Helix’s proprietary Memory Plus Foam layer relieves pressure from the hips and shoulders, areas where side sleepers need the most cushioned support.

If that’s the case, you can take things a step further than just getting a bigger bed, and opt for memory foam—a material that’s renowned for its ability to isolate motion. (You’ve probably seen the commercials with the person jumping beside a precariously balanced wine glass on a mattress.

) There’s no one who does memory foam better than Tempur-Pedic. The brand’s Tempur-Adapt line has three different mattresses, the Adapt, ProAdapt and LuxeAdapt. Each one offers a different amount of Tempur’s memory foam for various levels of pressure relief, according to the company.

The mattresses also come in different firmness levels, soft, medium and firm—and you can get a medium hybrid if you prefer mattresses with a coil base.

What the reviews say: “We are in love with our need mattress,” says one reviewer, who also notes it’s great for back and side sleeping.

But Avocado doesn’t stop at using organic latex that it sources directly. In addition, the cover is made from cotton and wool that’s organic and sourced “from a farmers’ society” that the company owns.

Plus the mattress has just about every certification it can get, from Oeko-Tex Standard 100 to Greenguard Gold to Made Safe. Materials aside, it’s a great choice in terms of sensation, too. The Avocado Green Mattress has a medium firm sensation according to the company—though if that will be too firm for you, the company offers an add-on pillow top for an additional cost.

What the reviews say: One reviewer who purchased a king with the built in pillow top writes, “we have both been very happy with the comfort, cooler sleeping temperature and sleep experience of this mattress. ” The reviewer self-identifies as a “50+ year old with aces and pains,” and explains, “I can roll over!

We’ve researched more products than we care to count, and, like everyone, we snuggle up in our own mattresses each night.

We combined our expertise and research in sleep with our own experiences as well-seasoned sleepers to put together this list. We narrowed down products based on their key features, and selected options for material preferences, different budgets and even nighttime temperature. Each mattress that we selected is highly reviewed, by customers like you, and the companies offer generous trial and warranty policies—because it’s hard enough to buy a mattress online, you have to sleep on the thing to really know whether you like it.

Finally, we made sure to add non-standard sizes, like split and California kings, for anyone who needs them. We regularly update this story to ensure accuracy. It was last edited in January 2023.

What You Should You Consider When Shopping For A King Size Mattress There are plenty of things to keep in mind as you shop for your next mattress. First and foremost, you’ll want to think about your sleep position and how the mattress will feel. Side sleepers often feel better on softer mattresses, whereas back sleepers need a medium firm surface.

Stomach sleepers, in contrast, tend to do best on a firm mattress. If you’re shopping for a king size mattress, there’s another consideration you don’t need to weigh as heavily as with other sizes: edge support. Edge support refers to how well the edge of the mattress withstands pressure if you sit on it to tie your shoes, or sleep clinging to the side.

This tends to be more of a concern with queen size mattresses and smaller, just because those beds are more cozy for two people, and you may wind up right on the edge, whether you want to or not. With the ample space of a king size bed, this isn’t something to take as seriously. What Is The Best King Size Mattress? The best king size mattress starts with finding the best mattress for you.

We named the Nectar Premier Copper our top king size mattress overall thanks to its crowd-pleasing features including hybrid construction, cooling features and great price. That said, we included picks to cater to different sleep needs and feel that each model on this list is the best in its category. How Much Does A Good King Size Mattress Cost? The bigger the mattress, the pricier it is.

As such, king size mattresses are usually the most expensive of any model (with the exception of specialty sizes like California or split king mattresses, of course). You can generally expect to spend anywhere between $1,000 and $4,000 (or more) for a quality king size bed. Exact prices will vary based on materials and construction.

The cost of beds on this list ranges from $1,299 to $3,395. Is A California King Bigger Than A King? It’s a common misconception that California kings have larger dimensions, overall, than king mattresses. The surface area of the two is actually very similar.

The biggest difference is in the height of the mattress. A king is the largest standard size bed you can buy and measures 76 inches wide by 80 inches long. A king can comfortably accommodate two adults plus small children and/or pets.

California kings, sometimes called Western kings, have grown in popularity and are available at many online retailers now. This size is narrower yet longer than a traditional king mattress. These mattresses measure 72 inches wide by 84 inches long.

California king beds are ideal for taller individuals. More King Size Mattress Stories To Shop Great king size beds come in many forms.
