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.
The best chair I've owned I think with every replacement chair from Staples I keep stepping up a tier and Staples is on a whole different level with quality and value.
