A time ago i bought a electrical adjustable seat for cheap.
It also had orthopedic backrest.
Both these option are very rare here, i have never seen electric seats, and orthopedic twice.
But the color was wrong, i have a green cloth interior, and the seat was beige.
So the idea was to swap the cloth.
I also had heating element laying around, so because im already there, im putting those also in.
Then i encounter a problem, the backrest seat was not good.
The cloth was not tight in the corners, you could feel the airbags of the orthopedic. After examing the old cloth there is extra stuffing inside it.
I cut it out with a stanley and cloth it on the seat.
The result was good.
