Full-size Foldable Memory Foam Mattress 2.5 inches thick. This mattress is foldable into thirds, which makes it much more portable than normal memory foam mattresses. You can move it and put it away in a closet easily. You can use it to make any normal spring-mattress bed incredibly comfortable, or use it as a standalone mattress on a bed frame. Even if you just put it on the ground, it is very comfortable. Perfect for using it as an extra bed when you have company staying over. The mattress is contained in a washable cover, so the memory foam is never exposed. Bought a year ago in South Korea Hyundai Shopping mall in Seoul for a little more than $250USD. I am moving to the US so I can't take it with me, although I wish I could. Once you start sleeping on memory foam, you won't be able to live without one. A moving sale price of 300rmb
