High Quality and comfort, low price

I'd rate this as a 10 of 10 product. I feel that it is just as described with it being very soft to the feel with enough support to keep you from sinking too far. A perfect blend of comfortable and supportive. I've had 13in mattresses with cool gel costing over $2000 and this mattress is right on par. I'd sleep on this any day of the week. Ordering my 4th mattress today and would highly recommended. I'd also like to note that they usually inflate close to 11in rather than 12in. Regardless it's a high-quality mattresses with a simple design. I believe most people will love it.

Better than Beautyrest

I was sleeping on a Beautyrest for the last 7 years, but the inner springs slanted and I felt like i was falling off the bed. With this bed, I am sleeping so much better. It is soft enough and just firm enough to help me sleep well. I don't have to worry about it slanting over and it cradles my body nicely. This is a great bed for heavier people.

Delivery was quick, setup was a breeze. Oh my, compared to the old mattress, we are sleeping and resting so much better. We purchased two twin xl and replaced a queen size mattress. It is wonderful!
