My husband and I have a room with dormered ceiling and would like to upgrade to a King size bed. Unfortunately, there is no mode that a spring-form bed would fit around the corners that we have to take up the staircase. Does a Select Comfort bed arrive uninflated or would it be purely as difficult to move and set up as a spring form mattress?
Answers:    Comes uninflated and is VERY easy to set up. The "box spring" is plastic pieces that kinda go together resembling Legos--hence why we call ours the "Lego bed". You should have no problems! And you will LOVE it!
