      First of all, the description of this mattress should not have Coils in it. There are NO coils or springs in it. They used the words Support, Durability, Traditional Innerspring Design, High Performance Coil System, Innerspring Coil Density, Edge Support System, Tight Top. This is most deceptive. This is a big sponge and the first night you sink into a hole and stay there. The third night I woke up like a knife into my back and I slept on the edge which sunk about 5 inches down but at least it was open on one side. This sponge is Soft, Soft. There is nothing firm about it. There are no springs, there is no side support. It crushes to about half on the sides. Maybe a small child could sleep on this sponge. I have been a steady shopper at but this purchase really shakes my confidence. Know what you are buying with this one.

      Great mattress! It reduced my back soreness throughout the night by at least 90%. It works well on my adjustable bed, since it is one sided only. My only peeve is that it took forever to be delivered. About 5-6 weeks. Well worth the wait. It is a level 3 firm rating. Overstock did give me a partial refund for waiting so long. I would get another one in a heartbeat. Thank you Overstock!!
