Best California King Mattress – Our 12 Highest Rated Products for 2023

The Midnight is a hybrid mattress from the Helix brand. The Helix Midnight’s medium-firm feel is very versatile, which should accommodate most sleep preferences and body types, including couples sharing a Cali-King bed.

The Helix Midnight’s construction includes multiple foam layers and a set of pocketed coils. Sleepers should feel quality pressure relief from the Memory Plus Foam and High-Grade Polyfoam. At the same time, the coil unit and DuraDense foam at the base should give sufficient body alignment to help prevent back pain and keep the sleeper from feeling stuck in the mattress. Topping off the Midnight is a soft-knit cover for breathability, which should help hot sleepers stay cool throughout the night.

What’s worth mentioning?

• The foams in the Helix Midnight are CertiPUR-US® certified, and these beds are manufactured in the United States.
• Customers get 100 nights to test out the Midnight in the comfort of their home before committing to their purchase.

Nectar has really made its name known in the industry and for good reason. Their Nectar Mattress is made from memory foam that should give you that classic contouring feeling. Its cooling cover and gel-infused foam layers should keep things breathable, and the soft conventional foam should allow a little more bounce than the average all-foam to make repositioning at night simple.

Nectar works on any foundation, including adjustable and platform bases, so buying your new Cal king bed frame should be a little easier when choosing this mattress.

What makes it stand out?

• Nectar has some high-quality features, and the average sleeper should find its medium firmness comfortable and pressure relieving.
• With a 365-night trial, lifetime warranty, and fair pricing, you should feel like you got a great deal when buying a Nectar.

The DreamCloud brand cuts out the retail middleman in order to sell their high-quality mattresses at an affordable cost. Additionally, the 365-night trial and lifetime warranty they offer consumers is a great deal. The DreamCloud Premier is a hybrid bed that scored at a medium firmness, making it a versatile choice for those who share a bed with a partner.

The DreamCloud Premier stands at an impressive 14-inches tall, so you will have to consider that when choosing a new frame to fit this bed. The mattress may be somewhat tall for certain headboards or footboards.

Why we picked it

• DreamCloud Premier is covered in a lush Eurotop cover and combines foam and individually wrapped coils for optimum comfort and support. 
• The coils in this mattress are individually wrapped to mitigate motion transfer. The foams on top should also help isolate motion so that couples don’t disturb one another. 

Heavier individuals, this mattress is constructed for you. WinkBed Plus is a hybrid made from highly durable foam, latex, and a 5-zone pocketed-coil system. Just because it is durable does not mean it's uncomfortable; the soft gel-infused foam hugs your body in all the right places, and the coils make sure the hips, back, and shoulders are well-supported.

On top of all of that, the company offers a lifetime warranty and durability promise so you can feel comfortable spending your hard-earned cash.

What is special?

• This is the first luxury mattress made specifically for those over 300 pounds.
• Its highly dense foams are designed for resistance and to reduce sagging, and the coils are specially reinforced, so it should last for many years to come; in fact, the company boasts that it is “possibly the most durable mattress on the market.”

Saatva offers a luxurious, pillow top innerspring bed that is also environmentally friendly. Although you can order Saatva online, it does not arrive in a box like most online-only mattress brands. With free white-glove delivery, you do not have to worry about removing your old bed or installing the new one.

Along with the innerspring base, there is a memory foam section in the lumbar area to give some relief to the hips and core. If you want the feel of a more traditional bed, this should be a comfortable choice.

Why is it special?

• With Saatva, you can choose the firmness and height of your bed. There are three firmness options (Plush Soft, Luxury Firm, and Firm) and two heights (14.5 inches or 11.5 inches).
• It has a coil-on-coil system, which should make this bed breathable and bouncy.

If you’re in search of a great bed for athletes, then consider the Bear Star Hybrid. This mattress provides a balance of supportive firmness and versatility to adapt to different sleep positions and body types.

The Bear Star Hybrid features a Celliant® cover, which is said to improve recovery, making this a great selection for athletic sleepers. Below the cover is a copper-infused memory foam for cooling and pressure relief. The following layer is a transitional comfort foam, followed by an 8-inch coil unit for responsive support and airflow. The Bear Star Hybrid’s base consists of a high-density support foam.

What’s worth noting?

• The Bear Star Hybrid’s use of foams and individually wrapped coils to help curb motion transfer, which is appealing for couples sharing a bed.
• Your purchase of a Bear Star Hybrid comes with an impressive 120-night trial and lifetime warranty.

If you’re a side sleeper, good pressure relief is going to be essential in your search for a new mattress. For Brooklyn Bedding, pressure relief is a top priority. The company’s Aurora Luxe model is a high-end hybrid bed that is 13 inches of quality foam and coils for a quality sleep experience.

Most notably for side sleepers, the Aurora Luxe is built with three comfort layers, including CopperFlex™ foam, TitanFlex™ foam, and gel memory foam. Customers can also choose from three firmness levels to find the most comfortable feel for their body frame.

What stands out? 

• The Aurora Luxe helps hot sleepers stay with multiple cooling resources. TitanCool™ is the brand’s copper-infused gel foam that resists heat. They also use a latex alternative that should provide temperature regulation and give some bounce, and the pocketed coils should allow for plenty of airflow.

Nolah is a bed-in-a-box product made with three layers of varying foams certified by the CertiPUR-US® program for health and safety standards. Their AirFoam™ is made with little air pockets that help regulate heat, and the high-density foam should create a durable product that lasts for years.

Nolah is a medium firmness. This medium comfort level should be great for back sleepers since the firmer layers can keep the spine in good alignment while the top comfort layer relieves pressure in areas like the shoulders and legs.

What’s its best feature? 

• Nolah’s commitment to American workers is impressive, especially for those who want to help the local economy. According to their site, all of their products are made in the United States, which means a Nolah purchase is 100% American-made.
• Nolah is shipped in an eco-friendly box and, if returned, is recycled or donated.

When it comes to eco-friendly, non-toxic materials, the Birch Natural mattress goes big. Each California King-sized Birch boasts an organic cotton cover, organic wool in place of man-made fire retardants, and natural Talalay latex derived from the sap of rubber trees.

As a hybrid bed, the Birch provides superior support with individually wrapped coils underneath its latex layer. The coils along the borders of the mattress have been reinforced so that sleepers don’t feel unstable when they’re on the edges, which means you can safely invite your partner (and pets) to spread out.

What makes it special?

• The Birch has earned multiple certifications for its natural components from multiple organizations, including GREENGUARD Gold and GOTS.

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

The Titan Plus has two layers of foam at its surface: a 1-inch layer of gel memory foam that should help with cooling, followed by a 2-inch layer of the brand’s patented TitanFlex™ comfort foam, which contours to the curves and pressure points of the body without letting it sink too deep. Beneath these foams are close to 1,000 individually wrapped TitanCaliber™ coils. These springs provide responsiveness and further support, all without sacrificing motion isolation.

What do we love about it?

• The Titan Plus can support up to 1,000 pounds, making it one of few mattresses on the market designed for plus-sized users.
• The coils along its perimeter are a higher gauge, permitting sleepers to spread out without dipping at the edges.
