Twin Size Mattresses

Twin size mattresses are the smallest, and coziest, mattress size on the market, but we still manage to pack a lot of high-quality comfort and support into this 38” x 75” sleep space. Twin size mattresses tend to be more affordable due to their smaller size, but they can be a practical option for most sleep needs.

Buying a Foundation for a Twin Size Bed

Create a more supportive sleeping experience by pairing your twin size mattress with a twin 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 two options compatible with a twin mattress: a slatted foundation and a platform foundation.

Clever Connect™

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.

Platform BedInABox®

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.

Frequently Asked Questions

What is the standard size of a twin bed mattress?

What is the difference between a twin and a twin XL?

Twin and twin XL mattresses are comparable in size, with the twin XL size measuring just 5 inches longer. The twin XL comes in at 38 x 80 inches, giving you those 5 additional inches of length. Both size are still great options for children, single individuals and smaller sleeping spaces.

Can an adult sleep in a twin bed?

While there is not much space for an adult to spread out or roll around in a twin bed, they can certainly sleep in one comfortably if it suits their sleep needs. If you are looking for the convenience and affordability of a twin mattress, but require more sleep space, a twin XL or a full size mattress may be a better option.

How many BedInABox® mattresses come in the twin size?

Five of our six mattress models are available in the twin size. These include the Essential, Original, Tranquillium®, Azul®, and Dual Hybrid® mattresses. The Eco-Lux® mattress is our most premium mattress construction and is only available in limited sizes.

What size room do you need to for a twin mattress?

It is recommended that your room has an area of at least 70 square feet, or measures 7 feet by 10 feet, to comfortably accommodate a twin mattress. This room size will allow you space to fit your twin bed with additional furniture while maintaining adequate walking space.
