So far I really like this mattress, nicely priced and it delivered three days early, unpacked it at noon, (packaging was very well done) and by bedtime that same day it was fully expanded and able to be slept on. It is a very nice looking, heavy mattress, I almost didn't want to cover the mattress with my fitted sheet it's that nice looking. The memory foam is very comfortable, I would say this mattress is more on the firm side, which is great for me, I needed something different than my old soft pillow top mattress. Even after the first night of sleep, I noticed my back pain had lessened (about 30%) and it's only getting better each night (I've had it 5 nights now) I haven't really noticed the "cooling" effect, but equally there is no heat effect as well, just a comfy night sleep. As of right now, I can say, I would recommend this mattress to friends and family, and if need be, would order in the future.
