I just picked up this aeron for free, found it on facebook market place in the area just listed as office chair with only one picture luckily i knew it was an aeron went to pick it up immediately. Everything seems to be in perfect working condition. Only have a few questions.

The arm rest feel a bit rough to the touch anything i could do to improve that?

The lumbar support plastic in the back is cracked, could i just glue it? (See picture)

It also a size c but im only 170cm 60kg (5'7, 130 pounds) is it really that big of a deal? It appears to fit fine at first glance
