Reviewing 13-Inch King-Size Mattresses


Our review process

No more reading through dozens of confusing articles to try to figure out which 13-inch king-size mattress to get! By reading this article, you'll have an excellent understanding of what kinds of mattresses are on the market, so you can confidently purchase a mattress that will ensure comfortable sleep for years to come.

Before buying a 13-inch king-size mattress, you'll want to know what you should take into consideration. These king-size mattresses measure 76" X 80" and are perfect for master bedrooms. They are designed to spaciously fit couples, offering plenty of space for you to spread out. However, they are not ideal for areas with limited room, since they can make the area look even smaller. In addition, they are large and heavy, making them difficult to transport and flip.

13-inch mattresses are less likely to sag, so the surface will remain flat to ensure adequate support over time. They are built with a sturdy construction, making them more durable and able to sustain more weight. These 13-inch mattresses are suitable to use with standard-size sheets, so it will be easy to find linens that fit properly. However, they are higher off the ground than thinner mattresses, so getting into and out of bed is harder than it would be with a mattress that is thinner.
