Our Reviews of 7 Best King Size Mattresses

Best Overall — Editor’s Choice — Puffy Lux Mattress

Puffy Mattress

Highlights

  • removable cover for effortless maintenance (great for allergy-prone sleepers);
  • reinforced edges to provide extra space;
  • three adaptive comfort layers for unparalleled pressure alleviation;
  • noise-free when bearing weight, making it ideal for couples.

Standing tall at the top of our best King-size mattresses list is the Puffy Lux Mattress. This mattress is a premium hybrid mattress designed to give you that balanced feel of support and tension relief. It is as comfy as they come. When I slept on the Puffy, I noticed how well it cradled my pressure points and kept my back in a good position, in fact, I woke up with my back tension gone.

Sleepers may also love the fact that the Puffy Lux isn’t likely to sleep hot. Yes, it has conforming comfort layers. However, one of them is gel-infused, the other is pretty responsive, and the third works to wick the excess moisture away. Add a breathable coil core, and you get a mattress that remains neutral all through the night. As proof, I did not experience overheating even when sleeping on one side and sinking deeper into the mattress.

Highlights

  • extended sleep trial to ensure customer satisfaction;
  • patented technology to deliver optimal spine support;
  • sturdy edges to provide more sleeping space for couples;
  • responsive feel, making it easier for sleepers to switch positions.

The next item on our list of the best King size mattresses is this hybrid by Saatva. Now, it seems like the company put a lot of thought into this mattress’s design to make sure it would work for a wide range of sleepers. Not only does it come in multiple comfort options but also has a peculiar construction.

There’s a lumbar support zone to guarantee proper spinal alignment during the night. And that’s something even the more expensive competitors (like the Cool Bliss, for example) cannot offer. Additionally, the Saatva comes with one of the longest sleep trials on the market. It would be an excellent option for hesitant shoppers or sleepers who have pain-causing medical conditions and require more time to get used to their new bed.

Best Cooling Mattress - Eight Pod 3 Mattress

Eight Sleep Pod 3

Click the button below to check current price 

Check Current Price Read our detailed review

Highlights

  • It maintains a cool surface using a hydro-cooling system for sleepers to stay comfy through the night. 
  • The Eight Pod 3 uses a dual-zone adjustable temperature feature which users can tweak to achieve better rest. 
  • A combination of different mattress layers provides ample cushion, bounce, and support for sleepers.

The Eight Pod 3 is a tech-based mattress that comes in king size and is designed for an all-round cooling effect for sleepers. This mattress has a medium firm top using a cradling memory foam layer. So, hot sleepers can feel cradled using this bed and yet maintain their cool. The Pod 3 uses a network of tubes hewn into the mattress cover to create a water flow network for hydro-powered cooling. With this tech-advanced bed, you can also monitor your body responds as you sleep to get insight on how to sleep more comfortably.

Also noteworthy is that this mattress has good bounce courtesy of its spring plus dense foam core. So, if you are an active sleeper, you might find it easier to toss and turn on this bed compared to strict memory foam mattresses. Then again, with the Eight Pod 3 mattress, you can customize the feel of the mattress to fit the condition you want to sleep in at a given time.

Best Under $1,000 - Nectar

Nectar Memory Foam Mattress

Check Current Price Read our detailed review

Highlights

  • quality components and reasonable price, offers good value for money;
  • quilted cover for extra comfort (mimics the Euro-top feel);
  • gel-infused top layer for a cooling effect;
  • Tencel cover for better air circulation;
  • great motion isolation, suited for couples and restless sleepers.

Finding an affordable King bed might be really hard sometimes, as this size is typically the most expensive. That’s why I’ve included the Nectar in my review of the best King size mattresses. 

This is a memory foam mattress with a medium feel, so it could make a great pick for side and back sleepers. Also, memory foam can absorb motion very well, which is a plus for couples or restless sleepers.

Those who suffer from different kinds of pain will also benefit from the Nectar. The layer of gel-infused memory foam offers a great amount of contouring without trapping too much heat. So, you can expect a refreshing sleep without tension and stiffness.

Speaking of edge support, the Nectar has surprisingly sturdy edges and offers a uniform surface. This might be an advantage if you share a bed with someone or just love sleeping closer to the edge.

I can easily recommend the Nectar as an affordable mattress that is no worse than more expensive brands. It can satisfy most types of sleepers, offering a cool and peaceful slumber.

