Be sure and get a nice firm mattress whatever brand you choose. Since you can't use a box spring with a hospital bed, it's going to be much softer. Tom has a hospital bed and I have a twin right next to his. Even though we have the same exact mattress his is quite a bit softer. His tends to "bottom out" and sag in the middle. Even when he could still turn over by himself it was hard for him to do it in that bed. Lots of people like memory foam, but we haven't tried it.
