family playing on mattress

Are you looking for the best King size mattress because you know that size does matter? If you share your bed with your kids or pets or just you and your partner are restless movers tossing around all night, you will need a big mattress. In these cases, a Queen size bed will be scarce, and you should size up and invest in a King size mattress. But which one? Buying such a big mattress could cost a more significant amount of money, so I would like to help you make the best decision and find the best King size mattress that fulfills your needs.

I’m going to show you the best King size mattress choices of excellent brands and types. You will find options for memory foam, latex, coil, and hybrid mattresses, together with some guidance to make a well-founded purchase decision.

Memory Foam mattresses

Foam mattresses are the new generation of modern mattresses. However, manufacturers have used several types of foams for decades now. You might know, but memory foam was invented by NASA in the 60s and not for sleeping or comfort but for safety reasons. They used it for seat cushions to save pilots in case of crashes. Shortly everyone realized that this material could incredibly increase the comfort factor of mattresses. So today, you can hardly find a mattress manufacturer who doesn’t use this material. This material reflects slowly on movements and provides a hugging and well contouring feel since you sink into the mattress instead of lying on the top of it. It gets back its original form slowly after the pressure is released. Memory foam shows its great benefits in pressure relief and supports side sleeping positions very well.

Pros and Cons of memory foam

ProsCons
Provide support for the entire body
Excellent motion isolation
Long lifespan
Excellent pressure relief attributes
Resistant to dust mites
Noiseless
Trap air that can lead to overheating
Less responsive
Weak edge support
The sinking feeling is not for everyone
Quite expensive

Our Picks – Best King Size Memory Foam Mattresses

Now you are familiar with the benefits and drawbacks of a memory foam type mattress. If you still want to get the best KIng size mattress, the next challenge is picking one from the endless selection of available options.

Amerisleep – AS4 Memory Foam Mattress

Amerisleep offers a wide variety of sleeping products besides pillows, bases, bedding accessories, mattresses, and toppers that are the brand’s main products. I picked an excellent plant-made plush memory foam mattress with a nice cooling effect and a unique quick reaction attribute from the quite broad mattress selection. Model AS4 is made with a thicker comfort layer that makes it an excellent option for side and combo sleepers.

The mattress comfort layer and a particular pressure relief layer are placed on a durable base foam with a long lifespan and solid support. The comfort layer is made of a unique open-cell plant-based BioPur foam. The open cells wick away moisture and trapped air efficiently and prevent overheating. Are you afraid of memory foam because you feel trapped and miss the bouncy feel? This special foam offers a great solution because it responds rapidly to movements. Its magic is responsiveness.

A targeted pressure relief system keeps the perfect spine alignment between the responsive comfort layer and the durable base. Perfect spine alignment is essential to say goodbye to painful mornings. All the layers are wrapped in an ultra-breathable cover that promotes all the vital attributes of the foams. 

You can choose between seven sizes and enjoy the 100 nights trial. Another advantage that we can’t skip is the complete lack of odor right after opening it. So if you are ultra-sensitive to smell, this plant-based foam can be an excellent choice.

Highlights:

  • Open-cell Bio Pur foam bounces back fast
  • Available in 7 sizes – the six most prevalent one and Splint King
  • Advanced foam to prevent overheating
  • It contains plant made odorless memory foam
  • Excellent pressure relief
  • Made in the USA

Bed In A Box – Azul

Bed In A Box was one of the first Bed-in-a-box brands and is still a leading company in the sector. Besides the memory foam and hybrid mattresses, the brand offers adjustable beds, foundations, and other essential sleep accessories. The brand has a great potential to offer the best King size mattress for you. 

The mattress, Azul, is a perfect pick to enter the memory foam mattress world and give a try to the feeling if you never did it before. The 120 day trial period guarantees you can’t lose much if you purchase this mattress. The price is manageable also, and Bed In A Box often comes up with great deals and offers.

Let’s have a look at Azul in a bit more detail. You can choose from a broad size palette from Twin up to California King size. The mattress is built up of three layers to provide you the perfect comfort, spine alignment, and pressure relief. All the mattress is wrapped in a soft knit cover. The CoalRest memory foam and the construction of the cover eliminate overheating so that if you were afraid of the disadvantage of memory foam with this mattress, you could avoid sweating.

The result makes Azul a medium soft mattress that still can provide excellent support. It will be perfect for you if you are a side or black sleeper with an average weight. Azul will let your shoulders and hips sink in the mattress enough to keep your spine aligned even if you sleep on your side.

Latex Mattresses

Traditionally latex is made of a white liquid extracted from the rubber trees. This liquid is harvested from the living tree. Water is removed during the manufacturing process, and the material remains perfect for various products, particularly for a mattress with a remarkable cooling factor and high responsiveness. Besides this natural option, synthetic versions also appeared on the market. Synthetic latex is a mixture of synthetic polymers and the extract of the rubber tree. This option is less expensive but less healthy also.

