A Bit Pricey But I Love It
I did a lot of research before deciding on a Seat Cushion for use in my car (for a long trip) and hopefully to improve on a cheap, uncomfortable office chair.<br /><br />In both cases this Cushion has worked great.  It's a bit heavy, but that helps it stay in place (plus the bottom has a very effective rubber surface) - once down it doesn't budge.  Sitting on it is like floating in air - almost no sense of contact.  It made a HUGE difference on my car trip, driving 15 hours at a time, stopping only for gas.<br /><br />For daily use in the office, it has transformed by cheap, uncomfortable office chair into an ultra-comfy work environment. Not too cushy - it kind of feels like you are floating just above the seat, but still holds you in place. No sliding off the edge and it stays in put even if you get up and down 500 times a day.<br /><br />I weigh 145 lbs, but I've had family members up to 175 lbs use it with the same results.  Can't say for sure what would happen much above that weight because I haven't tested it there, but for me this thing has been absolutely great.