Best for People with Back Pain — Amerisleep AS3

Amerisleep AS3

Highlights

  • breathable open-cell foam for cooler sleep without giving up close conforming;
  • plant-based foam to accommodate even sensitive and allergy-prone sleepers;
  • longer warranty to ensure reliable performance;
  • universally comfortable medium feel to satisfy more types of sleepers;
  • quality construction and sturdy feel, promises durability in use and won’t develop sags too soon.

Allow me to introduce another model that could be your best King-size mattress - the AS3 by Amerisleep. This mattress has a lot to offer, but the best feature is its ability to relieve back pain. The thing is, the AS3 conforms to the body and makes the pressure spread out evenly. Additionally, it has a zoned transition layer that ensures the back remains neutral throughout the night, alleviating pressure even further. And zero tension usually leads to less back pain.

You might also like the fact that the AS3 mattress uses plant-based Bio-Pur foam. This material is safer and contains fewer VOCs than traditional memory foam. As proof of that, my AS3 came without any harsh off-gassing. Plus, the Bio-Pur foam is more resistant to such allergens as dust mites and mold. This makes the mattress safer for allergy-prone sleepers.

Up next on our list of the best King-size mattresses to buy in 2022 is this high-quality product from WinkBed. The WinkBed king-size mattress combines both durability and comfort as its main features. This model feels sturdy and even rigid, which means it should serve you loyally for years to come. And it gets better: the WinkBed can be a perfect solution for overweight individuals. After all, it can be challenging to find the right level of support for larger people without ending up with a brick-wall-firm mattress. Luckily, the WinkBed has a firmer Plus version. It can accommodate heavy sleepers, keeping their spines neutral and preventing tension build-up.

Best for Side Sleepers — Zoma

Zoma Mattress

Click the button below to check current price

Highlights

  • slow response to pressure for effective motion isolation;
  • zoned comfort layer for pinpoint tension relief;
  • gel particles to aid thermoregulation during the night.

Being among the best King-size mattresses, the Zoma has a lot to offer. It’s a zoned memory foam mattress, so it excels at redistributing the weight evenly, aiding tension alleviation and fast relaxation.  

The Zoma performs especially well for side sleepers. This mattress offers a deep, gentle hug, enveloping the protruding body parts and reducing tension. At the same time, the Zoma keeps the spine aligned properly, making sure sleepers don’t experience any back pain. As a side sleeper who sits a lot in front of the computer and suffers from back tension, I can attest to this mattress’s comfort. It made my back feel perfectly relaxed while being gentle on my shoulder and hip.

That being said, the Zoma does not allow for much motion transfer. Therefore, it won’t let you disturb your partner when moving in bed. My wife (a light sleeper) and I (a combo sleeper) can confirm that.

How Did King Size Beds Appear on the Market?

Before we dive into details, let me allocate one paragraph of my King mattress review to a brief historical reference on how King beds actually appeared.

Because it’s quite interesting. 

Until the late 1950s, there were two most common bed sizes on the market: Twin and Full. The Hollywood shows and movies of that era projected strict views on intimate relationships, which dictated that it was normal for married couples to sleep in separate beds.

Ironically, a couple of years later, the same Hollywood shows and movies that portrayed the life of the rich changed the game completely.

The image of a luxurious bedroom with a huge bed tucked with silk sheets slowly transferred from the screens to the minds of regular users. This resulted in increased demand for larger beds, with the following introduction of Queen and King-sized beds to the market. The companies that pioneered in making these sizes were Sealy and Simmons (the latter also introduced the California King mattress a couple of years later).

Fun fact: Some historians suggest that the very first King bed was invented around the 1890s and was enormously huge compared to the modern King mattresses. It could easily accommodate up to 15 people (1). Imagine the size of the room you’d need to fit this bed!

Benefits of Having a King-Sized Mattress

Now, let’s outline how a good King-sized mattress can change your sleeping routine so that you make sure you’ve picked the right size:

  • More space. Obviously, you’ll have more personal space on a King mattress. This will help you get cozier and find a comfortable position to drift off more easily. Along with that, if you allow your pets to sleep on the bed — or, if you occasionally co-sleep with your kid — a few extra inches of space will also be beneficial.
  • Better support. The bigger area of a King-sized mattress allows for more even weight distribution. For example, if your partner is a large sleeper, you won’t feel how deep he dives into the mattress layers and your sleep will be uninterrupted.
  • Lower motion transfer. Due to the larger area, King mattresses also muffle sharp movements more efficiently than Queen ones. This might be an advantage for restless sleepers and their partners.
  • Healthier sleep. Overall, by having more room to move and get comfy, you can easily improve your sleep quality and even alleviate your sleep disturbances (assuming they were caused by a lack of space).

