We got this mattress to replace a Serta Sapphire mattress that guests said was too firm.  Although this mattress is thinner and doesnt carry the brand name right out of the box it was more plush.  This is a hybrid, half foam and half springs.  It arrived quickly and rolled in a box.  No issues with set up or smells. The first night was rave reviews from our friends, so thats 5 stars from us.
