How to choose the right mattress size

Purchasing a new mattress is a huge decision — and one size definitely does not fit all. Before buying, it's important to figure out which bed is best for your sleeping habits and space.

You should consider your preferred sleeping position, height and weight, a partner, the number of pillows you use, and how much personal room you like. Also, you may want to consider adding extra room for pets or children jumping in the bed.

To help you choose the best bed size, see the list of mattress dimensions and descriptions below.
