Best Split King Mattresses (2024) – Expert Tested

If you’re going to share a King-size mattress, you may as well ensure that your side feels just the way you like it. This kind of customizability is possible with a Split King — traditionally, two Twin XL mattresses positioned side by side. Because the sides of the bed are distinct, you’re free to have a softer or firmer sleep space than your partner’s. If you have an adjustable bed frame, you’ll also be able to move your side into new positions independently. 

What makes a great Split King mattress? Awesome edge support, a few different firmness options to choose from, and that crucial balance of softness and spine-aligning features. Informed by our testing, I’ve gathered the best Split King beds around for this list. 

Our Top Pick for The Best Split King Mattress

The Saatva Classic is our top pick for the best Split King bed due to its unmatched edge support, customizable firmness options, and pressure relief.

Sleep Advisor’s Testing Methodology

At Sleep Advisor, our mattress reviews are based on findings from in-person tests that allow us to have a genuine understanding of how the mattress feels and performs. Our team of testers hosts a variety of body types and sleeping preferences, so we’re able to get a truly comprehensive understanding of how a mattress performs. We test in every sleeping position and for a swath of performance categories.

For this roundup, we focused on the best mattresses for those looking for a Split King bed. We took several factors into account when devising our list, including different sleeping positions, cooling elements, pressure relief, motion isolation, and edge support.

We’ll dive into it more below, but read our full testing methodology here.

I love testing mattresses in the Sleep Advisor testing facility.

What We Want to See in a Split King Mattress

Features Good for Couples

Split Kings are usually marketed toward couples who can’t seem to compromise on a bed. So, it’s important that these Split King mattresses have other features that should benefit co-sleepers. We looked at things like motion isolation, responsiveness, and cooling to judge whether or not this bed is a good fit for folks who share the bed.

Multiple Firmness Options

Since most shoppers considering a Split King are looking to satisfy differing needs, we tried to find options for you. Some of the mattresses on this list offer multiple firmness models. If you need a soft bed but your partner needs a firm, buying two Twin XL mattresses in the appropriate feels can result in a well-tailored Split King bed.

Solid Edges

Since a Split King is essentially two beds put together, edge support can be useful to avoid creating a noticeable divot or gap in the center of the mattress. We tried to pick beds with edges that won’t egregiously sag to avoid this issue.

Why the Saatva Classic Earned Editor’s Pick

Saatva marries luxury and value in all their mattresses, including their flagship Classic model. It’s plenty customizable for couples looking for the perfect Split King mattress, with two different heights and three firmnesses to choose from. (Please note, however, that only the 11.5-inch height is compatible with an adjustable bed frame.) 

The Classic excels in responsiveness, pressure relief, and support, while also featuring strong edges so sleepers can make use of the bed’s full surface area. Tack on generous policies and a long-lasting structure, and it’s no surprise that the Saatva Classic earned the title of the best Split King bed.

Saatva Mattress interior
The construction of the Saatva Classic.

What’s the Saatva Classic Made Of?

The Saatva Classic is available in two heights (11.5 and 14.5 inches) and three firmnesses (Plush Soft, Luxury Firm, and Firm).

Inside the Saatva

  • Euro Pillow Top. Plush foams cushion you all over while quilting in the center keeps the lower back elevated.
  • Lumbar Crown. A crest of foam targets the lumbar area of the back for optimum support and pressure relief.
  • First Coil Layer. Individually wrapped coils are zoned to balance lift and give in all the proper places.
  • Spinal Wire. In between the two coil units is a bracing wire that promotes proper spinal alignment.
  • Second Coil Layer. Traditional interconnected coils add to the bed’s durability.
  • Perimeter Foam Rails. The sides of the mattress are reinforced with a tough foam frame to prevent sagging.

My Take: The Saatva Classic delivers a luxurious sleep experience with enough features to satisfy any customer seeking a high-quality, comfortable bed. The two coil units in this mattress amp up its support and durability, allowing it to last long without any sagging.

Pros
Something for everyone – With two height and three firmness options, it’s easy to tailor the Saatva Classic to your tastes.
White glove delivery – Saatva offers free white glove delivery with all their mattresses, which means they set up the mattress for you!
Cons
Returns cost extra – Returns will run you about $99, so take care if you like to try before you buy.
Could isolate motion better – The Saatva Classic is pretty bouncy; I noticed it definitely didn’t isolate motion as well as an all-foam bed.

