We put an I-Comfort memory foam thick mattress on our 2015 FBTS without problems. The only issue we have found is that it is much heavier when lifting the bed to get to the storage compartment and does not stay up on its own. We are thinking of getting a stronger hinge but haven't done that yet. Anyone have suggestions???
