A folding memory foam mattress is much more comfortable for sleeping, especially for adults. Memory foam is denser than polyurethane foam and will provide better support. A folding mattress with dense foam will also last longer and won’t sink to the floor when a lot of weight is put on it.
Milliard's Tri-Fold Foam Mattress is nice for a few reasons. First and foremost: friends who need to crash. The mattress is padded with 4-1/2" of high density foam that's not much less comfortable than your standard sleep chamber's setup. It's also ultralight, and the queen size folds down to 58" x 29" x 14" for easy transport and use while road tripping or car camping.
The mattress is a very comfortable folding foam mattress. Four inches of dense foam make this mattress comfortable for adults to sleep on. The LUCID 4-Inch Folding Mattress easily supports your weight without sinking down to the floor.
