Queen Sofa Mattress Dimensions

This 4-inch gel memory foam mattress measures 72 by 58 inches and fits standard queen-size sofa beds. The medium-firm feel suits both everyday seating and overnight guests. It ships compressed and rolled for simple handling.

Certified Foam and Washable Cover

CertiPUR-US and OEKO-TEX certifications confirm low-emission materials and safer textile production. The removable polyester cover zips off for machine washing. A 0.5-inch gel layer sits above a 3.5-inch high-resilience base to balance cooling and support.

Folding Design for Compact Spaces

The mattress folds into the sofa frame, making it practical for guest rooms, RVs, and boats where storage is limited. Buyers needing a thicker permanent bed or a non-folding platform mattress should consider other options.

Questions about this item

How long does the cover last before it needs replacing?

The removable polyester cover is machine washable with mild detergent and air dried, so regular cleaning extends its life instead of requiring scheduled replacement.

What stops the mattress from expanding fully after unboxing?

The vacuum packed roll needs 48 to 72 hours to reach the full 4 inch thickness; cooler rooms or compressed storage can slow the final expansion.

Does the gel layer keep the surface cool during overnight use?

The .5 inch gel infused memory foam top layer is designed to regulate temperature and provide pressure relief throughout the night.
