I love this futon mattress.  It’s thick -10 inches - and very comfortable.  It doesn’t take up a lot of room which is just what I wanted for my small apartment.  My little dogs LOVE it.  The frame is perfect!  It holds the 10 in mattress perfectly which is why I got it.  It also has small arms on either side which are necessary for me to support myself when I get up.  (Old body).
