What is the best king size mattress?

That’s a question that many people looking to buy a new bed are throwing out into the internet, hoping to receive an unbiased, thorough and fact-based answer. And this “Best King Mattress” list is going to give you just that.

We’ll talk about the reasons for purchasing a king-sized mattress, and then move on to the list itself. The best king size mattress providers that we’ll be covering are:

Why Look for the Best King Size Mattress?

King-sized mattresses are usually seen as the biggest beds you can purchase. There are bigger sizes (i.e. Cal King), but these are usually more “custom” - as far as the base models are concerned, Kings often take the lead.

Why would anyone need the best king size mattress?

First of all, let’s talk about the people that live and sleep alone. This group of individuals might be looking for the best king mattress in order to sleep like, well… a king. Since the bed is going to be huge, a single person sleeping on it could twist and turn all they wanted - there’s just that much space to go around!

Furthermore, a mattress of this size is somewhat of a “safe bet”. While you might live alone right now, who knows - perhaps you’ll meet your future significant other tomorrow? The best price king size mattress will allow you to rest assured that you’d be able to sleep with another person on it, no problem.

That said, it’s worth mentioning that couples are way more likely to go out and look for the best king size mattress. It simply makes sense - if you live with a partner, and want a comfortable bed to sleep on without the fear of it becoming a Charlie Foxtrot, you’d probably want to go for the bigger version of the mattress.

One last thing before we jump into the list - if you’re looking for the best king mattress under 1000 bucks, you’ll find some options here, too. While there are such products in the market, they’re not all that common - remember, this isn’t a “best king mattress under 1000” list, after all.

1. Saatva - Bouncy Innerspring Design

Ranks #1 out of 7 Mattresses

Saatva is somewhat opposite to mattresses such as Nectar in that it’s designed in a traditional, old-school-innerspring-mattress kind of way. While this design does have its pros and cons, the benefits are actually best-felt on a king-sized bed.

For starters, Saatva does an amazing job at keeping you cool all throughout the night. It’s somewhat of a given with innerspring mattresses - their coil-on-coil design makes the bed extremely breathable, as opposed to all-foam products that tend to struggle heavily with heat issues.

To add to that, choosing Saatva as the best king size mattress, you’ll notice straight off the bat that you can sit, place items or even sleep on any of the bed’s edges - they’re as sturdy as they come. This is, again, thanks to the coil-based design of the bed - a king-sized all-foam mattress would likely struggle with edge support quite a bit.

All of that being said, as you can probably guess for yourself, while Saatva exceeds in all of the areas in which foam mattresses lack, the opposite is also true. While foam products such as Nectar are going to provide you with some amazing motion isolation and conforming features, Saatva isn’t going to be the best bed for that job.

What is the King-Sized Saatva Mattress Price?

Pricing-wise, a king-sized Saatva mattress will come out to be $1499 USD. Now, you’d think that this is rather expensive, but it’s actually a really good price for a reliable and time-tested innerspring product. If you’re still wondering what is the best king size mattress, do give Saatva a chance.

2. Nectar - Good Quality Materials

Ranks #2 out of 7 Mattresses

Nectar is one of the more popular and well-known mattress brands out there. If you’re looking for the best king size mattress that would be made out of high-quality foam material, this might very well be one of your best bets.

The mattress is absolutely wonderful at isolating any and all noise. This means that, whether you sleep or jump on the bed, you shouldn’t be worried about it squeaking and crackling - that’s the magic of foam.

Speaking of the magic of foam, another big criterion that you should take into account while choosing the best king size mattress is motion isolation. While it may not be as important for solo sleepers as for couples, purchasing a king-sized bed, you’d definitely want it to isolate as much motion as possible.

Nectar does that pretty well.

Customers report the mattress being very well-built - the high quality of materials and Nectar’s attention to detail really does show on the final product. This is also an important aspect as far as the best king size mattress is concerned - bigger mattresses tend to wear down faster, mostly because of their size and (rarely, but it does still happen) uneven weight distribution.

These things are not going to be a problem with the beds on this list, though. Nectar is no exception.

Finally, it’s worth mentioning that Nectar’s flagship product is probably best-suited for people who prefer to sleep on their sides and backs. This is mostly because of the fact that the mattress is great at alleviating back pain through the elimination of painful pressure points all throughout the body.

What is the King-Sized Nectar Mattress Price?

Pricing-wise, a king-sized Nectar will cost you $899 USD. Honestly, when you take all of the amazing features of the bed into account, this is an absolute bargain! A great contender for the spot of the best king size mattress under 1000 bucks.

3. Puffy - An All-Around Well-Built Foam Bed

Ranks #3 out of 7 Mattresses

Puffy is a foam mattress. By many accounts, it’s one of the better foam mattresses in the current market.

Customers note that Puffy is going to be great for anyone who likes the traditional feeling of a memory foam mattress. The bed comes equipped with some unmatched motion isolation. In turn, it does lack a little bit in the responsiveness department, but this shouldn’t be a major issue.

