I waited a full week of sleeping on my Sealy Copper Chill to post a review.
This bed is so amazing! I have a bad back and hip issues, which most beds make worse. The Sealy makes them better. I think its even helped them. 
The bed is firm, but not too much. If you prefer a firm mattress, this is the one you want! This mattress stays nice and cool all night.
I highly recommend this bed, you wont regret it!
