When we reviewed this mattress before purchase, people said the mattress was essentially a good middle of the road mattress. We find that it does not give adequate support. The first couple of days of using the mattress, we both had back soreness, so the mattress takes some adjusting. Sitting on the side of the bed, we found that the mattress gave too much, and did not support our weight. Sitting on the corner of the mattress was even worse. Additionally, when one person gets into bed, the other definately notices. The mattress, although we consider it an "ok" one, is too flimsy. It is fine for what we need it to do, but we would have been much more satisfied getting another model.
