Also referred to as “double beds,” full size mattresses measure in at 54” wide by 75” long. Standard full beds maintain the same length as twin mattresses, but offer 16 inches of additional width. Slightly smaller than a queen, the BedInABox® full is great for smaller bedrooms, but still offers plenty of space to spread out.
A full size mattress is 54 inches wide by 75 inches long.
Single Sleepers
Full mattresses are perfect for solo sleepers. If you share your bed, you may want a larger mattress size.
Small Bedrooms
The full size bed is ideal for growing teens or young adults looking for more sleep space, but don't have the need for a larger mattress.
Your full size mattress in a box comes with a 120-night, risk-free sleep trial. If you don’t love your new BedInABox® after sleeping on it for 60 nights, let us know and we will get the return process started. Details can be found in our Return Policy.

Create a more supportive sleeping experience by pairing your full size mattress with a full size foundation. A mattress foundation serves as a base for your mattress and generally uses solid planks or slats to support and lift your mattress off the ground. There are different types of foundations suited to different mattresses and sleep preferences, BedInABox® currently offering three options compatible with a full mattress: a slatted foundation, a platform foundation and an adjustable foundation.
Provides simple, slatted support for memory foam or hybrid mattresses. This sturdy foundation is available in a 5” profile or an 8” profile and can be paired with optional foundation legs for additional height.
Best described as a combination of a standard mattress foundation and a decorative bed frame, our upholstered platform offers a slightly lower profile than pairing a solid foundation with a separate bed frame and is compatible with all BedInABox® mattresses.
A solid mattress base that can be raised or lowered to create a custom sleep experience. The MotionInABox™ 1.0 adjustable base comes with an easy-to-use remote and silent-drive motors for quiet, convenient comfort.
Our 9” Essential mattress is a simpler take on our Original Mattress, utilizing the same dual layer memory foam technology in a slightly thinner, medium-firm mattress profile.
