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"

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!

I have EDS. My lower back discs around tailbone go out frequently and at times take 2 weeks or more to become functional again, where I can get out of bed and actually walk. Sitting can be extremely painful sometimes, and I am SO HAPPY to have found this 3inch wedge cushion; it lets me sit comfortably for several hours at a time, ..in my office chair, in my car drivers seat, and even sitting on the floor with this cushion. It is also awesome to bring to restaurants that have uncomfortable seats.

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.

I ordered two different cushions for my car and this one did not fit properly so I suggest anybody who is getting this for their car is to measure your car seat appropriately before you purchase this item

nice and comfortable

This cushion seems to be remarkably effective at ameliorating my sciatica while driving my car. I am tall enough that my car seat cannot go back far enough without also lowering too much. (It's a 6-way, rather than an 8-way seat.) Thus my knees would end up being somewhat elevated or my legs bent to the sides, and after 45 minutes or less behind the wheel, I'd have pains running up and down my right leg. The cushion puts me in a better position. I have yet to take a long drive, however, to see how much it helps with three or more hours driving; I'll see.

I do a lot of wheelchair positioning as a therapist, and to be truthful, someone didn’t measure the usual depth of a bucket seat, cushion is too short in depth. Nor did they consider the thicker part of the wedge if in the back (as in the picture), of the seat interferes with where the adjustable lumbar support pushes out of the back cushion. Plus sitting on the thicker part of the wedge in the back is like a slide causing the pelvis to migrate forward while driving. Since I am a therapist, I knew flipping it around so the wedge was in front so my hips were flexed more and gas peddle location actually more proportionate to my leg length was much better! But I would still like a deeper cushion for all over thigh support. I will make do as I hate returning stuff. :(As of now, I donated it to one of the nursing facilities I work at. The lady uses it in her recliner instead.
