My seat springs snapped, I'm a small dude so I had the seat pushed up forward a little too much and the springs had a lot of angle on them. Looks like they snapped at the mounts. Got another set here, going to ease the seat back alittle so that the springs are more upright and don't take load on a weird angle.
For fun, I set the Bates seat on it. Nice and meaty, didn't look too bad but the colors clash, so the black seat will be going back on tomorrow.
