I knew this would be the best mattress in the store, but was I willing to fork over what it cost? Took me 4 years to be completely fed up with current mattress and take the jump. I should have done it sooner- first night on the mattress was unexpected comfort. Rested in the morning, very few turn overs in the night. No back pain and no stiffness. I have the firm, but it is more like a medium and it's perfect. It does have a chemical smell that I expect to go away soon- I don't care- it's a great mattress.