If you love the feeling of foam, but would still like to have some of the better features of a spring-based mattress, then you might love the Puffy Lux model. It offers all of the same features as the original Puffy, and, in addition to that, has some pretty good responsiveness and sturdy edges.

Puffy is a great contender for the spot of the best king size mattress solemnly based on the fact that it’s priced really fairly, and is probably the best-rated memory foam mattress alternative around. Sure, you might sleep pretty warm, but that’s almost to be expected when it comes to all-foam mattresses.

What is the King-Sized Puffy Mattress Price?

Pricing-wise, the Puffy king size mattress is going to cost you $1050 USD. As for the Lux version, it will total out at $1695 USD. Considering the reputation that Puffy has garnered over the years, these prices are more than acceptable.

4. Layla - Flippable Mattress Design

Ranks #4 out of 7 Mattresses

Layla is a foam-based bed. It is one of the more unique entries on this list, mainly because it is a flippable mattress - this means that you can turn the bed at any given time, thus adjusting the firmness setting!

Needless to say, that has some pretty good benefits as far as the best king size bed is concerned.

One of the most notable of these benefits is, of course, the fact that the bed is going to be suited for both people who like to sleep on softer and firmer surfaces. This way, Layla encompasses a broad group of people!

The bed itself is great as far as motion and noise isolation are concerned, and it is better at keeping you cool at night than most other foam mattresses out there. Layla does lack a little bit when it comes to responsiveness, but it’s not too odd, seeing as it’s a foam bed.

What is the King-Sized Layla Mattress Price?

A king-sized Layla mattress is going to cost you $999 USD. Definitely one of the cheaper options in the current market!

5. New Purple - Unmatched Temperature Control

Ranks #5 out of 7 Mattresses

Purple is a company that offers a really well-made foam mattress. That’s not all, however.

In this best king size mattress review, we’ll be looking at the New Purple - a one-of-a-kind hybrid.

Most Purple customer reviews seem to agree - the New Purple is one of the best hybrid mattresses in the game right now. It has taken all of the great features of the flagship Purple bed, and upped the stakes to a whole new level.

The New Purple has found a way to combine two very different features - motion isolation and bounciness. While this is the goal for the majority of hybrids out there, the New Purple has probably pulled it off the best.

In addition to that, the bed is extremely good at keeping the temperature at a comfortable level while you sleep. No more heat waves - Purple uses some special technology to keep the sleeper’s body cool all throughout the night.

Choosing the New Purple bed as the best king size mattress in the current industry, you’ll be able to pick from three different firmness levels. The only notable downside of the product, however, is the price tag.

What is the King-Sized New Purple Mattress Price?

A brand-new king-sized New Purple mattress will cost you $1899 USD. This is actually on the pricier side of things, but if you’re still wondering what is the best king size mattress, then the New Purple might be able to answer that question for you.

6. Loom and Leaf - Luxury All-Foam Design

Ranks #6 out of 7 Mattresses

Loom and Leaf is a luxury foam-based mattress. As you’d probably expect, it’s a bed that’s made for people who truly do love and value the feeling of a foam bed.

Loom and Leaf comes with multiple different firmness options, and exceeds in all of the areas in which you’d expect a foam mattress to exceed in. Motion isolation, durability and comfort are the “name of the game” for the company.

That being said, it would seem that Loom and Leaf have placed all of their eggs in the “foam basket”. There are some customer complaints about the bed being a bit smelly and warm to sleep in.

Smell-wise, it’s normal for a brand new mattress to have a scent. It usually dissipates in like a week or so. However, nobody likes sleeping hot - this is a bit of a more difficult problem to solve. Memory foam mattresses struggle with this all the time, and it would seem that Loom and Leaf is no exception to that rule.

What is the King-Sized Loom and Leaf Mattress Price?

As far as pricing goes for this contender for the spot of the best price king size mattress, it’s priced at a hefty $1799 USD. Not cheap, but again - it’s sold as a luxury mattress, so one would probably expect no less.

7. Avocado - Green and Vegan Models Available

Ranks #7 out of 7 Mattresses

Avocado offers customers two different beds - Avocado Green and Avocado Vegan. Both of these beds are practically the same, except that the Vegan version comes equipped with organic cotton instead of wool.

Avocado, as you might have gathered, is a green company - purchasing a mattress from them, you can be sure that you’ll receive a product that has been handled in the most eco-friendly ways possible.

And that’s not just a marketing schtick, either.

A hybrid mattress, Avocado Green is very durable, and does a great job at keeping you - the sleeper - cool at night.

To add to that, the mattress is on the firmer side of things - this means that it has some pretty swell edges as far as sturdiness is concerned. Some customers do report an occasional noise coming from the mattress, but overall, the situation seems to be quite manageable.

What is the King-Sized Avocado Green Mattress Price?

The king-sized Avocado Green mattress will cost you $1699 USD. The price for the Vegan version is also identical. While it won’t really for people who are looking for the best king mattress under 1000 bucks,  it’s still a rather reasonable price.

