I have this futon mattress for about two weeks now.  This blows away the old mattress on the futon.  Mind you the old one was close to 20 years old! This one is about 3 times as thick as the old one.  It forms itself into the contours of the futon frame.  I keep my futon as a sofa and use it every single day.  The plushness of this futon mattress cannot be beat! You will not be disappointed!
