I hate it! It was nice when we first got it, but now less than 5 years later, we are getting rid of it. The base is plastic. We had problems with it almost from the start....you know the "free trial" period is not long enough for the issues to appear. The sides are foam, as is the center. It collapses with time. The pillowtop does not hold up. It is truely the most uncomfortable bed that I have ever slept on. Now I called customer service many time, and while they are sympathetic, they are no help. Kinda like we give you 30 or 90 days to send it back (on your dime, by the way) so what else can we do?
This is just my experience, but $2200 for a sleep system that cannot last is problematic for me. If you want, google it along with "reviews" and read what others have experienced. I wish that I had before we made this purchase.
Whatever you choose, happy sleeps!
