I sat in many chairs and of all of them--even those most expensive--this was the most comfortable particularly if you are at a desk or a computer for long periods of time.
The one in the store seemed very supportive but once it was put together in the office it didn't have enough seat or lumbar support for me although I am a bit overweight.
Chair is reasonably comfortable in the seat arms are very limited in motion. The hydraulic unit on my chair does not stay at its setting so while I raise the chair it lowers incrementally while sitting. Infuriating. Replacement part is back-ordered two months.
Comfortable chair all around. The only thing I would change is the ability to adjust the level of the headrest up and down. I’m about 5’11 and I can feel the bottom of the headrest touch my shoulders which is kind of annoying. This chair is probably better for shorter people.
