Which Mattress Size is Right for You?

Download our Mattress Size Chart so you can be sure the mattress you buy will be the perfect fit for your space.

Buying a new mattress, whether it is your first time or your fifth, is a big decision that is often accompanied by other major milestones in life’s journey. Are you or a loved one starting college and need a mattress to fit into a dorm room? Did you just close on a house and need a new mattress to complement your new space? Are your children transitioning out of their smaller beds and are ready to upgrade to something larger? Or are you simply tired of tossing and turning on your old mattress and need to experience something different? Look no further! BedInABox’s mattresses, coming in six different sizes and always made right here in the U.S.A., will deliver quality sleep right to your door, making this critical life decision easier than it has ever been.

Here at BedInABox, we know that while finding the perfect match is exciting, it can also be stressful or overwhelming. As such, we want to eliminate any risk that you feel may be associated with purchasing your new mattress. After your new BedInABox mattress is delivered to your door, within 2-5 days of purchase in the contiguous United States, we want to give you a full 60 days to try it out, totally risk-free. We think you will love it, and you can sleep well knowing that all of our mattresses have a 20-year warranty. After the 60th day, if you are still not completely satisfied with your new mattress, you can call us to let us know. You will receive a Return Merchandise Authorization (RMA) number, and the team at BedInABox will begin processing your mattress return. Please take the full 60 days to get used to your new mattress, and if you are not satisfied, we will issue RMA numbers from the 60th day to the 120th day. We will never charge customers returning their mattresses a restocking fee or a reshipping fee.

In the fall of 2004, a foam expert, a digital marketer and a machine builder with a wild idea got together in Johnson City, Tennessee to discuss the concept of putting a queen size mattress into a box that the freight companies would accept. Eighteen months later an industry was born from the imagination and leadership of Bill Bradley, the creator of that first machine used to put a BedInABox! Yep… Johnson City, Tennessee, made in the USA from day one!
