While I do work an 8 hour day and this chair is only recommended for 3-5 hours at a stretch I get up often enough in my duties that it never even gets to that point I love the mesh back the spaces this chair can fit in my office. With the seat and arm rests at maximum height for my own personal comfort I can still push my chair under my desk and out of the way without the arm rests getting damaged squished or otherwise messed up. Great buy!
This is the first mesh chair I've bought. It is holding up quite well. My biggest concern with mesh was durability since I can just see poking a hole through the mesh with a pen or pencil. It is comfortable to sit in for long periods. My only issue is the breathable seat cushion. It is rough on your skin if you are wearing shorts. I think I would prefer that Luxura faux leather instead with my next mesh chair. Plus I did see one like that in the catalog.
