4-Inch Tri-Folding Mattress Topper

It uses a modular zipper system and folds into three sections, so it can lie flat on a bed as a 4-inch topper or fold into a compact block for use as a floor mat, guest bed, or seat.

It is 4 inches thick and comes in Single, Twin, Twin XL, Full, and Queen. As an example, the Queen measures 60 x 80 x 4 inches flat and folds down to about 60 x 27 x 12 inches for storage.

No. The topper is designed to be noiseless and virtually odorless, so it is comfortable for everyday sleep as well as occasional use.

It ships free within the U.S., comes with a 100-night risk-free trial, and is backed by a 10-year warranty.
