Breathability, motion isolation and firmness will also be dependent on these characteristics, so think about what is comfortable and cozy to you and then start your search.

An Introduction to King Size Mattress

What are King Sized Beds?

Beds that measure 76 inches in width and 80 inches in length are called king-sized. The benefits of these products are numerous, with the most important one being a lot of space. With the mattress of these proportions, you and your partner or a pet can enjoy uninterrupted sleep with ample space to stretch out. These features are especially useful for taller people who will have sufficient legroom.

However, if you are looking for even more space for your legs then perhaps you should opt for California king size. A variation to king, these mattresses are slightly narrower, with a width of 72 inches but the length of 84 inches.

Types of King Size Mattress


Durability and comfort are the two main traits of latex mattresses. Their core is filled with latex foam, which is not only breathable but also responsive, hence the rising popularity of them. The synthetic latex will make this product even more durable.

Memory Foam

Does the bed that molds according to your body shape sound like a dream-come-true? If that is the case, look for a memory foam mattress whose main characteristic is the superior comfort it provides. The dense and heavy viscoelastic core will support your body and absorb the motion transfer.


Looking for a bouncy effect? Then you should probably check innerspring mattresses which offer precisely this. The metallic coils are the key ingredient here. The thinner coils provide less firmness but contour to your body. The thicker ones, on the other hand, are firmer and give better support. Some will also have coils that are individually wrapped which help motion isolation.


And if you were reading and thinking, well, I want both the bouncy effect and body contouring, then perhaps you should go with the hybrid mattress. These beds provide you with the plush body-forming surface of memory foam and the sufficient support and bounciness of the coils.

Are there Affordable High-Quality Options?

Although you might think that these mattresses are expensive due to their substantial dimensions, the truth is that you can easily find affordable solutions of this size. Many of these economical mattresses will be either with memory foam or hybrid, combining foam and innerspring coil.

Don’t worry about being on a tight budget; you’ll easily be able to find the inexpensive king-size bed that will fulfill your needs.

What are the Benefits?

Provides Comfort and Extra Space
