Interesting material but never really was that comfortable for long term sitting...
Its works as it says. There isn't much pressure but its not really all that comfortable to sit on. I used it for many months trying to adjust it because it was so expensive I didnt want to waste it. I tried it under my butt, behind my lower back,  on my upper back and shoulders. Nothing really worked... I could see the material being great for a bed but not for a small seat cushion. Now it just sits in my closet never to be used again only to remind me how much money I spent on it. I wish i could find a use for it... I let others borrow it and they didnt find comfort in it either....  I would love to try the mattresses they make but I really cant drop that much money for another failure.
