Hate beds - They are rarely 'right'. Gave up on em, use my couch and three pillows. Works well. Well supported in the spine, held in comfortable position, knees against back of couch. Very nice indeed.
Hospital beds are pretty good. Otherwise the bed I slept in whilst visiting friends. Had a great really thick, well sprung mattress with an overlay of a tempurpedic 4" mattress. Now that was a treat. Best bed ever.
