Rated 5 out of 5 by from This is a basic model but that's all we needed. We've had our bed about 5 weeks and love it. My husband and I both were more comfortable the first night. My husband assumed his sleep number would be on the firm side but turns out he is at 45 and I'm at 35. The only thing I wasn't expecting is when the bed is made up with comforter and pillows it looks a little deflated. However, I am very glad we made this purchase and would do it again.

Rated 5 out of 5 by from Very comfy!! Bought this mattress on the recommendations of several people where I work that gave very positive comments. I was not disappointed. As soon as I found the setting that felt good, which took a few nights of sleeping on different settings, my sleep improved. I am still experimenting with different settings just to make sure I have the best setting for me, but the mattress is great. Now if I could only find a pillow that is just as good.

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.
