Office Star Mesh Back & Seat, 2-to-1 Synchro & Lumbar Support Managers Chair, Black

Yeah I figured that out about the leather!
Mesh-back seems pretty good, which is actually what I have on my current chair, but the place where you site is only half mesh and the other half is dying :/
Not sure if full-mesh chair are durable?
I was looking at Ikea MARKUS and some of that kind too
I don't have one but know someone who has one of these: https://www.amazon.com/Office-Star-Synchro-Support-Managers/dp/B01EHQ5GNS/ and compares it to the Aeron chair.
