Large Medium-Firm Wellness Seat Cushion - 17 x 13 x 3 inches

Great cushion...this is my second one...good support and holds up well.

It is very comfortable and has very good quality. I like the fact you can wash the cover.

I was so pleased when I received this product because I was afraid that it would not be firm enough to provide the needed support. It is not too soft! It has a thin layer of soft foam for comfort, but the main body of this is a very firm foam that holds its shape. I took it to work and when I put it in my chair and sat down, I had an instant improvement in my posture and comfort. I have noticed that after a few hours my comfort diminishes, so I think it is partly do to the change in position being different, or perhaps that after a few hours my rear does begin to sink in a bit. The first hour is heavenly though. I may have to buy a second one and just swap them after an hour or something.

I drive a Smart For Two Pure and have been searching for a seat cushion/wedge to raise the driver's seat because this model doesn't have a height adjustment setting. i am 5' 7" and need a little extra lift...(btw: I love everything else about this car!) After trying numerous 'boosters' without successful results; either to small/large, to hard/soft, don't stay in place, poor/flimsy construction, etc., this is the one that fits/works for my seat perfectly. It is firm - with lots of 'give' and does not flatten-out, maintains shape, firmness and height, stays in place - due to the non-slip coating on the underside. The cut-out tail bone ('coccyx') section; a feature found on more expensive orthopedic products, is a great feature; helping support my lower 59 year old (drummers) back on longer trips. This seat booster has transformed my driving experience, giving me a consistent 3-3 1/2" boost, so I now see/experience everything without straining. Regardless of price, this is the best and most comfortable option i have discovered for adjusting seat height. I can't think of anything to improve on with regards to design or quality; am very satisfied and highly recommend this car seat booster cushion!

I have a slight lumbar disk bulge, persistent hip pain, very tight hip flexors, and tailbone pain that occurs if I sit on regular chairs for too long. I bought this cushion specifically for its tilt (to open up my hip angle and take pressure off of my back and hip flexors) and tailbone cutout.So far, so good! I've definitely been able to sit for longer periods of time with more comfort, and I strongly prefer using this cushion over sitting on regular chairs/seat cushions now. I have not experienced tailbone pain since I bought this. I use it at the dining table, when I'm reading, and on road trips in the car. I'm 130 lbs and so far the cushion has not lost any of its support, but I do wish it was firmer. I suspect that it will begin to deflate over time, and will update this review if that happens in the next year.Overall, a very solid purchase that I would recommend for people seeking relief from tailbone pain and/or light lower back discomfort, as well as people looking to be nicer to their hip flexors. Worth noting, however, is that if you have more severe back pain (like I do) and you're looking to work a 9-5 desk job, this cushion alone won't cut it. It's good for shorter periods of time, but I'll be exploring kneeling chairs and other solutions for work use.

Title says all. This only covers 3/4 of the chair (and unlike some lucky people, my posterior covers the entire chair seat). The wedge makes me feel like I'm going to slide off. But "fortunately" (NOT) it goes flat/gets hard within an hour so I don't have to put up with that unbalanced feeling very long. (SMH, my regular chair seat stays comfortable longer than that!) YMMV.(I have been able to use it for a couple of hours consecutively by placing it in the center of my chair and letting my hip bones hang over the back of the cushion, but it's not an ideal configuration. I'll keep looking for a better solution.)Otherwise it is well made and doesn't slide around on the chair. It had a slight chemical odor when unwrapped but that dissipated in 24 hours.NOTEI just read that this cushion is designed to fit on a car's bucket seat (which explains the wedge and its odd size), so bear that in mind if you are shopping for an office chair cushion.

I like this item so much I've bought it SIX TIMES! Why would one backside need 6 of these? Did any wear out?? No. I don't care if this does get a "C" rating from Fakespot, I think this works great and holds its shape.BUT your DOG will LOVE IT and EAT IT because they like things you sit on often. Keep them away from this pillow seat, and you will only have to buy it once because it solidly keeps is shape and is quite comfortable.

Great product
