I have a 2023 Chevy Bolt, supposedly with the "improved" seats. Unfortunately Chevy let us down as the seats are still poor. The driver side, while powered and adjustable, lacks lumbar height adjustment. The passenger side is manual, with even fewer adjustments. Neither is comfortable after 30 minutes. I put this on the passenger side and my wife reports that the seat is now acceptable. Our only issue is you can't tuck in the straps on a car with ventilated seats apparently. The venting comes straight up the back so no crack to poke the straps through to the rear. That said, it seems to stay in place pretty well.

This review is by a 6'2" male who drives a 2019 Subaru Forester. I would get lower back pain after about an hour driving my SUV. The SUV's lumber support did not help. Adjusting the seat was inadequate. I was drawn to this product because it was not too thick but was a little worried about it after reading some of the negative reviews and was concerned because it was not adjustable. I decided that I would be able to figure out some way to lengthen or shorted the straps if necessary so I purchased it because the price was so low. Just got back from a 1300 mile trip where I was driving over 4 hours straight. It exceeded my expectations. For whatever reason it fit me perfectly without any adjustment. I could feel the perfect level of support the first time I sat down. It stayed in place without too much trouble. I don't like to give such lofty or lengthy reviews but pretty much had no choice here. I considered a Comfort demerit solely because it appeared to get hot but decided against it because my back probably would have gotten hot either way. If you're looking for a slimmer lumbar support go ahead and take a flyer on this one.

So many of these cushions are too thick for a desk chair and you end up sitting on the edge of the seat. This one is perfect "¦. Thin enough to fit well yet provide adequate support. The straps provided to secure to an auto seat are long enough to fit around the back of my desk chair and by criss-crossing in back, holds the cushion in place correctly. This choice was a win!

I installed this under seat covers, so it stays in place very well It installs easily, but without a seat cover it might shift around a bit. I would have preferred it to be slightly thicker but not as thick as most that are available. (I realize that everyone has different needs and preferences.). So overall we are quite happy with it.
