MLILY Tri-Fold Memory Foam Mattress Topper, 4 inch Twin Folding Topper with Collapsible and Washable Cover, Travel and Guest Mat, 75"×38"×4", Grey

This is the most comfortable portable foam mattress. I like a firm mattress and this did not disappoint. I feel well supported and do not feel the floor at all. It’s a little bulky but there really isn’t a way to avoid that given what it is. It’s a full sized twin mattress size when unfolded. I’ve been able to fold the mattress up with the sheets and blanket on it and fit it folded into the provided carrying and storage case. Unfortunately the carrier case is a bit cheap and flimsy. Eventually the handle did tear. That’s my only disappointment. I think I would be willing to pay more for a better carrying case or if I had the option to buy a cover case that is made of better and more durable material.

What an amazing mat!!! It is super comfortable and it is asking good as my bed mattress, if not better! I am considering getting another one for if I have more than one guest over for the night because it is super comfortable!

Have been using on and off for few months now. Really comfortable. Best when you have guests or when kids decides to crash in your room, or sleepovers etc. Comes with a cover to store and foldable feature is a big plus.

Great portable mattress topper for kids. My toddler loves napping on the mattress and very easy to take on trips. Would recommend it. It is comfortable even for adults.

Mattress is fine and comfortable enough. It's what you'd expect for the price. The only reason I gave 4 instead of 5 is because the storage bag is very low quality. The storage bag ripped upon the first time use and is super thin.