Customer Reviews of the Saatva Classic

The Saatva Classic rates 4.8 stars out of 5 on Saatva’s website. One negative aspect customers found with the Saatva Classic mattress is that it may feel too firm for some users, while a notable advantage is its high-quality materials, providing durability and support.

Why the Nectar Earned Best Affordable Split King Mattress

Nectar is rightfully considered one of the first online mattress pioneers. Their original model is a mainstay on the bed-in-a-box market, but even so, they haven’t let the design grow stagnant. Instead, they’ve updated it multiple times to incorporate feedback and new features, all while preserving their commitment to affordability.

The Nectar’s reliable performance and welcoming price point make it a wonderful option for a reasonably priced Split King bed. As Emma, one of our expert mattress reviewers put it: “It’s truly a luxury feel at a lower cost.”

Testing the layers and construction of the nectar mattress

What’s the Nectar Made Of?

The Nectar mattress is a 12-inch-high memory foam bed with five layers, including the top and bottom cover. 

Inside the Nectar

    • Layer 1 – Cover. Polyethylene fibers make for a breathable cooling cover.

    • Layer 2 – Gel Memory Foam (2 inches). This memory foam should mold to your body and provide just enough comfortable sinkage while the gel within it prevents heat retention.

    • Layer 3 – Dynamic Response Foam (3 inches). This layer plays a role in both support and motion isolation, acting as a transitional layer between the top of the bed and the base layer.

    • Layer 4 – ActiveSupport Base Foam (7 inches). A dense foam layer creates the foundation for the mattress.

    • Layer 5 – Lower Cover. The bottom cover keeps the layers of the mattress in place and prevents unwanted slipping.

My Take: I think the Nectar is great for all-foam fans who love to sink into the comfy layers of their bed. This bed offers delightful pressure relief at a budget-friendly price, so your joints and your wallet can benefit.

Pros
Foam that pleases back and side sleepers – Our team loves this bed for both side and back sleeping.
Great motion isolation – Both Emma and Jill tested this bed with someone lying next to them and found that it capably absorbed movement.
Cons
It’s not springy – Given its all-foam design, I noticed that there isn’t a lot of bounce to the Nectar.
It could be cooler – “[The Nectar] didn’t provide as much cooling as we hoped, [which is] standard for beds without innersprings,” said Jill.

Customer Reviews of the Nectar Mattress

With thousands of reviews on Nectar’s website, the Nectar mattress has an average 4.8 out of 5 stars. One common customer complaint about the Nectar mattress is its longer-than-average break-in period, while many customers praise its excellent value and comfort once fully settled.

Why the Helix Midnight Luxe Earned Best Split King Mattress for Side Sleepers

The Helix Midnight Luxe is a medium-firm hybrid mattress built to accommodate a variety of sleepers, but it works especially well for side sleepers because it boasts soft, pressure-relieving foams above its strong coils. This combination cushions problem areas while keeping you lifted and properly aligned. 

Though Helix doesn’t offer the Midnight Luxe in a Split King option, you can easily make one by buying two Twin XL mattresses and pushing them together. Co-sleepers should also appreciate the breathability and bounciness that comes from the hybrid’s coils.

Helix Midnight mattress side view
The Helix Midnight Luxe in our testing studio.

What’s the Helix Midnight Luxe Made Of?

The Helix Midnight is 11.5 inches tall with six total layers. All foams used in its construction are CertiPUR-US® certified.

Inside the Helix Midnight Luxe
  • The pillow top.  Copper gel memory foam for cooling and pressure relief.
  • Helix Responsive Foam. A medium-firm feel that cradles and supports.
  • Second copper gel memory foam layer. Pulls heat away from the surface to help with cooling. 
  • Memory foam transition layer. Promotes added support and stability, along with even weight distribution. 
  • Innerspring unit. A layer of 1000+ individually wrapped coils standing that are 8 inches high.

DuraDense Foam. A base layer for stability and motion absorption.

Our Take: Based on our team’s experience with this bed, we think the Midnight Luxe’s combination of pressure-relieving and supportive materials could be especially great for most side sleepers above 130 pounds.

Pros
Lots of bounce – The combination of strong coils and responsive foams on top make this bed super springy.
Adaptable for many people – The bed’s softer Euro top, medium-firm feel, and supportive coils should work for a wide range of people.
Cons
So-so motion isolation – The Midnight Luxe has average motion isolation, which might not necessarily be an issue with a Split King.
Not the best for lightweight side sleepers – While we love this bed for most side sleepers, our lightweight tester did experience some pressure in her hip on this one.

