We are in the market for a new bed. Wife wants a sleep number bed. I dont really care. The sleep number bed has dual remotes, massage feature and can bend like a hospital bed. All for about $5000. To me it looks like a cheap air mattress with foam around it. Is there anything to these sleep number beds? Do they work? Do you sleep better? Do they last? They certainly seem expensive, but then again a top of the line Sealy is about $2500 or more. Anyone have one of these and can tell me how they are?
