Very comfortable chair for all day usage. The mesh seating and backing is perfect for these hot summer days as you don't sweat or stick to the chair. Just the right amount of adjustability. Optional headrest is a game changer especially for long durations in a seated position.
This chair is nearly perfect and I would only suggest minor changes such as the headrest being able to raise/lower instead of being stationary at one height and being able to bring the arm rests in tighter to the chair (width of the arm rests) and being able to lower the lumbar support just a smidge further or even retract it a bit.
I was hesitant reading the reviews saying it's not good for tall people but it's perfect for me and I'm 6-6"1. The headrest can be extended a bit so might suit even taller people. The mesh material is airy and flexible great choice so far.
