This mattress is extremely firm and unfortunately, keeps me from a comfortable night of sleep. We purchased it because it was ranked high for it's 'cooling' feature, which has been fine in that area, just way too firm for my liking. Unfortunately, we are past the 'trial period' and cannot return it for something better suited for us. I am giving 2 stars, only because the delivery time was great and we are pleased with the adjustable frame.
