MATTRESS SIZING

Choosing the mattress size that is right for you is just as important as choosing your mattress comfort and construction.

Your current needs, living space and sleeping arrangement will play a role in whether you choose a Full over a Queen bed, while knowing of future plans might play a role in whether you choose a King-sized bed versus a Queen size.

No matter your situation we know that one size definitely doesn’t fit all when it comes to a bed, so consider the information below as your own personal comfort and mattress sizes guide that is here to help you find your perfect fit.

Before we get into the nitty gritty of the advantages of each individual sized mattress, here’s a US bed size chart to get your started. We broke it down by inches, square inches and even square feet so you can compare them to how much space you have.