Customer Reviews of the Helix Midnight Luxe

On Helix’s website, the mattress has over 6,000 reviews, scoring 4.5 out of 5 stars. Customers appreciate the Helix Midnight Luxe mattress for its customized support but have reported that it may not be the best option for those who prefer an exceptionally soft sleep surface.

Why the DreamCloud Earned Best Luxury Split King Mattress

It’s hard to believe that a high-end mattress like the DreamCloud could come at such a dreamy price. This bed is a hybrid with a super-lifted feel, topped with cashmere for a luxurious finish. It should work for nearly all sleeping positions and body types, so I call it a “jack of all trades” type of bed.

Folks wanting a Split King should appreciate that DreamCloud offers such a model, along with an adjustable bed frame to totally customize the experience.

Take a closer look at the mattress construction of the original DreamCloud mattress

What’s the DreamCloud Made Of?

The DreamCloud uses CertiPUR-US® certified foams in its 14-inch, seven-layer construction.

Inside the DreamCloud

  • Layer 1 – Top Cover. A cashmere blend cover makes this bed look and feel luxurious.
  • Layer 2 – Soft Foam (1.5 inches). A plush foam layer tops off the mattress for premium cushioning.
  • Layer 3 – Gel-Infused Memory Foam (1 inch). This layer adjusts to your body for a hugging and pressure-relieving contour.
  • Layer 4 – Transition Layer (2 inches). A layer of dynamic foam encourages proper alignment.
  • Layer 5 – Coil Unit (8.5 inches). Individually wrapped coils keep up the support while enhancing motion isolation. Thicker coils line the edges for reinforcement.
  • Layer 6 – Base Layer (1 inch). This foundation provides structure for the rest of the bed.
  • Layer 7 – Lower Cover. The cover on the bottom keeps the mattress and everything within it in place. There are also handles along the sides for easy maneuvering.

My Take: The DreamCloud is consistently one of my top mattresses to recommend and one of my personal favorites. It’s also pretty affordable; sales and coupons are frequent on DreamCloud’s site, so you can knock off dollars without worrying about sacrificing any quality.

Pros
Affordable luxury – Luxury Split King mattresses will usually cost you closer to $3,000, but the DreamCloud model retails for around $2,000.
Lifted feeling – I tried out every position on this mattress and felt supported properly in each one.
Cons
Not super contouring – This lifted feeling doesn’t lend itself well to the contouring cushion typical of most foams.
Lacking edge support – The DreamCloud has reinforced edges that hold up when you lay near them, but when it comes to sitting, it’s a no-go.

Customer Reviews for the DreamCloud

The DreamCloud Original scores a solid 4.7 out of 5 stars among customers on its site. While some customers appreciate the value and affordability of the DreamCloud Original mattress, others find it to be on the heavier side, which could make moving or rotating the mattress more challenging.

Why the Nolah Evolution Earned Best Soft Split King Mattress

The Nolah Evolution is a hybrid mattress, so it’s impressive that it feels so soft. Its coils sit beneath five foam layers that give the bed its cushiony, plush top. The gentle cradle should benefit anyone who needs pressure relief but doesn’t want to feel too “stuck” in their mattress.

The Split King model should work well for couples who want a soft mattress with some adjustability and an extra bit of motion isolation. You can also purchase two Twin XL mattresses if you want different firmnesses.

Testing the Nolah Evolution in our studio.

What’s the Nolah Evolution Made Of?

The Nolah Evolution has eight layers in its 15-inch-thick construction. It’s available in Plush, Luxury Firm, or Firm.

Inside the Nolah Evolution

  • Layer 1 – Cover. A mix of organic cotton and ArcticTex™ material creates a soft and cool sleep surface.
  • Layer 2 – Euro Topper (2 inches). Breathable foam and quilting with high thermal conductivity cushions your body and adds to the bed’s cooling capability.
  • Layer 3 – AirFoamICE™ (2 inches). This layer has graphite infused into its foam to speed up cooling while it relieves pressure. Around it and the layer above is an AirBreath™ gusset that allows any excess heat to escape.
  • Layer 4 – High-Resilience Foam (2 inches). This firmer foam adds support to the above comfort layers.
  • Layer 5 – Transition Foam (1 inch). A latex alternative, this robust and bouncy foam leads into the innerspring layer.
  • Layer 6 – Coil Unit (8 inches). Three zones of HDMax™ coils target different areas of the body to maintain alignment and ease pressure buildup.
  • Layer 7 – Foundation. The durable base of the bed is made up of recycled plant fibers.
  • Layer 8 – Bottom Cover. This handled cover helps with transport while the bottom resists slipping on your bed frame or base.

