For anyone who requires a little extra space during their slumber, investing in a king size bed is common sense. But for some people, purchasing a California king size bed is a better choice. First, let’s start with the basics: what exactly is a California king? A California king is four inches longer than a traditional king mattress, but that also means you may have to sacrifice a certain amount of width. For tall sleepers (especially anyone over 6’4”), this extra length makes a huge difference.
The history of this bed goes all the way back to the post-WWII era when a mattress merchant from LA had the thought that Californians had large enough homes (and lifestyles) to justify this oversized bed. As he started churning them out for celebrity mansions, they gained popularity all over the world.
You might also opt for a California king if you have pets that like to sleep at the foot of your bed, or if these dimensions fit better in your bedroom. Another reason people prefer these beds is because of the appearance it provides. Generally, a narrower bed can make your bedroom appear more spacious, offering a well-balanced aesthetic. Just remember to take dimensions before purchasing, so you can figure out what size of bed works best for your specific living space.

They sell both a fully foam construction and a hybrid, that blends traditional memory foam with springs. And good news for the environment: every mattress cover is created with up to 57 recycled bottles.

3. The Purple Mattress
MOST UNIQUE PICK
Purple mattresses aren’t foam, nor are they spring-based. Instead, it’s constructed of a polymer that feels more like silicone or a gel. Unlike memory foams that heat up fast and give in to wear and tear over time, Purple’s top layer is made out of a cool, soft, and flexible polymer material that can be stretched without worry of ripping. Its top layer is set up in a grid formation, creating hundreds of tiny squares across your mattress’s surface. It’s just the right amount of support, whether you’re a back, side, or stomach sleeper.

This mattress has a medium-plush feel with solid support, and one customer writes, “I used to wake up and turn side to side 4 to 6 times an hour. Sleeping flat on my back was impossible. Side sleeping would result in severe deep throbbing in my numb areas. Now I wake only 3 or 4 times a night.” It also comes with 2 free memory foam pillows.

5. Signature Design by Ashley Chime 12″ Medium Firm Memory Foam Mattress

It can support a range of sleepers, with one buyer commenting, “I LOVE this bed, I am a big guy 6’3 300lbs and I fit comfortably on it and it forms to body.” Other buyers who dislike overly plush beds found that the “slightly firm” texture was ideal.

6. Tuft & Needle Original Foam Mattress
BEST COOLING PICK
Unlike other mattresses constructed with latex or memory foam, T&N’s Adaptive foam mattress uses an open-cell structure with a flexible sleep surface that molds to your body. Unlike these other materials, the Tuft & Needle Adaptive foam pulls heat away from the body thanks to cooling graphite and gel beads hidden inside. As one Amazon reviewer puts it, “Memory foam beds used to burn me up but I’m perfectly cool in this bed.” There are zero harmful chemicals typically associated with foam mattresses.

9. Layla Sleep Copper Infused Mattress
MOST SUPPORTIVE
Layla combines a thermal gel infused with copper to keep you cool all night long and prevent heat from being trapped. It does have a medium firmness level that may be too soft for some sleepers with back or joint pain. Their unique foam layering provides motion transfer control, but the most innovative factor in the Layla mattress is its ability to be flipped. One side is firmer while the other is softer, bringing the incredible value of two mattresses for one.

Big Fig Mattress
BEST FOR PLUS SIZE SLEEPERS
You don’t often find beds that are designed specifically for people with a bigger figure, but this is the demographic for whom comfort is most important. For plus-sized individuals, foam mattresses often have poor edge support or swallow you up entirely. That’s why Big Fig’s hybrid construction was carefully engineered, with a stronger-than-ever foundation that combined comfort and support. Say goodbye to sweaty sleep nights with the cooling ThermoGel technology that’s activated by the presence of body heat. Fans of the brand say it’s “worth every penny” with “no sagging at all”.
