This mattress is better than the more expensive ones we have had. It is our second one, we ordered the queen size about 6 months ago and love them both.

Mattress is a bit too firm for me and my husband.. wish the foam layers were a little thicker, just feels like a hard, springy mattress. You get what you pay for. I know there is a warranty and it can be returned, but who in the world is capable of shoving a mattress back into a box in their home? 3 stars because it was very affordable and I like the grey color. Just wish I would have gotten a memory foam mattress instead of a hybrid as it is too firm.
