Bests & Worsts Reviews from Amazon

1 Year Review: It's now been about a year since I started using this mattress. I'm happy to report that it's still as great as it was when I first started using it. No permanent indents, "valleys", or any other issues. It's still looks and feels as good as it did when I first bought it. No issues with it being too hot or not breathing enough either (this is in Texas). Great, highly recommended. 3 Year Update: It's now been over 3 years since we bought it. It now definitely has some minor valleys where we sleep on it. But it's still comfortable enough that we'll keep on using it and have no plans to replace it anytime soon. 7 Year Update: We got a new mattress. After about year 5 it had some serious valleys and wasn't very comfortable any more. The last couple years we were sleeping on top of a comforter on it, which made it comfortable enough to keep for a while longer.
