HELPS PAINFUL BACK
My spine from neck to tailbone is in bad condition. I bought 2 to use in my recliner. Needed to have more firm support plus sit a little more forward so my feet touch the floor. I lean one on the lower part of the recliner back with wide part of wedge at bottom. Love tailbone cutout! The 2nd one I use strap to wrap around top of recliner. Wide part of cushion is up with tailbone cutout up. Narrow part of cushion meets other cushion in middle. Tailbone cutout is perfect to rest my head. Makes firm comfortable support in recliner for back and neck. Allows air circulation so is more comfortable than the leather recliner or pillows. Foam always keeps it’s shape and firmness. Best pain relief I have found for sitting!

Works great in multiple applications!
Two weeks ago I did a road trip (about 600 miles). It was wonderful! Your cushion completely removed the issue of recently acquired chronic sacroiliac pain (SI Joint Pain). I had borrowed a car with a 6 way power driver seat for a previous 700 mile road trip and discovered that tilting the seat forward helped. My car does not have that feature, but the cushion does the trick; even better than the power seat. Your cushion is much simpler and costs a lot lot less than replacing the driver's seat with a 6-way. At the group home where I work every other weekend the dining room table is the best place to set up my laptop. But the chairs are not suitable for sitting very long, especially with my back trouble and the height of the table relative to the chair seat is not good for typing or mousing. I found that taking the cushion out of the car and using it at the table greatly improves that situation. Also, I discovered that sitting on the bleachers at the kids' ball games using the cushion not only makes it more comfortable, it keeps the backside of my pants from getting dirty. Being not entirely waterproof the foam gets damp when sitting in the rain. So, the ease of removing the foam for drying is appreciated. The one negative that I have found is that the straps need frequent readjusting because they loosen a bit. I frequently have business to do a hundred miles away, 200 round trip. The cushion makes that trip shorter because it is more comfortable. I am embarking on a 750 mile road trip tomorrow and have a 1500 mile road trip coming up in a couple months. I am very glad to have the cushion. It is definitely the best twenty-five bucks I have ever spent.

Most expensive of one tried; BUT BEST
This is AMAZING in both Tesla and BMW seats. After Zepbound i didn’t just loose my gut i lost my ass and so mandatory for tailbone support. So happy with this one due to the angle and cushioning it was only one that felt like part of seat versus like a booster as others did. This was noted by others driving too, so YES; this is the one!

It's ok.
The size is OK, fit is fine just not firm enough if sitting for more than half hour start to feel some discomfort. Strap is a good idea to keep in place.

Great support
I like the firmness of the cushion and sturdy material. I wish it didn’t have the waffle marks that leave imprints on my thighs when I wear shorts. But still worth it
