I purchased this 4-inch foam floor mattress for when grandchildren stay over. This is my 2nd one, since zi have 2 grandchildren. I don't have room for beds or bunk beds, but I have a space where I can store these. I slept on it myself several nights in a row when I had company and I found it to be much better than sleeping on an air bed. I purchased mattress covers and fitted sheets that fit the exact dimensions of the mattress and I am happy to be able to provide a perfect sleeping setup for my 2 grandchildren! If you have a place to store the mattress when it's folded (25 inches high, 31 inches wide, 12 inches deep) I recommend a 4-inch thick foam floor mattress over an air bed. In my home it is the perfect solution! Follow all the directions for allowing the mattress to reach its full thickness. It is vacuum packed and needs several hours (almost 2 days) to expand.

Blow up beds are better

Color: Grey, Size: Queen

Blow up beds are better. These are barely thicker than a sleeping bag.
