Older size B (two dots) Aeron with all of the features.

Some very minor wear to the seat (see pictures) and the cylinder is starting to feel like it might be losing pressure.

If/when the cylinder does stop working, new aftermarket relacement cylinders can be bought on amazon/ebay for $40-$50, and there are videos showing how to replace them.

I also have a Knoll office chair in my other ads for $60