Conclusions

That’s the end of our “Best King Size Mattress” list. All of the providers mentioned on this list come equipped with their own sets of pros and cons - the ultimate decision will lie on your own, personal preferences.

Best of luck in finding the ideal king-sized mattress for yourself!


Other Less Favoured Mattresses in This Category

Here are other mattresses related to the category but not as favoured by MyBestMattress readers yet. In my personal opinion, today there are much more optimal mattresses in the list with the higher rating that I'd recommend for the same price range or less.

Zenhaven - Built Out of Luxury Latex

Zenhaven is a latex-based luxury mattress.

Latex mattresses are rather interesting - they’ve been gaining popularity as of late, and are often considered to be some of the best products for back pain healing. Needless to say, a king-sized Zenhaven bed is going to be great for all types of sleepers, with people who like to sleep on their backs appreciating the product the most.

Zenhaven’s latex mattress offers some very good motion isolation and conforming features. As with most other latex-based products, the bed might come packed with some slight odors - they should, however, disappear in a couple of days. Additionally, Zenhaven’s customers appreciate the fact of just how truly silent the mattress is - that’s one of the more notable features of latex, after all.

As for the negative sides of the bed, there are two.

First of all, weak edge support. While latex isn’t well-known for having good edge support, it’s even more so prominent with Zenhaven. Given the overall quality of the bed, this really does stick out.

The other thing that might throw a lot of people off is the price. Remember - Zenhaven brands itself as a luxury mattress - and the price does show that.

A king-sized Zenhaven mattress is going to cost you $2499 USD. Yup, really.

If you’re looking for the best price king size mattress, Zenhaven would probably be on the opposite side of the spectrum. However, if you can afford it, it’s definitely an interesting luxury bed indeed.

Casper - A Medium-Firm Foam Bed

Casper (the original product) is an all-foam mattress. It’s a bit firmer than average, and will so suit people who are struggling with back, hip, shoulder and neck pain.

Furthermore, the mattress is great for people who tend to move around the bed in their sleep. Casper isolates motion just as well as any other contender on this list.

The mattress isn’t at all bouncy, though - since responsiveness is a key factor for couples who want to improve their sex life, Casper might not be the ideal option for such people.

The king-sized version of the Casper mattress is $1395 USD. That’s a pretty average price tag! So, for anyone looking for the best king size mattress for a bit over 1000 bucks, do check Casper out.

FAQ

Do top rated mattresses offer a money-back guarantee? Is there a catch?

All of the top mattress brands offer a money-back guarantee. The free trial usually starts from 90 to 100 nights, and if you don’t like the mattress, you can simply give it back. The majority of best mattress providers will not only give your money back but will also come to get it for free. If the mattress provider is reputable, there won’t be any catch - everyone understands that you have to try the mattress before knowing if it fits you.

How is MyBestMattress different from other similar mattress review sites?

We are not here for competition, our main mission is to make the process of choosing the right mattress easier. We aim to provide you with unbiased, reliable and in-depth mattress reviews that will answer all of your questions and make sure there’s no uncertainty left. To make no questions unsolved, we analyze thousands of users’ reviews and present our readers with real-life advice. MyBestMattress does not take any endorsements & payments, unlike a lot of similar sites. You will also find genuine user reviews only, since we eliminate spam & fake feedback daily.

How do you decide which mattresses are the best?

We consider a number of factors before the best mattress is decided. The main focus is put on global user feedback, gathered from user directories, Trustpilot, social media groups & hidden forums. Our researchers also investigate all the public information about each provider, as well as mattress specifications & main features. All the data is then analysed by our data scientist using Pandas with Python. We don’t let any biased information slip into our mattress reviews, so the top rated mattresses are really worthy of their position.

What is a memory foam mattress?

Memory foam mattresses are created mostly from polyurethane and have additional chemicals added that increase its viscosity and density. It’s also often called “viscoelastic polyurethane foam”. In order to create the air movement and let your body “breath” while you sleep, it has open foam bubbles. Memory foam mattresses are created in a way to adapt to your body curves and to also recover their original shape after you get up. Therefore, this kind of top mattresses offer you the feeling as if is created specifically for you.

How long do top rated mattresses serve?

The durability of a mattress depends on the provider and the quality of the materials used. Usually, you get a 10-year warranty, which will be valid in case of any defects. Normally, mattresses will serve you from 7 to 10 years, or even longer. Thus, when you buy the best mattress, you should take it as a long-term investment.

What is off-gassing? Is it poisonous?

Off-gassing refers to the odor which comes from a new mattress. It’s the process that happens when volatile organic chemicals (VOCs) leak out of the mattress foam into the air. Those chemicals include both human-made and natural components, including formaldehyde, chlorofluorocarbons (CFCs), benzene, trichloroethane, and perfluorocarbons. Top rated mattresses will have zero or very minimal off-gassing. Many of them are sent to the customer already after the off-gassing. Is it dangerous, though? Even though the smell can be unpleasant, there’s usually only a very small amount of chemicals that can do no harm to your health.
