What mattress size is right for you?

Choosing what size mattress to buy isn’t easy, especially considering the array of choices available. Mattress size is an individual preference, but understanding specific dimensions and your own expectations will help you narrow down the bed size that will serve your needs best. When you’re considering which bed size to buy, some factors to consider include whether or not you sleep with a spouse or partner, if children and pets share your bed, whether you’re on the taller or shorter side and how large your bedroom is. Record bedroom dimensions before you shop to give yourself an idea of the space you have, and do some research so you’ll feel confident when you’re ready to buy.
