Bought a Sleep Number in January - best ever thing I did. I control my side of the bed, and there is control for the other side. You use normal sheets, and I have a heated mattress pad that I use in the winter. I have a king, it wasn't cheap but when comparing it to buy something of similar quality at Homemakers or comparable it really wasn't that much more and there was no deliver fee. Personally, I would never buy a bed off the internet unless I went to a store first and checked it out.
