There is nothing wrong with this high quality, well made mattress except that it is mislabeled.  The description states this is a plush mattress. There is also a firm to plush rating diagram near the last page of the product pictures which shows that this mattress to be more plush than firm. However, I believe this to be a mislabeled description as this is the firmest mattress I have ever slept on. This is not like the memory foam mattress I am replacing where you sink into the foam some and the foam bounces back when you get up. This mattress doesn't allow you to "sink" in the slightest bit. My body lays fully on top of the non-compressing foam. I am a side sleeper and find that this makes my hips and shoulders sore in the morning. My husband finds this mattress comfortable as he prefers a firm mattress and sleeps on his stomach. I just hoped that this would be our happy medium, but sadly, it is not.
