C.L.
I do not have one, but when I asked my chiropractor about one he was very opposed to it. He said they wear out quickly so they are not worth the expense. He also didn't think it would help my pain issues. He also had some negative opinions about the guarantee or warranty they provide, but I don't remember the details of it. I have a Kingsdown mattress I really like it, but it is getting older so I asked my chiropractor for a mattress recommendation.
