Office chair for spares/repair

All the details

This is my old office chair. It's served me well but needs attention now, which I don't have the skills or tools to perform so wonder if it is repairable or usable for parts for anyone else. The issues I believe are: - One arm no longer attaches due to the fixing coming out of the seat (easily repairable if arms are required again. I simply used without arms) - The material of the seat is marked and colour faded due to use - The fixing for the back rest at the base of the seat has bent over time (see closeup image). This hasn't been a major issue for me, as I prefer the back close to the base - I managed to strip the thread on the knob that tightens the back rest to the seat recently. I've replaced it with a double-nut and bolt solution, though this means a spanner is needed to tighten the back which does loosen naturally with use The seat still goes up and down fine, and casters move freely. Happy to see this go for parts.
