I love this memory foam mattress. It is advertised as a “narrow twin” but was actually much bigger than a similar foam mattress which was advertised as “twin” size. The foam mattress was delivered in a compact box and rolled in an air tight bag. Once exposed to air, the mattress expanded to it’s full size. I plan to use it for sleepovers and for camping and I think they will be perfect for both. One thing I would love to see is some sort of clip or tie on the ends and a handle so that the mattress would be held together and wouldn’t flop around while carrying. Great product!
