Reading time: a few
Your wheelchair seat is made for long term seating, hopefully.
Other seats are not. That’s the issue.
What to do?
Specifically, what to do in a car?
I’ve done extensive research and found a good seat at a good price. It makes any drive a lot more bearable.
This is the answer.
SUNFICON Inflatable Air Seat Cushions
I don’t recommend the color black, it’ll be hot in your car in the summer. Mine is grey.
Immediate actionable items: Buy this, or something similar for a seat in your car.
Summary: A cushion for your car.
Overdeliver: This can double as a cushion for dire times, or on other seats that aren’t cushioned.
