When I tell you my husand I though there wasn't a good mattress out there, Until we got this Black Hybrid CX Class Mattress. This mattress is so comfortable and soft, As soon as we lay down we find ourselves falling asleep. We don't suffer with back pains or joint pain as we did with our old mattress. Also we no longer wake up throughout the night moving around contently cause our body  hurts. The bed is sturdy don't lose it's shape. I told my family and friends if you thinking about getting a new mattress this is the one to get you won't be disappointed it's  has good quality and very good values.
