I have a sleep number bed and I love it. I have had back problems and neck problems for years. I don’t have any now. You can adjust these beds to any comfort level you want. I don’t like to soft of a matress; so I use a higher setting. Have had no problems with in in the 6 years I have owned one.
I am glad you like your sleep number beds.
As I said, earlier, while I wasn’t comfortable on them, but different people like different things, and eveyone needs to find what works for them personally.