Our Take: “The Evolution is packed with soft layers for plush relief… When I crawled into this bed, I could really feel it gently cradle my body.” Stuart Petty, Sleep Advisor Mattress Tester

Pros
Has some bounce – The layers of foam on top make this bed uber-soft, but they don’t dampen too much of the bounce from the coils underneath.
Cooling capability – The Nolah Evolution was designed with hot sleepers in mind.
Cons
Too soft for some – It might be too plush for sleepers who need more support, like stomach sleepers or folks over 200 pounds.
High price point – The Nolah Evolution is one of Nolah’s higher-end mattresses—especially for a Split King, which costs a little over $3,000 before sales and coupons.

Customer Reviews of the Nolah Evolution

The Nolah Evolution rates 4.5 stars out of 5 on Nolah’s website. Customers frequently commend the Nolah Evolution mattress for its exceptional pressure relief and cooling properties, but some have observed that it may produce slight off-gassing upon unboxing.

Why the Bear Elite Hybrid Earned Best Split King Mattress for Back Pain

When it comes to back pain, sleepers are going to need a bed that gives them proper support but doesn’t feel so firm that it exacerbates pressure buildup. The Bear Elite Hybrid has cushioning foams on top for some cradling and a zoned coil unit to keep the lower back lifted. 

Couples wanting a Split King should also appreciate that the bed’s sturdy edges strengthen the perimeter, so there should be little to no sinking near the sides or center.

Bear Elite Hybrid lightweight back sleeper test
Testing the Bear Elite Hybrid in our studio.

What’s the Bear Elite Hybrid Made Of?

The Bear Elite Hybrid is 14 inches thick with five layers. It’s available in Firm, Medium, or Soft models.

Inside the Bear Elite Hybrid

  • Layer 1 – Cover. This cover is made up of Phase Change Material for cooling and Celliant® fibers for muscle recovery. The latter reportedly converts excess body heat into infrared energy to promote tissue oxygenation.
  • Layer 2 – Memory Foam. Copper in the first foam layer keeps heat at bay while acting as a natural antimicrobial barrier.
  • Layer 3 – Dynamic Transition Foam. This layer of foam contours to your body while easing you into a comfortable sink.
  • Layer 4 – Coil Layer. The individually wrapped springs are zoned to balance support and give across different areas of the body. Reinforced coils also line the edges.
  • Layer 5 – Support Foam. A dense foam base keeps the mattress stable.

Our Take: “Sleepers with back, hip, or shoulder pain will love the zoned coil system. It is built to relieve pressure in the areas you sleep on and support the areas that need a little extra boost, specifically the lumbar area.” – Stuart, Sleep Advisor Mattress Tester

Pros
Cooling champ – The Bear Elite Hybrid has plenty of features that regulate temperature and make it a great fit for hot sleepers.
Strong edges – Stuart found out during testing that “the edges are extra-reinforced by the zoned coil system, so you can really take advantage of the entire surface of the bed.”
Cons
Wait for a sale – Before any markdowns, it will cost you nearly $4,000 for a Split King.
Not for stomach sleepers – We don’t think it’d be a good fit for stomach sleepers—they’re liable to sink too low.

Customer Reviews for the Bear Elite Hybrid

According to Bear’s website, the Bear Elite scores about 4.5 out of 5 stars. Some customers find the Bear Elite Hybrid mattress too firm for their liking, but it receives praise in its reviews for its advanced cooling technology and pressure relief.

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

Even on a Split King, you might feel your partner’s heat from the other side of the bed—or perhaps you’re just prone to overheating. No need to fear, the Brooklyn Bedding Aurora Luxe is here. This luxurious hybrid works to keep the temperature down with a plethora of cooling features. 

It starts out with a GlacioTex™ cover that should feel cool to the touch, which works alongside layers of breathable foams and a pocketed coil unit. 

