I purchased a Diamond mattress (Spinal Comfort) and paid more than I would have because of the 'Forever Warranty' feature sold me. I recently filed a claim because the upper portion (pillow top) is sagging. Diamond Mattress sent Integrated Bedding Group and reported 3/4" depressions on both sides, left and right, and the top left has shifted outward 2" in a 64" long area. The report also includes a faint yellow 30" stain. This was a pee stain from my baby. John, Diamond Mattress Warranty, said the stain voids my warranty. I explained it is a faint stain on the right side and the pillow top of the mattress is sagging on the left with a length of 64". This does not make sense. There is definitely a defect in materials and/or workmanship. FOREVER WARRANTY IS NOT TRUE. DO NOT FALL FOR THIS FEATURE.

Follow-up: "After a second review from the Warranty Department, Diamond Mattress accepted my claim as valid and replaced my mattress. I am very satisfied with the customer service I've received from Diamond Mattress." - Connie
This mattress wore out almost immediately! Diamond customer service is a joke! Called customer service. They said we need to sleep in middle of bed to even out gully in mattress. They blame defeats on customers! The minute you start to sleep on mattress it breaks down. Have a few friends who had same experience with Diamond mattresses! Don't buy Diamond!

This bed started to fall apart after 3 months. As the last review stated it sags. It feels as though you are sleeping in a gully of 10 inches deep by the middle of the night and you have to literally fight to get yourself out of the deep depression in the morning. Absolutely no support for your back whatsoever. We are not heavy people either. After 9 months of this bed we purchased a new mattress by Sterns and Foster and is wonderful. I didn't notify the manufacturer because personally I don't believe warranty issues are ever addressed to the consumer's satisfaction. Best scenario is that they would replace it with the same mattress so what's the use. Will never buy a Diamond mattress again.

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.

We bought our first Diamond bed when we were married in 1982. We bought Diamond beds for our daughters and recently bought one for our temporary quarters as I worked on my doctorate. Great haven, great sleep and superb durability. Just a quality bed at a reasonable price with a very good range of options from softer to firmer.