Different types of latex

There are two main ways producers create from the rubber tree: extract a latex foam, and as a result, they get Dunlop or Talalay latex foam. Manufacturers tend to say that their product is better, but the reality is that they are just different because of the manufacturing process. As a final result, there are some differences between the two latex foams, but not many:

  • Dunlop latex is denser than Talalay latex.
  • Producing Dunlop is more energy-efficient so that the final product can be cheaper.
  • Dunlop feels springy while Talalay is rather bouncy.

Pros&Cons of latex mattresses

ProsCons
Good responsiveness
Keep you cool
Impressive lifespan
Eco friendly and organic
Advanced body contouring without a “sinking” feeling
High average price
Heavy and difficult to move
Pure edge support

Our Picks – Best King Size Latex Mattresses

After this little catch-up on latex and latex mattress features, let’s see the online market’s best-rated options. Hopefully, you will find the best King size mattress you desire.

Plushbeds – The Botanical Bliss

Plushbeds offer a wide variety of mattresses, memory foam, hybrid, latex, and even RV mattresses are available in its online selection. I brought you to introduce a lovely organic latex mattress, the Botanical Bliss. All the ingredients are organic for this excellent mattress. Made by hand in the USA from GOLS certified organic latex, GOTS certified organic cotton, and GOTS certified organic wool.

This absolute toxin-free and hypoallergenic mattress are available in nine sizes, so I assume you couldn’t have a frame that won’t fit. It is available in medium or medium-firm versions to be excellent for all sleeping positions and every weight. Also, you can choose the height of the mattress that is perfect for design purposes but can also be a purse-friendly decision to go for thinner options. Remember, if you are a heavier sleeper, thickness is critical, so go for the 12 inches version rather than save a few pennies on the thinner option.

The size selection contains Split Queen, Split King, and Split California King options also. That is wonderful if you and your partner’s firmness level preferences are different. You can choose one medium and one medium-firm version with the same height to fulfill both needs. Split versions are also a wise decision if you need to move the mattress later on. Latex mattresses are heavy. For example, the 12 inches thick California King version is 221 lbs, so a divided version halves the burden you need to lift.

This mattress is a luxurious and carefully manufactured item from the first part until the last stitch. The 100 days trial period provides you a worry-free period till you can decide if this is the perfect choice for your needs. If not, you didn’t lose anything; the money-back guarantee keeps your investment secured.

Highlights:

  • Entirely organic
  • Medium and medium-firm versions are available
  • Nine sizes
  • Three thickness options: 9”, 10”, 12”
  • Compatible with an adjustable base
  • Handcrafted in the USA

Naturpedic – Eos Trilux Organic Mattress

Eos Trilux Organic Mattress of Naturpedic is a lookout to the world of absolute luxurious mattresses. It is elegant and sophisticated and offers such a luxurious feel that you can’t compare it to a mass product. 

The mattress is built up based on an exceptional idea that increases customization to a new level. The mattress got three each three inches layers of latex individually wrapped in cotton encasements. The variation of different firmnesses makes it possible to choose from five firmness versions from plush until extra-firm ones. Even more, at Queen, King, and California King sizes, the layers are split so you and your partner can choose other firmness but still have one mattress instead of two with a gap between them. There is a quilt with wool and PLA padding on the latex layers to keep the surface of the divided layers more unified. If you are unsatisfied with the result of the customization, the mattress setup makes it possible to change any layers within the trial period. 

The mattress got meaningful certifications, and it is guaranteed that it is free from toxins, chemicals, and odor. It is made by hand, and every piece is a result of caring craftsmanship. 

There are not too many cons regarding this exceptional product, maybe just its price. For this sophisticated and high-end item, you need to open your purse wide, but it will be an outstanding investment for your health. Another con, but it is valid for all latex mattresses, is the weight. The massive amount of latex makes this mattress heavy that can make fitting your sheet complicated. 

Highlights:

  • Made of organic wool, cotton, and latex
  • Five firmness options: Plush, Medium, Cushion-firm, Firm, Extra-firm
  • Available in the most prevalent six sizes
  • Independent firmness customization on both sides
  • Layer swap option for 90 days
  • Made in the USA

Is a latex mattress meant for you? Do not miss the selection of the best latex mattresses of the year!

Innerspring or iCoil mattresses

Innerspring mattresses are the father of modern mattresses. The name is from the metal support coils that build up an innerspring mattress’s core. These mattresses are the most frequently used ones and have been available since the early 1900s. However, I think all of us can recall memories of a pure metal bed frame with a so-called squeaky mattress inside it with metal coils and some padding; modern innerspring mattresses are different and much more comfortable. Often they come with additional layers of different types of foams while keeping the bouncy feeling of the coil mattresses. 

Innerspring mattress – Pros&Cons

ProsCons
Affordable price range
Excellent air circulation between the coils – cooler sleeping experience
Strong edges
Suitable for many sleep positions
Responsive – better for sex
Continuous coil mattresses have pure motion isolation
Shorter lifespan
Not good if you have joint pain
Coils can make some noise

Our Picks – Best King Size Innerspring Mattresses

If you prefer the old-fashioned way, check out these Coil mattresses to enjoy a familiar feel during your nights. Innerspring mattresses are moving to a more acceptable price range. I will also show you a more luxurious version and a price-friendly choice to purchase the best King size mattress for your needs.

