I never saw the sleep number thing other than huge commissions for the sales folks in dedicated stores. The board thing in the middle was a no brainer that it wasn't going to happen for us. Three of us share the bed. The dog in the middle.......he might get grumpy.From my research- Sleep number is a pair of adjustable air mattresses with a board between them. Some people love them, but most people find the center section annoying and the whole setup overpriced. Does anyone have a mattress from OKC Mattress Company? They seem to have good reviews.
