“The only mattress I’ll buy”
As long as they keep making this mattress, I’ll keep buying it. This is my second and I love it. Firm, deep and comfortable. What more could you want?

I recently switched my mattress to the Sealy Posturepedic Dupont Hybrid II , it has been the best sleep of my life. The mattress is firm while feeling like your sleeping on air it's as if the mattress forms around your body with alignment to support while you sleep. I often get hot during the night but it seems as if the mattress keeps me cool. My back posture has seemed to improve as well which is wonderful because I don't wake up sore on one side or the other. Overall I highly recommended this mattress my mom has severe back arthritis pain and I have recommended her to purchase this mattress also !!

Best night sleep I've had in years! I got this bed as a free promotion and I wasn't sure what to expect. I usually wake up several times a night and rotate my body, but since I've started sleeping on this mattress I wake up in the exact same position as when I fell asleep! I can see this mattress becoming a staple in my house in all the bedrooms. I wouldn't be surprised if my guest as where I got these mattresses from when they wake up on one after a solid nights sleep!
