We love it!
We're really happy with our mattress, which we've been using for about 6 weeks now. It's very comfortable, and we've been sleeping so much better. There is very little movement on the mattress when the other person rolls over/changes position. The mattress is firmer than I expected! I would have preferred it to be slightly less firm but it's perfect for my partner who has back problems. Overall, we are very satisfied, and have recommended the mattress to others.
