I purchased this mattress because of my husband's back, he seems to like it, but it doesn't seem to be holding up as well as I had hoped. I don't like it at all. It made my bed lower and it's too hard (I ordered the firm)!! When ordering this bed for someone with back issues, remember that you have to sleep on it too! I use to love sleeping in on Saturdays, but now I can't wait to get out of bed!! Very uncomfortable!!! Unfortunately, I can't return it, because I already slept on it!!!
