I purchased this to replace my old sofa bed mattress which was too thin. Together w/ bunkie boards under the sagging springs, this mattress makes for a comfortable sofa bed. Of course, air mattress will never be as good as a real mattress, but the added thickness makes a big difference to our guest bed and I'm pleased that it can be folded into the sofa bed when not in use. Easy to inflate, no leaks so far.
