Here it is, from some late 90s Toyota Corolla. This seat was sitting in my basement for several years.

The easy part was cutting up the wood and measuring. The hard part was putting these damn bolts in and making sure everything was alright.

If I only had a metal grinder... hence why the chair sits slightly angled but works fine otherwise. Those little metal rods were a royal pain to work with.

How it’s put together from the bottom.... donor office chair has pneumatic height adjustment and it swivels. The chair reclines as well!

Here it is next to the first one I made 5 years ago, from a 1999 Chevy Tahoe. The Tahoe one is comfier but I like how both came out.