Though Brooklyn Bedding doesn’t offer the Aurora Luxe in a Split King option, you can easily make one by buying two Twin XL mattresses and pushing them together.

What’s the Brooklyn Bedding Aurora Luxe Made Of?

The Brooklyn Bedding Aurora Luxe is about 13 inches tall. It features a total of six layers including its cover.

Inside the Aurora Luxe
  • Layer 1 – GlacioTex™ Cooling Cover. The cooling gel in this cover reacts to excess heat or cold to keep your skin at a comfortable temperature for sleep. You can also pay to upgrade to a pillow top cover.
  • Layer 2 – CopperFlex™ Foam. This super-elastic foam is meant to mimic latex, providing all of the contouring, pressure relief, and bounce, but with a higher durability. 
  • Layer 3 – Supreme Response Comfort Foam. A second layer of foam boosts the responsiveness of the layer above it, ensuring it bounces back after you switch positions.
  • Layer 4 – Gel Swirl Memory Foam. Another cooling layer, this gel foam relieves pressure buildup and adds even more responsiveness to the bed.
  • Layer 5 – Zoned Coils. These coils are zoned to ensure lift and give in all the proper places. Those around the edges are also reinforced for a stronger perimeter.
  • Layer 6 – High-Density Foam Base. A durable foam foundation layer.

My Take: I was super-impressed with the Aurora Luxe’s ability to keep cool. During one of our temperature gun tests, I recorded the surface temperature of the mattress actually going down, which is rare to see. 

Pros
Plenty of bounce – Not only are the springs on the Brooklyn Bedding Aurora Luxe responsive, the foams are too! I rated the bounce on this bed as “perfect” for my needs.
Multiple firmness options – The Aurora Luxe comes in Soft, Medium, and Firm. So, there’s no need to compromise; just order two twin XLs in each desired firmness.
Cons
So-so edge support – Lying near the edge was alright, but you’ll definitely sink if you sit at the edge.
Firm for some – We tested the Medium variant of the Aurora Luxe, and even that, we thought, was a little too firm for some folks.

Customer Reviews for 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. Customers praise the Brooklyn Bedding Aurora Luxe mattress for its advanced cooling features, but some have mentioned that it is relatively expensive compared to other options.

Why the Titan Plus Earned Best Split King Mattress for Heavier Sleepers

Folks over 200 pounds often contend with sagging mattresses that don’t give them the proper support. The Titan Plus was designed specifically for these sleepers, so there’s no need to worry about sinking too deep.

The coil unit should evenly distribute weight while maintaining lift, and the foam layers on top should provide just the right amount of cushioning comfort. The Titan Plus is designed to hold up to 1,000 pounds, and a Split King should maximize this ability by acting like two separate mattresses.

Though Titan doesn’t offer the Plus in a Split King option, you can easily make one by buying two Twin XL mattresses and pushing them together.

Brooklyn Bedding Titan Plus Construction from the lab

What’s the Titan Plus Made Of?

The Titan Plus has four layers and is 11 inches tall.

Inside the Titan Plus

  • Layer 1 – Quilted Gel Memory Foam (1 inch). The surface of this mattress is cushioning and cooling, and it is designed to retain its shape while bearing weight.
  • Layer 2 – TitanFlex™ Foam (2 inches). TitanFlex™ foam adds pressure relief as it contours to your body.
  • Layer 3 – Coil Layer (6 inches). Individually wrapped TitanCore springs give the bed its support. They’re reinforced along the edges to prevent unwanted sagging.
  • Layer 4 – Foam Base (2 inches). A high-density base of foam provides the sturdy foundation for the coils and comfort layers above.

Our Take: “I definitely sink in a little bit, but this mattress feels supportive enough that I don’t feel stuck at all. Unlike many mattresses that I have tried, my weight is evenly distributed over this surface and I feel extremely comfortable.” – Patrick, Sleep Advisor Mattress Tester

Pros
Isolates motion well – We noticed during testing that this bed could absorb movement despite its sturdy construction.
Versatile – This bed was designed for plus-size folks, and they’ll be happy to know that it can support you in any sleeping position.
Cons
Not for lightweight sleepers – Though heavier folks should rest easy, if your partner is on the petite side, they might find the bed too firm and unyielding.
Cooling costs extra – If you want extra cooling at the surface, you’ll have to pay extra for the GlacioTex™ cover.

