First impressions:  Ahhhhhhh....ooohhhh....relief!
I just received this day before yesterday so this is an initial impressions review. I'll follow up in a few weeks.<br /><br />First, I bought this for my office chair, which is an excellent chair with lots of adjustment knobs and levers that I bought (lightly used) for home use 12 years ago. I've now been working from home for almost 5 years, and the seat recently just seemed to turn to concrete. For weeks I've been unwilling to get on an exercise bike after sitting all day because my tush hurt so much, and it finally got to the point that two hours in this chair had me squirming in pain, my whole lower back hurting. Replacing the whole chair seemed ridiculous: everything is in great shape except the seat cushion, and getting a chair with a similar set of adjustments would be well over $300 (this chair retailed for $330 in the late '90s.) So, for weeks I used various cushions from around the house (including memory foam), a borrowed wheel chair cushion with gel, 3 layers of an excellent closed-cell foam exercise mat: nothing helped.<br /><br />I used this WonderGel Extreme Orthopedic Seat Cushion yesterday for the first time, and sat 6 straight hours with no problems at all. I worked a couple of more hours in the evening, no problems. This truly feels heaven-sent. I highly recommend it for any use - office chair, wheel chair, full-time driving, etc. It has a good cover on it; one side has a no-slip texture to prevent the cushion from slip-sliding when in use, and a sturdy carrying handle. This version is not light: it seems to weigh about 5 or 6 lbs, or as I told one friend, "think laptop not netbook" if you're thinking of lugging it around. They do seem to have lighter models, including the Orthopedic Wondergel (Intelli-gel) Roll & Go - Gel Seat Cushion, which at 1 inch would be half the depth and less than half the weight (the dimensions are slightly smaller). The original model is 1.5 inches, same dimensions as this model, and comes in at 3.9 pounds, so my guess on the weight of this one is about right. (http://www.amazon.com/Wondergel-Original-Gel-Seat-Cushion/dp/B004EMXZKW/ref=pd_bxgy_hpc_text_b) For occasional use (driving, stadium, church or theater seats, etc) I would have gone with the one of the lighter models, but for full-time use I'm guessing this is the better choice, though it might be more than is needed for a petite woman.<br /><br />Overall, remarkable set of products, highly recommended.
