The back support is nice and the back mesh is breathable. I’m pretty petite however (5’2”) so the arm rests are way too wide for me to be truly ergonomic. Also the mesh material on the arm rests and seat are pretty rough and isn’t super comfortable on any exposed skin. Lastly, unfortunately the foam in the seat pad and arm rests feels pretty cheap, so I definitely wouldn’t recommend this chair for sitting in 8 hours a day. Would be much better for shorter sitting periods and for a taller/bigger human.