Customer Reviews for the Titan Plus

Users on Titan by Brooklyn Bedding’s site have given the Titan Plus a 4.7 out of 5 stars. Customers find the Titan Plus mattress to offer exceptional durability and support, but some mention that it might be too firm for those who prefer a softer feel.

Still thinking? Take a look at our Titan Plus review or our picks for the best mattresses for heavy people and best mattresses that won’t sag.

What Is a Split King Mattress?

A Split King mattress is the same size as a King mattress, measuring 76 by 80 inches. However, the difference is in the structure itself because a Split King is actually split in half, hence the name. This makes it look like two Twin XL mattresses next to one another. 

Each of these two beds measures 38 by 80 inches. The Split-King design allows partners to better customize their side of the bed based on their specific needs. 

Illustration of a Couple Resting on a Split Adjustable Bed

What to Look for in a Split King Mattress 

A Split King mattress is an exceptionally versatile option for partners with different sleeping habits. Many types are available, and there are certain factors to consider before purchasing a Split King bed to ensure you’re getting the best bed for you and your partner. 

Good Features for Couples

If you’re getting a Split King bed, odds are you are part of a couple, which is why a good Split King mattress should have features ideal for co-sleepers. Specifically, we consider good motion isolation, responsiveness, and cooling to be beneficial to most couples.

  • Motion isolation – Motion isolation is a mattress’s capability to keep motion isolated and prevent it from moving to other parts of the mattress. This can help prevent one partner from being awakened by the other’s tossing and turning. While you’re a lot less likely to feel anything on a Split King, it still doesn’t hurt to have this feature. See More: Best Beds for Couples
  • Responsiveness – Sexually active couples usually look for a bouncy, responsive bed, but with a Split King, things can get a bit complicated. In other words, the middle of the bed can be a little uncomfortable for some people. This is where the two mattresses come together, and the middle can have stitching that’s sometimes bulky. Whether or not this is comfortable and suitable for sex depends on the particular model you buy. Learn More: Best Mattress for Sex
  • Cooling – If you’re sleeping beside someone, that extra body heat can quickly turn a cool sleep space warm. Cooling mattresses can include specialized features such as cooling covers, gels, copper, and breathable materials like cotton and coils. It’s also important to mention that some mattress types are naturally more cooling than others. For example, latex and hybrid beds are more cooling than all-foam mattresses. However, many memory foam beds now come with gel infused into their foam to help with cooling.

Firmness 

Firmness reflects how soft or hard a mattress feels, and a Split King can make it possible to have two in one. In other words, you can have one side softer than the other if needed. 

Think about your weight and preferred sleeping position when choosing a firmness, and make sure the other side is a good fit for your partner’s weight and sleeping position. 

That said, you should confirm that a particular mattress provides different firmness options for each side because not all brands allow this. 

Titan Plus pressure testing
The Titan Plus has a distinct firm feel (7.5 out of 10 for firmness), making it great for heavier people looking for a split-king bed.

Edge Support

Edge support is always important for people who like to spread out and often sleep near the edge of the bed. Most companies reinforce this area in different ways, but how good the edge support is will depend on the particular bed and its materials. Hybrids often have stronger edges, but even memory foam and latex beds can do a good job if there’s reinforced foam around the perimeter.

Type of Mattress 

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

Innerspring Mattresses

An innerspring mattress has coils acting as the main support layer. These beds usually have only one comfort layer and fabric that covers the coils. This is the oldest and most traditional type of mattress. They’re usually beneficial for those who don’t need a lot of cushioning and prefer bouncy beds. 

Hybrid Mattresses 

Hybrid beds also have coils but are different than innerspring mattresses because they have more comfort layers. This type is essentially a combination of innerspring and all-foam beds, so it’s often on the pricey side. A hybrid mattress provides excellent support thanks to the coils, but it also has comfort foams for added cushioning and pressure relief. 

Memory Foam Mattresses 

Memory foam mattresses are popular due to their pressure-relieving properties. These combine several foam layers, usually with memory foam on top for pressure relief and denser poly foam below for support.  Although they don’t have much bounce, they’re excellent at isolating motion, which means motion won’t travel across the mattress when someone moves around. That said, couples don’t need to worry about this with Split King beds as the mattresses are separated.

Latex Mattresses 

Latex mattresses provide pressure relief similar to memory foam models, but they’re bouncier. Often, latex beds are made with natural or organic latex, as well as other eco-friendly materials. They are also naturally cool, so they don’t retain heat like memory foam does. Latex beds are usually more costly, but they are highly durable as well.

