I just removed the springs and the nylon material. I then cut pieces of luan (a thin, cheap plywood) to fit the metal frame and screwed them right to the metal frame. I left a gap at the spot where the bed frame bends so that the power lift head and the storage access works as before. We bought a California King SC mattress. It's a few inches longer than the original mattress, but when we bring the slides we just let the air out and the mattress just colapses with no problem.
