The Garden Sleep System mattress is not like the Sleep Number bed. I am not even sure if is air driven. By my experience with this bed has not been good. I stayed at the NYC Chelsea 3x over last couple weeks and I never had a good night's sleep (even on a night when i took a Tylenol PM pill).
The mattress is not like an ordinary mattress as it does not breathe very well. Is almost like sleeping on hard foam and i feel like being suffocated and have to roll over several times during the night. The adjustments do work but only the center of the mattress is affected. I am a side sleeper so that may be why. I see their ads had a back sleeper.
Anyway - thats just my 2c. I hope others have better experience.
