Read this before you buy

We have 4 other Diamond mattresses that we have been very pleased with so it was only natural that we went looking specifically for a Diamond mattress. After the third night it began to sag. We went back to the store where we bought it and they contacted Diamond for us. An adjuster came out and found that it had a 7/8 sag. Within the range of warranty. But when I sleep on it I feel like I am sleeping in the gutter at the side of the road. I contacted them again and they offered to take it and they would inspect it at the factory. It came back one week later and it felt like they had crammed some extra padding in it. Now it was just a gutter with extra padding. I contacted them again and this time they replaced it with a new mattress. Six months later I may as well be sleeping in the Grand Canyon. Yes I am over weight 6 feet tall and 200 pounds but my wife is 5 foot 7 and 100 pounds and it was doing the same thing on her side. 3 strikes you are out. I have replaced it completely after 9 months of the worst mattress money can buy. I have read the other posts and perhaps they were lucky. I have never ever posted a negative review before but I couldn't let this go by. Do yourself a favor and buy anything but Diamond. If I could give it less than one star I would.