Other Considerations When Shopping for a Split King Mattress 

Adjustable Base Compatibility

If you have an adjustable base, a Split King mattress could be a perfect addition to enhance the overall experience. 

However, it’s important that your adjustable base is also a Split King so that each partner can lift or lower their individual side as desired. Another thing to consider is whether your Split King mattress is compatible with an adjustable base since not all mattresses work with adjustable bases. 

Looking for your perfect bed frame? Check out our list of the best adjustable bases.

Sleeping Position 

Our testers test each sleeping position to make sure each mattress fits the right sleeper

If you usually sleep on your stomach, you probably need a firmer bed than your partner, especially if they’re a side sleeper. This is where a Split King mattress can help as it allows you to have two mattresses in one. You can choose one side that fits your sleeping position and the other that’s more comfortable for your partner’s sleeping position. 

Weight/Body Type of Sleepers 

How much you and your partner weigh is also an important factor that affects a mattress’ overall support and comfort. For example, lighter-weight people often prefer softer beds that allow them to sink in more to receive enough pressure. Conversely, heavier sleepers often need firmer mattresses that can do a better job of keeping them lifted for good spine alignment. 

A Split King mattress allows you to have different firmness and support levels on each side to accommodate different body types. 

Pressure Relief 

Pressure relief is a major factor for many people, especially those who sleep on their side. Side sleepers need maximum pressure relief around the shoulders and hips, which is why they often go for softer mattresses with comfort layers made from memory foam or latex. 

More: Best Mattress for Pressure Relief

Bear Elite Hybrid average weight back sleeper test
The Bear Elite Hybrid earned a 5 out of 5 for support, making it an excellent bed for pressure relief and back pain.

Budget 

Regardless of the specific model you choose, a Split King size will always be more costly because it’s one of the larger bed sizes. However, the price is often the same as a King-size of the same brand. 

To help you save money, consider shopping during major mattress sales. Additionally, shopping online means you’re buying directly from the manufacturer, which helps cut overhead costs.

Nectar Mattress Sleep Advisor
The Nectar is a high-quality affordable bed that comes in a split-king size.

Bed Frames for Split King Mattresses

A Split King mattress is the same size as a King mattress, which means you can use a King-size frame with both models. However, you’ll have a small gap between the two Twin XL beds that make up a Split King. 

In the case of adjustable bed frames, it’s helpful to get a Split King adjustable base rather than a King size. This way, if one partner wants to sleep on an incline and the other doesn’t, there’s no issue.

Explore our picks for the best bed frames here.

Tips for Keeping Split King Mattresses from Separating

After a while, you may notice your Split King mattress separating. This is easy to spot by checking the gap in the middle. To help with this, you can tie the two beds together with any of the following items:

  • Zip ties
  • Velcro straps
  • Bungee cords
  • Connecting straps

Split King vs. Other Mattress Sizes

Split King vs. King Mattresses

A Split King mattress is the same size as a King mattress; the only difference is that a Split King is separated in the middle. This means you’re actually getting two beds in one. 

Although the size remains the same, a Split King is a bit more versatile and suitable for partners with very different sleeping habits. For example, if your partner often turns during the night, you’re unlikely to feel this on a Split King mattress because there’s a gap between your side and their side.

Browse the Best King Mattress picks, tested by our experts.

Split King vs. California King Mattresses

A California King mattress is larger than a Split-King or regular King bed. 

Some brands also offer a Split California King option, which is the same as a standard California King, but again, there’s a gap in the middle. 

Explore our picks for the Best California King Beds.

Best Split King Mattress FAQs

How much does a Split King mattress cost?

A Split King mattress is one of the more expensive sizes because it’s also among the largest options. However, in most cases, the price of a Split King model is the same as the King-size one.

How big are Split King mattresses?

A Split King mattress measures 76 by 80 inches, which means it has two Twin XL mattresses measuring 38 by 80 inches individually. In some cases, you may notice an inch or two difference, but that depends on the brand.

Can I use King-size sheets on a Split King bed?

You can use King-size sheets on a Split King mattress if you already have King-size sheets. This will also help to cover the gap between the two beds to make it more aesthetically pleasing. That said, if you and your partner often struggle with pulling the covers, you also have the option to buy two Twin XL sets.
