The ZzZ-Chest comes with an 8-inch bi-fold innerspring mattress. This is a one sided mattress. The padding is on the top and there is a split on the bottom that allows the mattress to fold and unfold easily.
The innerspring construction gives the mattress enough rigidity to stay up right when in the closed position. When open the innerspring mattress will have a firm feel as it is on a solid sleeping platform. Off white tick with tufting. Standard sheet sizes, twin, full or queen will fit on the mattress that comes with the ZzZ-Chest or Studio cabinet bed.
The original Fu-Chest holds an 8 inch futon. See the Original Fu-Chest page for futon and mattress options.
