Hello, I am listing my expensive gaming chair for sale to someone who hopefully knows how to fix this and breathe new life into it. I've used this chair for years and took care of it the best I could. I ended up replacing the wheels, base, and piston with newer and stronger versions of its former plastic pieces.
This chair originally was $649.99 and at the moment I believe its still for sale for $599.99. I also put another $170 into the lower parts of the chair.
The issue is the chair plate, tilt plate, I don't know what you call this piece has failed. You can see in the pictures where there's a crack in the metal. If you know how to remove this plate and replace it with another you'd have a nice wide gaming chair.
