Our next bed (hopefully soon) will definitely be a sleep number. I bought my mother one which is in our guest room, but it's only a double, so hubby and I can't use it. When I bought it, my mother was aghast that I would spend so much on her at 80 years old. She slept on it one night and called to let me know that for the first time in years, she woke up without pain. She was thrilled and so was I. It was worth every penny for the 3 years of restful and painless sleep she was able to get out of it. Good luck with your decision!
