Sleep Number Mattress Questions

I disagree with those who claim that the bed will make you roll toward the middle. There must be a problem with their setup because I am quite a bit heavier than my wife and neither of us rolls toward the middle even slightly. It is a king size so that may make a difference but you can go to the store and lie down on all the different models and make your own decision on that. We had the mattress optioned with a new camper and it is the best mattress we have owned and that includes water beds.

The other answer to your question is no, we do not need electrical power once the bed is setup to our comfort and we are staying in one spot.
