This was a great mattress for about 6 months. We flipped it and it slept good for another 6 months. After the second flip we notice low spots. It seemed you would roll into one or 2 people would roll into each other. The mattress is supported by 2 wooden boxes purchased at the same time. These required screws around the edges to stop the "quacking" sound between the wood and the plastic edge guard. Now after approx. 2 years we are waking up with slight lower back pain. This goes away after a bit but is obviously not a good thing. After reading the terms of the warranty there is without question NO need to contact either the merchant or the manufacturer for a replacement. READ THE WARRANTY..I doubt you will risk your hard earned money under these terms...

Bought this mattress before I had surgery a month ago. I had to stay in the hospital for 3 days and my back was killing me. I am a retired RN and have terrible orthopedic problems in my neck, back, feet, hands, elbows, knees and feet. I have tried the Nautilus, Sleep Number, Latex and other memory foam mattresses (probably at least 7-8). I could never have a comfortable nights sleep and it usually took me 1-3 hours to go to sleep. My husband has orthopedic problems too (replaced joints, bad back and neck). This is the first mattress we have both been able to sleep on together. I wish I had found this 15 years ago. It relieves the pressure and discomfort I usually felt in my shoulders and hips when I would ly on my side. This mattress only has a 10 year warranty (but the store owner and their two adult children have them and said it would last longer). Even if I only got 5 years out of it, I wouldn't object. Not only that I was able to buy it wholesale for $399 for a double size bed. Each size up was $100 more. That is still a cheap mattress. I was told the mattress sells some places for $1200 and yes I did find it selling for that at one source on line. I did find a number of sites that sold the full size for $489 with free shipping. It is worth every penny. In fact, I am going to tell my orthopedic doctors about it. I know they have many patients with orthopedic pain. Happy dreams!
