I have only had this mattress for about two weeks but I have been sleeping on it very well. I am a 24 years old weighing 180 and 6 feet 2 inches tall. The mattress has a softness like marshmallow and does keep me cool at night as I have noticed way less overheating compared to my previous mattress. I paired it with the casper hyprid snow pillow and been getting a good amount of body alignment, cooling, and sleep overall. A little expensive but it is a good investment.
