Best California King Mattress

Made with 2 inches of high-density memory foam, the all-foam Silk & Snow Mattress offers a medium (5) feel that conforms to sleepers to relieve pressure. The memory foam has an open-cell design and gel infusions designed to maintain a neutral temperature. A 2-inch high-density polyfoam transitional layer and a 6-inch high-density polyfoam base complete the design.

During partner tests, we found the Silk & Snow provides above-average motion isolation to keep disruptions to a minimum when sharing the bed. It’s also fairly easy to switch positions on this bed.

All of our testers weighing less than 130 pounds gave the Silk & Snow excellent overall ratings regardless of preferred sleep position. Side sleepers between 130 and 230 pounds also enjoyed its medium feel and all-foam construction.

Silk & Snow ships the mattress for free to the contiguous U.S. and Canadian provinces, with an extra charge for Alaska, Hawaii, and Canadian territories. This model has a 15-year warranty and a 100-night sleep trial with a 30-night mandatory break-in period.

Featuring the strong pressure relief and motion isolation you’d expect from a memory foam mattress at a below-average price-point, the Silk & Snow Mattress offers significant value for cost-conscious shoppers.

The DreamCloud Mattress features a quilted polyfoam cover sheathed in a cashmere blend that helps wick moisture away from the sleeper. This is followed by a layer of memory foam with gel infusions engineered to sleep cool. A layer of firmer polyfoam helps ease the transition onto the pocketed coil support core, and a final layer of polyfoam provides a sturdy base.

Because they are individually wrapped, the coils are quieter and transfer less motion than regular innerspring coils. The coil support core also adds bounce, aids with airflow and heat regulation, and helps strengthen the perimeter of the mattress to prevent feelings of roll-off along the edges.

Our testing team rated the DreamCloud as medium firm (6) on our 10-point firmness scale. They noted that its balanced feel performed well for back and stomach sleepers across all weight groups and side sleepers over 130 pounds.

Shipping is free to the contiguous U.S. DreamCloud offers a lengthy 365-night sleep trial with a 30-night break-in period. The mattress is backed by a limited lifetime warranty.

Cushioning yet supportive, the DreamCloud is a solid all-around pick for a variety of sleepers, particularly those who tend to overheat and people who value strong pressure relief in a hybrid mattress.

Saatva is best known for its flagship luxury innerspring mattress, but the company also makes a latex hybrid for those who prefer the feel of latex.

The 12-inch Saatva Latex Hybrid has a Euro-top design with a breathable cotton cover and a wool flame barrier, both of which are certified organic by the Global Organic Textile Standard (GOTS). Wool is known for its ability to wick moisture, helping keep the surface of the bed cool and dry.

Next, a 3-inch layer of natural latex with pincore holes adds bounce and extra room for airflow. The latex is zoned into five sections, with targeted support for the lumbar area. A pocketed coil base adds further support to maintain healthy posture. The entire mattress is hand-tufted and held together at the base, which is made with GOTS-certified organic cotton and wool.

Due to its breathable natural materials, the Saatva Latex Hybrid offers strong temperature regulation suitable for hot sleepers. Latex and coil layers provide good responsiveness, allowing for easy movement. Our testers noticed minimal sinkage around the perimeter, so sleepers should be able to spread out over the full mattress surface.

Rating a medium firm (6) on our firmness scale, we found this model is best suited to back and stomach sleepers, as well as side sleepers over 130 pounds. It received the highest grades from stomach and back sleepers between 130 and 230 pounds, who appreciated the support of its pocketed coils and the gentle contouring of its zoned latex layer.

The Saatva Latex Hybrid Mattress is available in the six standard mattress sizes as well as split king. Saatva ships mattresses with free White Glove delivery and optional old mattress removal in the contiguous U.S. The company offers a 365-night trial period, though returns are subject to a $99 processing fee. This mattress comes with a limited lifetime warranty.

If you like the feel of latex mattresses but also want the robust support of a coil-based core, the Saatva Latex Hybrid offers a best-of-both-worlds approach with sustainably sourced materials and zoned reinforcement for the lower back and hips.

Featuring a flippable design with a different firmness on each side, the 13-inch Layla Hybrid is ideal for sleepers with changing preferences or those who aren’t sure which firmness they prefer. The medium soft (4) side has 2.5 inches of copper-gel memory foam and 2 inches of zoned polyfoam. The firm (7) side has 1 inch of copper-gel memory foam and a 1.5-inch layer of zoned polyfoam. A 6-inch layer of pocketed coils functions as the support core for both sides.

Copper and gel infusions in the memory foam are designed to draw heat away from sleepers. Airflow can also circulate through the support core, and the coils have a double row of stronger coils around the edges to reinforce the perimeter of the bed. Handles are thoughtfully placed on the sides to assist with flipping the mattress, and the polyester-blend cover is removable for easier cleaning.

Between its two sides, the Layla Hybrid can accommodate sleepers of most body types and sleeping positions. We found the soft side most suitable for side sleepers under 230 pounds, though back and stomach sleepers under 130 pounds also enjoyed its plush feel. The firm side received the highest praise from side sleepers over 230 pounds and back and stomach sleepers over 130 pounds, who noted that their bodies sank just enough into the thin memory foam layer to relieve pressure without sacrificing support.

Layla ships the mattress for free to customers in the contiguous U.S. Additional fees apply for orders to Alaska, Hawaii, and Canada. The Layla Hybrid comes with a 10-year limited warranty and a 120-night sleep trial, though the company asks that you try the bed for at least four weeks before initiating a return.

With its choice of two firmness levels, our testers found the Layla Hybrid suitable for side sleepers in all weight groups. Its versatility also makes it a good choice for Airbnb rooms or guest bedrooms.

Casper’s Snow mattress lineup is designed with extra cooling features for people who have a tendency to overheat at night. The Wave Hybrid Snow has a QuickCool cover infused with phase change material engineered to feel cool to the touch. Beneath this is a layer of aerated polyfoam laminated with phase change material and another layer of latex with graphite bands designed to draw heat away from the sleeper.

Zoned memory foam and a final layer of polyfoam with targeted gel pods provide structure and pressure relief. The support core is made with pocketed coils and features a perimeter foam encasement for reliable edge support. All in all, the mattress stands 13 inches tall and has a medium (5) firmness level.

Despite the coil core, the Wave Hybrid performed well during our motion isolation tests and made little to no noise when testers moved across the surface. The coils also create a responsive feel that enables sleepers to switch positions with ease.

The Wave Hybrid received above-average scores from most of the members of our testing team, with side sleepers between 130 and 230 pounds and back sleepers under 130 pounds giving the strongest accolades. A notable exception was stomach sleepers over 230 pounds, who said they sank too deeply and felt slightly trapped in the foam and latex layers.

Shipping is free to the contiguous U.S. and Canadian provinces. Extra charges apply for shoppers in Alaska, Hawaii, and the Canadian territories. Casper offers a 10-year limited warranty and a 100-night sleep trial with a 30-night requirement.

Featuring a plethora of cooling features and a pocketed coil support core that promotes airflow, the Casper Wave Hybrid Snow is a great choice for sleepers who tend to overheat during the night.
