I was skeptical about this mattress due to the price, but from the first night I slept on it, my back pain has gone away and so far it hasn't returned. I can only attribute this development to the new mattress. I've also noticed that I sleep better in general. This is a very comfy mattress and if there's one thing that's perhaps a con, it's that when I get too close to the side, I almost slip off. Otherwise, it's excellent quality for the price and I hope it stays this way for some years.
