We have the sleep number an I love it. We can adjust it to what we want too.. I am a 75 ... my husband is 85. We have had it for 2 years now an It has really helped me sleeping. I have a really bad back.. Lots of surgeries an its the only bed that I have really slept good on. We have a king an I dont feel my husband turning over or anything. It the best investment that I ever have done.
