I purchased this mattress because I have back issues and I thought a firmer mattress would be helpful. I've been sleeping on the mattress about three weeks now and, while it's not as firm as I expected, I can actually tell the difference. My back is not as sore and stiff in the morning when I get up. However, I'm beginning to notice indentations in the mattress on both my husband's and my side of the bed. My husband weighs less than 200 lbs and I weight just over 200 lbs but both sides are beginning to show indentations already. I'm going to give it a little longer to see if it gets worse before contacting the company. Price was not bad if the mattress lives up to expectations.
