After several months of sleeping on this mattress daily i give it an 8. Not as thick as my last mattress. Seems fine. The old set was really past its prime. This one seems do the job. No more aches and pains when I get up. Sleep well. I would buy again. Excellent for the price. Delivery was on time and they did text & call to arrange delivery. Note: The delivery team does NOT take away the old mattress & box spring; so I donated via CraigsList free site.
