WonderGel for computer chair and sciatica
This WonderGel Extreme works very well but while it cushions great, the abrupt edge,isn't ideal for my sciatica in a car.  It works very well in a chair where I can put my feet up a bit on a stool below the computer desk, then the 90 degree angle edge doesn't create a problem for my leg/sciatica.  It its defense, everybody and every BODY is different  It might be great for you in a chair and in a car as well.  I bought this one first based on reviews and am happy with it, for use in a chair at the computer, feet up a bit on a stool.<br />I also bought the Conformax Airmax Gel Car/Truck Seat Cushion by Crinnis Corp (here on Amazon) which I use in the car on road trips, they are 15 hrs long.  As my issue is sciatica, I use the Conformax in the car, then take it out from under me for a time, changing pressure, replacing it a few hours later.  Alternating with/without works better than all of the time using the Conformax and definitely much better than without the Conformax<br />Read the issues about the Conformax and this WonderGel Extreme Seat Cushion and high temperatures in cars.  When not in use I keep in covered, in the car, in back under a cover with insulating blanket over it.  Sitting on it in high (summertime/in sun, closed car) may mess it up and the limited warranty. I use this AND the Conformax, very happy.  The cost of both is far less than neurologist visits!  Prevention is the best medicine (this from a retired healthcare worker!)<br />In short, well worth the money, both of them together, one for the car, one for the computer chair.
