Initially we were skeptical, and it took time to adjust to the mattress, but now that we have been on it for a few weeks we are in love! We sleep soundly all night, wake refreshed, and no more aches/pains. Completely worth the purchase!
It is probably the most comfortable mattress I have ever owned. It is difficult to describe how the mattress allows my body to sink into its surface and at the same time, supports my body.. Amazingly comfortable rest. You have to experience it to appreciate it.
