Reviewed this mattress last year and really wanted to give it a few months to test it out properly. First of all it's very well made. It's very soft feeling and my husband said its the best mattress he's ever slept on. The medium firmness is a bit too hard for me but I'm getting used to it. It's holding up very well. No sink holes or piling at all. We rotate it once a month do I think that helps. It's a pillow top so flipping isn't an option which is fine, rotating seems to be enough. Once this one wears out, which at this rate will take years I'm sure, we will definitely be purchasing another beauty rest. All in all I whole heartedly give it a 10/10 and have already recommended to all my family and friends. Thank you do much for this amazing opportunity.
