Rated 5 out of 5 by from Best sleep ever! When I bought my sleep number in August 2016 I was skeptical. I had issues with my lower back and my legs. After two months I have noticed less pain in my body and can operate better

Rated 5 out of 5 by from back pain I have been battling back pain for 8 months. All the pain was gone in the first night. Honestly I couldn't believe a bed could make that much of a difference. We were in a 5 yearold $1500. Mattress prior so that there is no mistake about the prior quality. My wife wasn't comfortable untill she added additional mattress pad as that is the only diff in price from model to model. I would have no problem referring this product. My Sleep# is 65.

Rated 5 out of 5 by from I would never sleep in any other kind of bed! I bought my bed 19 years ago and have never had anything like it! I had to replace the pump after 18 years, I surely wont complain about that. I am getting another one for my guest room while they are on sale. Love My Sleep Number!!!

Rated 5 out of 5 by from We purchased a second After eight years of sleep comfort for our selves, we purchased a second for our guest bedroom. We would not have done so if we were not completely satisfied with our own. New remote control is great.
