The four firmness levels of the WinkBed are medium soft (4), medium firm (6), firm (7), and firm (8). The mattress features a Euro-top padded with adaptive foam, which is infused with cooling gel intended to disperse body heat. High-density polyfoam beneath the top layer provides additional contouring and support. The base layer contains pocketed coils arranged in a zoned layout, ensuring extra reinforcement for the midsection and minimal sinkage along the perimeter. The entire mattress is encased in a Tencel cover.
WinkBed mattresses ship free to the contiguous U.S. Customers may purchase White Glove delivery and old mattress removal as well. The mattress comes with a 120-night sleep trial and lifetime warranty.
The Premier has a cashmere-blend Euro-top cover that feels soft against the skin. The Euro-top is quilted with memory foam to create an exceptionally plush surface. The cushioning is further enhanced by a layer of polyfoam beneath, which conforms closely to your body. A transitional layer of polyfoam offers additional contouring but is firmer than the comfort layers to prevent you from sinking too deep into the bed. A support core made of pocketed coils offers targeted pushback to prevent uncomfortable sagging, and thicker coils reinforce the edges of the mattress.
The DreamCloud Premier comes with a generous 365-night sleep trial and free returns. Those who keep the mattress after this period will also receive a lifetime warranty. Shipping within the contiguous U.S. is free.
The mattress features three layers of foam and has a medium (5) feel. It begins with a top layer of memory foam infused with a cooling gel. This foam has a higher density composition than some competing memory foam beds, which generates stronger support. The next layer is made of polyfoam that balances cushioning with support, while the bottom layer is dense and supportive to create a sturdy base for the bed. The removable and machine washable cover is made of a polyester and spandex fabric blend.
Silk & Snow offers free shipping to the contiguous U.S. You can try out the bed for 100 nights and return it within this timeframe for a full refund. The mattress is also backed by a 15-year warranty.
The Birch Luxe is a high-end mattress made with wool, cashmere, latex, and steel coils. The premium materials offer more comfort than the average hybrid model, and they boast several certifications to ensure the bed is as eco-friendly as it is comfortable.
The mattress begins with a plush quilted Euro-top and organic cotton cover. Next is a layer of wool and rayon that cushions the body and serves as a fire retardant. Organic cashmere fibers followed by two additional wool layers enhance the plushness and regulate temperature, thanks to their natural breathability. A proprietary Pulse latex layer balances contouring and bounce, while the sturdy steel coils are zoned to provide extra support in the lower back and along the perimeter. The cotton and cashmere are both GOTS-certified organic, and the latex has certifications from GREENGUARD Gold and eco-INSTITUT to show it has met rigorous health and safety standards.
The Helix Midnight is a hybrid mattress with a responsive feel and a well-cushioned foam surface. This design benefits side sleepers who need a bed that supports the body but also cradles areas with pressure buildup.
The comfort system in the Helix Midnight is made of two foam layers. The top layer is Memory Plus Foam, a proprietary memory foam that cradles the body to support the spine and reduce pressure but also offers more bounce and retains less heat than traditional viscoelastic foam. This springiness is complemented by an underlying layer of transition polyfoam that fortifies the comfort system against an excess amount of sinking or sagging. The support core is made with individually wrapped coils that are strengthened around the edge.
The Helix Midnight has a medium firm (6) feel that should feel comfortable for a broad swath of sleepers. With ample contouring from the Memory Plus Foam, this model is excellent for most side and back sleepers, especially those between 130 and 230 pounds. The contouring cushions the shoulders, hips, and spine while the coil system amps up responsiveness to support the lumbar region. The responsive surface also makes it easy to change positions and move on the mattress.
At an accessible price-point, the Helix Midnight is a solid choice for people who want a quality bed but are working with a tight budget. For those with a bit more to spend, the Helix Midnight Luxe adds another layer of memory foam, plus an enhanced coil core with a zoned support system.
Our testers found that the Nectar Premier Copper excelled at pressure relief tests, providing ample cushioning for sharp pressure points like your shoulders and hips. Another area where this mattress earned high marks was motion isolation. The thick memory foam layer efficiently absorbs movement, preventing it from rippling across the surface. This bed felt most comfortable for the side sleepers on our team, but it also performed well for back sleepers who weighed up to 230 pounds.
The support core is built from pocketed coils that are zoned and reinforced at the edges. A layer of polyfoam rests above the core and prevents sleepers from sinking too deeply into the mattress, even when using the softest model. Proprietary graphite-infused polyfoam called AirFoamICE gently cradles your body and helps draw excess heat away from you while you sleep.
Six standard sizes are available, as well as a split king size for people who own adjustable beds. Nolah provides a 120-night sleep trial as well as a lifetime warranty, though you can opt out of the free trial for added savings. Free shipping is available to shoppers in the contiguous U.S. and you can choose to add old mattress removal and set up at checkout.
The Brooklyn Bedding Aurora Hybrid is a hybrid model available in three different firmness levels. Across all firmness options, the mattress is designed with cooling features that should keep the bed at a comfortable, cool temperature for hot sleepers.
Our testers with back pain often benefit from mattresses with cushioning for the spine and robust support to maintain healthy sleep posture. The Bear Elite Hybrid is a hybrid with foam layers that relieve pressure and evenly distribute weight, while a coil system keeps your body on an even plane. With three firmness options to choose from, you can pick the design best suited for your sleep position and body type.
The Bear Elite Hybrid comes in medium (5), medium firm (6), and firm (8) options. All three models begin with a quilted cover and layer of adaptive memory foam. Underneath is a polyfoam transitional layer that acts as a buffer between your body and the coils. These comfort layers vary in firmness depending on which firmness option you choose. Pocketed coils reinforce the sleep surface and strengthen the edges of the mattress. The coils rest on a polyfoam base layer for extra stability.
The medium firm and firm options of the Bear Elite Hybrid are easy to move across without sinking or feeling stuck. This can be attributed to a coil system that makes the surface bouncy and reinforces the perimeter, which may appeal to couples who prioritize a responsive mattress for sex. The Celliant-blend and PCM cover effectively keeps the surface cool by offsetting heat retention from the foam layers. Steady airflow through the coil layer provides additional thermoregulation.
Many mattresses that cater to heavy sleepers end up sacrificing some cushioning for support, but the Titan Plus Luxe from Brooklyn Bedding is a notable exception. This hybrid model has a foam and coil design that cushions your body while still offering plenty of sturdiness to keep you well supported.
The surface of the mattress is quilted with an inch of memory foam infused with a cooling gel. This is followed by a thicker layer of TitanFlex foam, which contours to the body but less so than the memory foam. Beneath is a transition layer made of Energex foam with a firmer feel, followed by a thick layer of TitanCaliber coils that generate strong support. For an additional fee, you can add a GlacioTex Cooling Cover. This is made with phase change material that helps keep the surface cool.
Our team at Sleep Foundation relies on rigorous hands-on evaluations as well as years of experience in the sleep product industry. We understand that mattress comfort is largely dependent on individual needs and preferences, so our team includes all sleeping positions with different body types. This way, we can be inclusive of as many sleepers as possible in our California king mattress picks.
To find the best California king beds, we performed various tests using special tools to measure pressure relief, temperature neutrality, and motion isolation. Our testers also sit, lie down, and move around on the mattress surface to evaluate firmness, support, and edge support. The top performers in our tests are reflected in the list of picks above. 041b061a72
