Saved this fedex driver's bottom
As a poor fedex delivery driver this thing has saved my back and my butt! All of our Ford vehicles have the seat broken and its like sitting in a bucket with the lid off. This seat cushion fits perfectly in the space and not only provides proper comfort but also the support needed to make driving comfortable for hours on end. I typically drive 8-10 hours per day and after about the 8th hour my bottom does begin to get sore while using this product. Using this product in a typical nonbroken seat probably isn't the best idea unless you have issues seeing over the dash. Ive used this product for a total of 20 hours so far. It seams to be made of quality material and the packaging is adequate. It does have slip resistant nubs on the bottom to keep it in place in your seat. Would recommend

It saved me on my road trip
It saved me on my long road trip. I don't know how it makes my back comfortable but my sciatic pain disappeared after 5-10 min of sitting. I think I was able to travel for so long thanks to this pad. And it's size and weight are comfortable for me.

Finally found a decent pillow...
Purched at least 4 different pillows. I have a 3rd gen Tacoma. Even after the seat lift, which i completely recommended. My seat was still sinking in th middle. Lots of stress on my legs. This is the perfect angle for correction. Tho, its not 100% comfortable (due to stitching) . It's a 99% correction. Im very happy! Im not heavy either. Im 5"11 210 bls. 2018 tacoma.

Simple and effective
My commute to work is 45 minutes each way and I have tried half a dozen or more different seat pads that are supposed to help prevent sciatica flare up. This one is a keeper. Most were too soft, they focused on ‘comfort’ but with lower back issues- soft is the wrong way to think about the problem. I’ve tried one other wedge design but it was too soft… if this wedge design didn’t work, I was going to just order those beaded seat covers cabbies had in their cab cars back in the eighties. I zeroed in on the wedge design because all of the other seat pad designs tried to replace the whole seat, which would raise my legs up too high. And the edges would start to cut into my thighs after about 15-20 minutes (I’m short, if you’re over 5’4” this probably isn’t something you would notice). Thankfully, with the minimalist design of this particular wedge seat pad I will remain in the 21st century aesthetic. The beveled edges of the pad fit seamlessly against the seat material and the wedge fits perfectly into that annoying gap in the supposedly comfortable bucket seat of my truck. It is soft material but stiff enough to provide support. And raises my backside up just enough to actually use the lumbar support of the seat designed and manufactured for taller people. Of course the sciatica problem is still there lurking, but this simply designed, and almost invisible addition to the seat is keeping it at bay for now. Oh, and the grip material on the bottom of the seat pad work perfectly. I don’t have to readjust it after getting in and out of the vehicle!

Really think before you buy this one. It has an odd shape and size.
Really quite small and didn’t really work for anything I needed that for. Really think before you buy this one. It is very soft and squishy, the quality is very good, but it’s so small and oddly shaped, I’m not really sure what you would use it for. It didn’t work for my back or my butt.

Relieves thigh pressure
I rarely leave reviews, but I am compelled to do so in this case. My Subaru Crosstrek for some reason has seats where your butt sits kind of low and goes higher towards the front of the seat. So your thighs get a decent amount of pressure. I’ve started developing foot pain in the last six months or so and my doctor says I have plantar fasciitis. I personally suspect since I drive a lot that my seating position isn’t the best and that my lower extremities are not getting the circulation that they need. I’ve only had this cushion for two days so I’ll see how it goes, but I do appreciate sitting higher with thighs more parallel with the ground. I do have a longer legs so that might have something to do with it too. I’ve tried a few different cushions and this one did the trick I wish it was a little less wide so it would fit perfectly but at this point I’m happy to have something that relieves the tension on my thighs.

Not Quality Material or Manufacturing.
I often order Cushions due to a health condition & was very disappointed with this one that is advertised for Sciatica and back pain relief. When I sat on the cushion it completely collapsed like the foam was made of tissue paper obviously causing me discomfort. Additionaly the cutout that is shown in the picture for the tail bone is cut out only in the foam and the cloth cover does not have the cutout so the cloth stretches straight across the cutout literally eliminating the cutout for all intents and purposes. This is not a Quality Product whosoever. Additionally the foam is of such poor quality that it came folded up in a small plastic bag. Other cushions I have purchased could never be folded so small because they are better quality.

It does what you probably expect it to
It's about what I expected. It is quite a bit of wedge over a fairly short run, which probably works very well for some seats but is a little short for mine. Nothing wrong with the product itself.

Ideal para personas delgadas
Estoy operada de escoliosis y con mil problemas. Este cojin me ayuda. Compré otro mas grande pero demasiado grande para mi que mido 1,60. Este me viene mejor pero, no es para personas corpulentas
