Review on Air Seat Innovations Seat Cushion: Enhanced Comfort for Office Chair, Wheelchair, Car or Truck Driver Seat - Alleviates Lower Back, Coccyx, and Sciatica Pain - 18” x 16” by Todd Worley

I was looking for a pillow that would not shrink over time and would protect my spine and tailbone. I especially needed this cushion for our lawn mower which gets very bumpy in an acre of what some call a lawn, we call it a "field" manicured to look like grass. When you're done mowing, any bumps will affect our backs. As we were older we figured an airbag would help. Well it helped! I still felt my neck after the haircut, but my tailbone and spine felt fine. As the saying goes, getting old is for birds. I found the price a bit high but the product is very well made and looks durable enough to last a while. The ability to inflate at will also helps. Depending on your weight, the amount of air used will likely vary. So far so good with this pillow. A bit pricey, but so far it's been worth it. After all, we want to keep our bodies, don't we?!
