Review: Outstanding quality - very supportive and comfortable
Review: 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!

## Questions & Answers

**Q: Will it fit a car’s bucket seat?  Is it really higher in the back than the front?**
A: Hi, thank you for the question. The wedge seat cushion is suitable for most car bucket seats as it measures approx 3.25" at the back and tapers off to 0.5" at the front. The cushion measures 17.5" along the front (side to side) and 15" from front to back. Hope this helps. Lucy.

**Q: In what country is this manufactured?**
A: I have searched all of the pillow itself and there is no indication as to country of origin. After some research, I believe it is made in the UK.
It us well made  and does the job for me.  I am 4'10" and it adds just enough to made visibiity comfortable for me.

**Q: Does this better the posture?**
A: In my situation, Sacroiliac pain, using this cushion helps by changing my posture to lessen the pressure on the joint. I use it mostly for driving and sometimes on the dining room chairs when I use the table like a desk. I also use it when sitting on the bleachers in the park. Check out my product review.

**Q: What wedge pillow would give me the most height as I am short?**
A: The Ergonomic Innovations wedge pillow gives you about 3.25" in height at the back of the pillow which is higher than most sold here on Amazon. Hope this helps.

### ⭐⭐⭐⭐ Works great in multiple applications!
*by G***S on June 12, 2018*

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.
