This futon mattress has a one piece foam core in the center. What this does is add uniformity to the overall shape of the mattress. It also adds strength when using it on a A-frame style of frame. This futon can be made anywhere from a 5" up to 9" thick.

The basis "Select" futon might just be all you need for that spare room  and occasional overnight guest. Still one of our best sellers and with a great price point. We have this priced from $118 up to $169 depending on the thickness.
