“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 would buy this product again and again”
For years I’ve woken up with my back and hips hurting! Until I purchased this hybrid mattress! I definitely recommend and will buy again! Very impressed!

I love my new mattress. It's firm while still being comfortable, I've been getting a great night sleep, and my back pain has been getting better ever since I started using it. I'm also a hot sleeper, and I haven't been getting as hot as I was on my old mattress.

I am a very picky and difficult sleeper. I have struggled for years with sleeping. I found this mattress to be perfect. It is got a nice pillowy top that makes the mattress comfortable yet still supportive. I have had a hip replacement so I need good support to sleep well. I will be purchasing another one of these for my child's bed as well.

We really enjoyed trying this Sealy matress. It has a very nice top layer that really adds to the softness of this bed. It's quite cushy. I would find a little difficult if I had back issues to be able to roll over in the bed with it being so soft but for people who like soft beds, it's perfect. I am looking for a lower profile boxspring because it does have a very high height to the actual mattress.
