This item seems to be a well-made futon mattress.  It fairly easily bent at the hinge, although we did have to stand it up, bend it, then put it on the frame.  The mattress appears comfortable but it has not been tested yet as the futon is a guest bed.  Shipping was efficient and packaging was good.  Looking at the box it was hard to believe it contained a mattress of this size, but once "released" from its bindings, it quickly opened to its size.  There is a minor new item smell, but it is not overwhelming and hopefully will fade with time and use.