Keetsa – The Keetsa Plus

Keetsa is a well-known brand in the mattress industry and offers its products on a wide palette. You can find many choices for different types of mattresses, foundations, pillows, and bedding. Keetsa Plus is one of this broad product palette.

Keetsa interprets the Keetsa Plus as an honest, simple, but still intelligent product. It is honest because it’s built up from iCoils that offer a very familiar feel and comfort you might already know. There is a one-inch memory foam and an additional one-inch comfort foam padding on the top of the very firm and supporting iCoil core. The result is a firm mattress that will be perfect for supporting a stomach sleeping style. Some people can find the mattress comfortable even for back sleeping.

Keetsa got CertiPUR-US and Oeko-Tex certification and picked the used materials carefully. As a plus, they never use fiberglass as a fire barrier. For this purpose, they add a cotton fabric padding to the surface. Thanks to the iCoil core, the cotton cover, and the fiberfill padding, you won’t heat over and can sleep comfortably without freezing or sweating issues.

If you need a budget-friendly but still comfortable and durable option for your more comfortable nights buying The Keetsa Plus won’t be like purchasing a lucky bag. You will get what you paid for.

Highlights:

  • Two inches of memory foam and comfort padding
  • Firm mattress perfect for stomach sleepers
  • Available in five sizes
  • Temperature neutral construction
  • CertiPUR-US and Oeko-Tex certified
  • Made in China

Naturpedic – Chorus

As we already discussed, Naturpedic is a brand of luxurious handmade products, and one of these unique items is the Chorus mattress. Chorus is an innerspring mattress but provides a lot more than a simple budget Coil mattress could. After opening the box, you will first see the superior design and soft and sophisticated cover materials. 

Like all components of the mattress, the covering quilt is organic as well. The padding is made from organic wool, and PLA covered with organic cotton. (PLA is a planted-based synthetic fiber created for improved moisture-wicking and durability.) The core of the mattress is the eight inches iCoil layer. To avoid the lack of pressure relief that is a drawback of innerspring mattresses, Chorus contains a one-and-a-half-inch microcoil layer. Microcoils provide advanced motion isolation and full-body-contouring comfort.

Thanks to the coils and fiber padding, the mattress is temperature neutral and will keep you in perfect comfort all night long. You can sleep confidently on this mattress because it is free from chemicals and is entirely organic. It is a medium mattress that can be comfortable for everyone and any sleeping style.

Highlights:

  • Organic mattress
  • Besides iCoils additional microcoils for enhanced comfort
  • Available in the six most prevalent sizes
  • Temperature neutral construction
  • Medium comfort supports all sleeping positions
  • Made in the USA

Hybrid mattresses 

Hybrid mattresses are combining innerspring mattresses and foam mattresses. They have an innerspring support layer and a 2-3 inch thick memory or latex foam comfort layer on the top. They tend to be an ideal combination of solid support and a hugging, cozy feel. 

By definition, a hybrid mattress is at least 2 inches of memory foam layer combined with a pocket coil supportive core.

Hybrid mattress – Pros&Cons

ProsCons
Strong edge support
Good responsiveness
Less sinking feel than pure memory foam
Advanced pressure relief combined with efficient support
Better air circulation than pure foam mattresses can provide
High price
A shorter lifespan
Potentially not noiseless
Memory foam versions still can retain heat
Not as efficient motion isolation as pure foam mattresses has

Our Picks – Best King Size Hybrid Mattresses 

After this little lecture about hybrid mattresses’ characteristics, you can decide if they are meant for you or not. If you still want to buy a hybrid mattress to get the best King size mattress, grab a cup of tea or coffee and give yourself a few minutes to review these excellent choices.

Zoma – Hybrid

Zoma released a fantastic mattress that athletes frequently use. They don’t handle it as a secret and can easily find the names on their website if you are interested. Zoma works with high-quality memory foam and other foams, creating a hybrid solution for proper spine alignment, improved edge support, and better motion isolation.

This hybrid is available in one firmness that is a just-right medium one, so it is perfect for combo and back sleepers. If you like the idea of firm but still bouncy support of coils but need the hugging feel of memory foam, this mattress can provide you both. Great plus that, as Zoma says, the so-called Reactive layer between the wrapped coils and memory foam comfort layer can prevent the sinking feel of regular memory foam mattresses. 

Hybrid mattresses usually work great for warm sleepers because of the proper air circulation. This mattress keeps this advantage despite the memory foam layer. The memory foam is infused with cooling gel and perforated to lead the air to the coils.

However, the mattress is not organic but CertPUR-US certified, so you can be sure that it is free from formaldehyde, ozone depleters, heavy metal, and fire retardants. 

Zoma offers you complete solutions with a foundation or with an adjustable base to give the necessary support for your new mattress.

Highlights:

  • Memory foam and foam hybrid mattress
  • Seven sizes
  • Advanced pressure-relief attributes
  • Improved air circulation by the breathable cover and cooling perforations
  • Made in the USA
