Quantum 9000 chair AFTER 10+ YEARS

I've used this chair close to 15 years and probably about 15,000-20,000 hours of sitting.
The back tilt broke after about 5 years. It's frustrating, but not a deal breaker since it didn't affect too much. The chair still leaned back just fine.
The seat mesh started breaking, so I ordered a new seat for the chair.
