Review on 🛏️ Zinus Gel Memory Foam Tri-Fold Floor Mat: Portable Folding Comfort, Narrow Twin Size by Alicia Jones

. Cot mattress (can also be used on the floor if you don't have a cot). I put mine on my Coleman ComfortSmart camp bed. This makes the crib 75 inches long (the same length as a twin or full-size mattress, although narrower). And it's very comfortable. It is good for camping or overnight stay at home. When folded, it easily fits in the trunk of a car. I like that it's not too heavy and fits in the Milliard Tri-Fold Mattress (31")" tote bag (see my other review). A great purchase if you are camping, staying overnight or want to bring your own bed when traveling to visit friends and family. After unpacking, it takes about two hours to fully fluff. Allow it to fluff up completely before folding or attempting to lie on it. When you first open the packaging, the usual memory foam smell is present, but if you leave it open for a few days to air out, the smell dissipates fairly quickly. I find that walking on the mattress (with clean socks) helps force fresh air through the mattress.
