Rated 5 out of 5 by from Comfort!! We've had our bed for just over a month, and it's been great to have it. Our old mattress was too firm and we were experiencing pain every morning. The Sleep Number bed has given us the support we need without being too firm. We love it.

Rated 5 out of 5 by from Great night sleep We previously had an air bed but this one is much nicer and we love it. Getting older with more aches and pains, this bed helps so much and is very comfortable. Well worth the money.

Rated 5 out of 5 by from CLOUD It's like sleeping on a cloud. There are NO pressure points. I find myself waking up in the same position as I fell asleep. It's wonderful. I am a Registered Nurse and took advantage of the promotion Sleep Number offered to licensed medical professionals. I can't thank you enough.
