I have a sleep number and I hate it. I like a very firm bed and the lady likes it soft so my side is always more elevated because of more air than hers. It makes me constantly roll to the center of the bed like sleeping on a hill and the center of the bed has a gap between the air bladders and makes me sleep like shit.

Sleep number is just an overpriced air mattress IMO, and I'd rather just sleep on the couch anyway.
