I am 5' 6'' male for reference. Fantastic chair. The wheels slide over laminated floors smoothly without getting caught when they have to turn 90 degrees. The headrest is movable up and down and is satisfying when relaxing. The armrest are adjustable up and down and can be pushed out by adjusting the screws with the padding being comfortable for resting elbows. The seat is comfortable without it being too shallow or deep for the knees. The backrest has a good mix of firmness with softness so you can push your back to it when you need more support. The main dislike is the lumbar support as it is too stiff and can only be adjusted up and down but not in and out. To remove you have to break it off. I still recommend the chair just get rid of the lumbar support as the chair without it is plenty of support.
The mesh task chair was very comfortable. I was worried that the mesh would not be smooth and easy to sit on but it's great! Nice features for the price!
