I replaced my old cushioned office chair with this one for the breathability of the fabric. Ergonomics are great and I just figured out the recline feature by pulling out on the height adjust handle. I'm 6' 220 lbs. an although the chair is wide enough, the high pointed plastic seat edge rails that hold the webbing in place can be painful if your thighs are on top of them. I thought about trimming them down and grinding softer edges to them, but opted to add a sheep skin seat cushion to raise above the design flaw. Everything else was good enough for me to keep the chair and not return to seek another.
For a 165lb 5’10 guy the seat is still uncomfortable it is way stretchier than an HM aeron and the front of your legs hit the stiff pad underneath, it’s not a good mesh material because it isn’t sturdy enough to provide support long hours. The neck rest is useless because it hits weird and only tilts I removed it.
