Good quality and comfortable
I received this Serta mattress a week ago, and it is more on the soft/plush side. So far the mattress is extremely comfortable when sleeping on my side and back, and doesn't sink in too deeply (conforms with your body). The plushness of the mattress provides well distributed support when relaxing and trying to sleep, with just the right amount of softness. However, the mattress seems smaller than my previous Serta queen size mattress, and not so sure about the temperature regulation feature because I can't tell a difference between this mattress and my old mattress(could be due to me living in the South where temperatures are hot). I can't say enough on how comfortable it is, and the great quality of the Serta Blue Max 1000 plush mattress. I am very happy thus far with the mattress.