Aside from all of that, it would be unfair not to mention how luxurious a King mattress looks in a master bedroom. If you choose a high-profile bed and properly decorate it, you can easily turn your bedroom into the royal chambers.

Important Checks to Make Before Choosing a King Size Mattress for Your Bedroom

Finally, I want to briefly walk you through the little yet important details you need to consider if you want to choose the best King mattress on the market.

Here they are.

Room Space

A large mattress requires a lot of space to fit in properly. A King bed measures roughly 6 x 6.8 feet, and you need at least 2 feet more on each side to be able to get in and out of bed comfortably.

Add to this how much the pieces of furniture, such as nightstands and drawers, and the space between them will take — and you will see that not every room will be able to accommodate a King mattress.

I recommend that you opt for this size only if your bedroom measures at least 13 x 13 feet (2). In this case, you can comfortably lay out your King mattress along with the rest of the furniture, without making a room look crowded.

Also, be attentive when making a purchase. Make sure you’re buying a standard King (which measures 76 x 80 inches) and not the wider Cal King (which is 72 x 84 inches) (3).

Bed-in-a-Box or Regular Mattress?

Another problematic moment with King mattresses is their weight and bulkiness, which can make transportation difficult. Especially if you choose brands like Saatva, who don’t ship their products compressed in a box. In a house with narrow staircases, with a bedroom located on the second floor, mattress delivery can turn into a challenge.

So, a bed-in-a-box might be a more suitable option here. However, compressed mattresses might not always expand completely, especially the cheaper ones. This may result in insufficient support and decreased durability.

Bottom line?

Read user reviews and choose trusted brands with a good history and reputation on the market. Also, steer clear of suspiciously low prices.

Alternatively, you may consider ordering a Split King configuration. This way your mattress will arrive as two separate halves. Moreover, you may be able to customize each half prior to purchasing.

How Will You Use It?

Your lifestyle may also impact mattress characteristics. 

For example, if you and your partner live minimalist lives, you may not need to overpay for a luxurious King mattress. A medium-priced bed without any bells and whistles can work fine for you.

Keep in mind that as many as 21% of King mattresses range between $600 and $899, according to the statistics in 2016 (4). This means there are many decent models even for a more modest budget.

If your pets sleep with you, then you might need something more durable and resistant to their claws. In this case, investing in a mattress with a removable and washable cover is a good idea. Also, make sure your mattress is made of heavy-duty materials.

Warranty and Returns

Since King mattresses are the priciest option on the market, it’s totally okay to want some funds  protection. Choose companies offering sleep trial. In this case, if your new mattress appears unsuitable for your needs after the break-in period, you can just fill in the return claim and get your money back.

Also, learn about warranty conditions. Most mattress brands offer you a refund or replacement in the case of craftsmanship defects, but it’s always better to double-check.

Note that any spills and stains on your mattress will void the warranty, so it’s better to purchase a waterproof protector along with the mattress.

Price

Overall, larger mattresses usually cost more.

And since the King size is pretty big, shoppers might expect to spend quite a lot on their new mattress.

Now, on average, King mattress prices range from around $900 to $2,000. However, the final price would depend on the mattress type (aside from other factors such as brand reputation or warranty). 

Innerspring models tend to be among the cheapest ones. Foam mattresses belong to a more affordable segment, but there are plenty of high-end models among them as well. Hybrids are usually a bit pricier. As for latex mattresses, this type belongs to the most expensive price category.

What Is the Best Type of King Mattresses?

Each mattress type has its unique characteristics. Naturally, they might not work for everyone. That’s why understanding what each mattress type has to offer makes shopping much easier.

