It's very heavy and too big for the futon.  It's constantly slipping off.  It's also very hard, not cushy at all like the picture would suggest.  I had to buy a gel memory foam mattress topper to make it usable.  I wish I had bought a sleep sofa instead.  By the time I added up all the extra costs including the cost of the futon frame and the topper, I could have had a decent sleep sofa and it would have looked a lot nicer.
