We got the Sleep Number bed when our waterbed finally sprungĀ a leak after 16 years of service. I was skeptical at first about whether an air mattress could provide adequate support, but I have been pleasantly surprised! I sleep soundly, don't need to toss and turn to find just the right position, and can adjust the level of firmness quickly and easily with the touch of a button. There are two things I would do to make Select Comfort's product even better: 1. Periodic monitoring of air pressure to ensure the mattress retains its desired inflation point; and 2. offer a heated mattress pad. Coming from a constantly-heated waterbed to an air matress, that thing is downright chilly!