So, here are the main types of King-size mattresses available on the market these days:

  • Memory foam. Memory foam mattresses are famous for their pressure-relieving abilities. They conform closely to the body and provide adaptive support. Memory foam works well for partnered sleepers as it doesn’t allow for motion transfer. That being said, foam is notorious for sleeping hot. To avoid that, shoppers can look for models that use open-cell or gel-infused foam (at least among the comfort layers). 
  • Polyfoam. There’s not much difference between memory and polyurethane foam. However, the latter is a bit more responsive and doesn’t feel that restricting. Plus, polyfoam tends to be slightly less durable.
  • Innerspring. Spring mattresses offer bouncy support but aren’t ideal for pressure alleviation. They usually have only a thin layer of padding that might not work for some users (especially side sleepers). At the same time, innerspring models are affordable and sleep cool.
  • Hybrid. Hybrid mattresses manage to effectively combine support with tension alleviation. They use wrapped coils and foam/latex, making this mattress type ideal for someone who wants to find that golden middle. But hybrids aren’t perfect, as they tend to be thick and bulky. Plus, this isn’t the most budget-friendly option on the market.
  • Latex. Latex mattresses are especially popular among fans of natural products, as this type does not use harmful chemicals during manufacturing. Latex mattresses are bouncy but adaptive. This means they can provide close conforming and tension redistribution but don’t feel enveloping. Latex is also a temperature-neutral material (great news for hot sleepers!). However, shoppers need to keep in mind that latex mattresses can be very pricey.
  • Mattress type. Each mattress type has its peculiarities, and some might not work for you. So it’s better to learn a bit more about them before shopping. For example, foam models are famous for their pressure-alleviating properties. That being said, they tend to cause heat retention and might also restrict one’s movement. Innerspring mattresses sleep cool but don’t have an impressively long lifespan. Hybrid mattresses usually have a very balanced feel (support + cradling) and don’t sleep hot. They also have sturdy edges, in most cases. However, keep in mind that hybrid mattresses can often be pretty bulky and thick, which makes them harder to transport. As for latex mattresses, they are durable, sleep cool, and show great results in terms of pressure relief. This mattress type also has an above-average lifespan, which may explain the higher price point.

Other Factors That Make a Good King Size Mattress

Size doesn’t mean everything when it comes to mattresses. After all, the best King-size mattress is the one that meets your needs, not only offers more sleeping space. So, consider a few more aspects before you make your final choice to make sure you get exactly what you need:

  • Firmness and your sleeping style. A good mattress has to suit your preferred sleep position. Now, as a rule of thumb, most back sleepers feel the best using medium or medium-firm mattresses. People who enjoy sleeping on one side are advised to go with softer mattresses. And strict stomach sleepers should choose firmer mattresses that can deliver sturdy support. A quick note: these are suggestions for average individuals. If you are a lightweight sleeper (less than 130 pounds), you might want to go a tad softer for each sleep position to prevent developing sharp pressure points. And if you are heavier than average (above 230 pounds), you can try going one step firmer for each sleeping style to receive adequate support.
  • Thermoregulation. A bigger King mattress will create more space between you and your partner, which means there will be less heat accumulation. However, that might not be of any help if the mattress material would cause you to sweat. If you are prone to overheating at night, check out hybrid or latex mattresses. If you prefer foam, look for models that use gel particles for cooling or have a breathable open cell structure.
  • Edge support. A King mattress might offer you more than enough sleeping space, but it doesn’t mean you should disregard edge support. In some cases, stronger edges may really come in handy. For example, if your bed frame is low to the ground, you might require pressing into the mattress edge to give yourself a little boost and get up. The same rule applies to back pain sufferers who also need extra support when getting up.

F.A.Q.

How to get a King-size mattress upstairs?

Most mattresses are shipped vacuum-sealed in a box, so you just need to carry it upstairs and unbox it right in your bedroom. If your King mattress is delivered in its full size, you should measure the passages and staircases to make sure it will fit through.

How much does a King mattress weigh?

Depending on the materials used, a King bed may weigh from 100 to 180 pounds. But the thinner it is, the less it will weigh.

How to dispose of your old King-size mattress?

Many mattress companies offer free mattress removal when you purchase a new bed from them. You can also donate it to your local charity or contact a recycling facility in your area.

Conclusion

King mattresses are popular for a reason. They give you more space to stretch, which is especially important if you share a bed with someone who sleeps in a starfish position. I’ve collected five models that can please even the pickiest sleepers. They have excellent value for money and can offer you great support and serve for years to come.

Personally, I would recommend the Puffy Lux Mattress for your king-size mattress needs, and for good reasons. The major reason being the comfy foam feel it delivers while maintaining good support. I particularly love this mattress for its pressure relief and good airflow. It works for most types of sleepers, especially side sleepers who need good cradling at their pressure points. Overall, I think you will appreciate the balanced feel of the Puffy Lux mattress above all else.

So, why are you considering getting a King-sized bed? Does any model of those above seem suitable for you? You’re welcome to share in the comments below!
