I rec'd email which reminded me it's been 8 yrs since I've purchased this and I still use it. When I bought it I was thinking this memory mat'l will probably wear down. It has not. It is still like new and I recommend it hightly. I originally bought it to enhance a cheap, thin mattress I bought for a 2nd home but I ended up using it in my primary home where I sleep on it 80 percent of the time. It's a great product and I have gotten much more than my money's worth.
