It’s got that ideal mix of soft and support.

- Sandra P., Portland OR

I loved the feel of the cooling gel the moment I laid down on it in the store. After my first night on this mattress, I woke up the next morning feeling like I’d been asleep for days, it felt that good. It doesn’t make you feel like you’re sinking in the middle or anything like I thought it would. It’s got that ideal mix of soft and support so that there’s no soreness or anything. It’s really like sleeping on air, as cliché as that may sound. I tell all my friends and family and even my co-workers that this is the mattress for them.

I loved how the cooling gel wrapped around my body.

- Deanna V., Canby, OR

It is hard to choose one mattress out of all the ones they have on display at the store. And of course you have to lay down on them to try them out. None of the others I laid down on compared to this one. I loved how the cooling gel wrapped around my body. And it really did stay cool. Not once did I kick off the covers or toss and turn. I stayed in place and felt well rested, which is important in my line of work. In short, I’m really glad I tried this mattress out and bought it. If you are looking for a mattress that will keep you cool all the night through while providing back support, this one’s definitely it.
