Memory Foam Wedge Seat Cushion for Car, Office - Truck Seat Cushion for Driver, Relief of Back Pain, Sciatica, Long Sitting - Non Slip Wedge Cushions Car Pillow for Driving Seats ‎17.5 x 15 x 3.5"

I ordered this wedge cushion from Amazon.com after learning from Bob and Brad's youTube videos about the importance of appropriate standing and sitting posture for people like me who are struggling me with a herniated disc and sciatic nerve leg pain/numbness. From the moment I unboxed and sat on this wedge, I've noticed an improvement in my back and legs. What a relief! Just as advertised, it works in my car, office chair, and various-sized dining room chairs, The design is attractive, comfortable, and sturdy, and the strap is handy for carrying it.

The seat in my Kia Soul just didn't feel right. My knees were too high and my rear end was too low, causing pressure under my legs. This cushion is just right. It fits well on the seat, provides just enough support, takes the pressure off from under my thighs and allows me to see the hood of the car.I tried the Desk Jockey cushion -- it was too firm for me and too small. And I tried the Everlasting Comfort cushion -- it was too soft and my back started hurting in under 2 minutes. This was definitely the winner. And, it has a strap to keep it in place.

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.

I bought a few different pillows to address the sciatica I was getting when I sat for a long time (desk, car, attending basketball games) and this one is the best for me. I’m heavy, 250+lbs, and this thing is comfortable and doesn’t lose its shape.

If you are just looking for a cushion between you and a hard chair this will work, but the contents collapse when sat on and have zero mechanical effect as a wedge. A better choice would be more dense or harder wedge that will lift the hips above the knee level. The non-slip grip was effective, but the other issue was the cushion is so wide that I couldn't fit it on our dining room chair (that has a curved back).

nice and comfortable

It helps bring your back up level in a bucket type seat. There is just enough elevation in the back of the seat and it gradually decreases to give the most comfort to your legs. I have is buckled around the seat and it does not move. I highly recommend it!

It also came with a strap that, you cannot remove. So this is JUST for in the car and done. No using it elsewhere or moving it.Not so thick one and one with no straps is what seems best for the consumer. This is not it.
