couples ample room to move around during their intimate moments. However, the type of material of the bed can help or hinder how easily couples can move about.

Latex, innerspring, and hybrid mattresses can offer more responsiveness and bounce to help prevent people from feeling stuck when they are engaged in sex. Memory foam offers gentle contouring, but its slow-moving nature may cause people to feel stuck when they are moving about during sex. 

Pressure Relief

There are few pleasures better than slipping into a spacious California King bed and feeling the strain and stress of the day melt away, and that’s why pressure relief is a highly sought-after characteristic for mattresses. 

Memory foam and latex beds can offer excellent pressure relief because these materials contour the body, which helps stave off pressure buildup. If you like the durability and bounce provided by innerspring mattresses, you may want to consider a hybrid instead. The upper foam layers provide you with more pressure relief than traditional innerspring mattresses, which typically only have a thin layer of cushioning between you and the metal coils.

Budget 

If you’re looking for a cheaper bed, this bed size may not be the right choice. California King and King mattresses are much bigger, costing more than smaller mattress sizes. Many manufacturers sell Kings and California Kings for the same price, but it depends on the brand.

Company Policies

Researching the manufacturer you’re considering is an important step when shopping for any mattress, not just for a California King. Check out the company site and make sure they’re transparent about their products and what it’s in them. We also recommend reaching out to customer service when you have questions, too, as it can be key in judging how helpful they may be when problems with your mattress arise down the line.

(Check our mattress reviews for our customer service scores, too!)

Shipping, Trials, Returns, and Warranties

If it’s your first time trying out this model, you may want to have the option to return, especially if you’re purchasing your mattress online. Most will ship for free to the United States (with exceptions for Alaska and Hawaii). Nearly all online mattress retailers offer a sleep trial, during which you can try out a mattress to decide if it’s a fit for you. They can last anywhere from 30 days (usually how long it takes to break in a bed) to a full year.

After that, it’ll be up to the warranty, which you should make sure you understand before making a final purchase. Some manufacturers offer lifetime warranties, but even these can come with stipulations.

Accessories for Your California King Mattress

Bed Frames

Given the unique size of California King mattresses, you will want to ensure that your frame matches the dimensions of your bed. California Kings are approximately 4 inches longer than a standard King mattress and have a width of around 4 inches less.

Some universal frames can be adjusted to fit a variety of bed sizes, but if your frame is designated for a King-size bed, it likely won’t be compatible with your California King mattress.

Sheets and Bedding

When shopping for sheets and other bedding, such as comforters and duvets, for your California King-size bed, you will need to keep the unique dimensions of your bed in mind. Therefore, try to find bedding specifically made for California King mattresses. For instance, a standard King-size comforter may touch the floor on the sides and come up short at the foot of the bed.

Best California King Mattress FAQs

How big is a California King-size bed?

A California King-size mattress is 84 inches long and 72 inches wide. It’s the longest standard mattress size available.

Is a California King bigger than a King?

A California King and King have roughly the same surface area. However, Cali King is both longer and narrower than a traditional King-size mattress, so it does offer more space for tall people to stretch out lengthwise.

Do King-size sheets fit a California King mattress?

No, King-size sheets are made to fit a shorter, wider mattress. If you buy King-size sheets for your California King-size bed, you’ll probably find that they’re too short to fit over the long sides of the mattress.

Why is this size called a California King?

Although there are several stories circulating the internet about the California King’s origin, Karin Mahoney of the International Sleep Products Association states that mattresses were developed in the 1920s for Hollywood celebrities, and this is why they were given their West Coast name. California Kings were actually designed before standard Kings. The demand for bigger beds increased after World War II, and manufacturers designed the regular King-size beds to fit on two Twin XL box springs.

How much is a California King bed?

A California King-size mattress usually costs more than 1,000 dollars, and especially luxurious models will cost more than 2,000 dollars.

Some mattress brands price their California Kings the same as their King-size models, whereas others make them a tad more expensive due to their more specialized status. Accessories and bedding for California King-size beds are also pricier than corresponding King-size versions.

Is there a bed bigger than the California King?

Yes. Texas, Wyoming, and Alaskan King-size beds are all bigger than California Kings (and traditional King-size mattresses). However, these specialty sizes are tough to find and even harder to shop for in terms of accessories.

Their dimensions are as follows:

  • Wyoming King: 84 inches long, 84 inches wide
  • Texas King: 80 inches long, 98 inches wide
  • Alaskan King: 108 inches long, 108 inches wide
