A while back my seat collapsed in my car, and I've been getting by with jamming pillows in the collapsed space covered by a towel so it doesn't cut me.
Now I'm going to try salvaging the passenger seat to see if I can use that instead. I've never worked on a car before. Wish me luck!
Sad news. The two seats are different enough that swapping the broken part is beyond my mechanical aptitude. I'd have to buy a whole seat or hire a professional to try the swap.
