Sims Furniture Purchased a bedroom set with a Consolidated Bedding Mattress. It is five months to the day and it has a 1" sink hole on both sides of the mattress. I was told that this is acceptable by manufacturer standards. I disagree, both my husband and I are under 125 lbs. We have two sink holes in the mattress with a large hump in the middle. The technician that came to report said it was bad; although Sims states it is fine. It is not fine. They will not do anything to replace this. Both my husband and I wake up each morning with backaches and actually have a bit of difficulty getting out of the hole!
