The seat is comfortable and the placement of the armrests is fine. However the lumbar support dug into my back and only had a small amount of vertical adjustment. Also the bottom of the headrest dug into my shoulders even in the highest position. (I am about 5' 11" 210lbs) If the headrest and lumbar could be more adjustable this could be a great chair. The overall build quality is better than most similar chairs i've seen.
I work from home and sometimes 8-10 hrs a day. Comfort is a requirement! This chair is one of the best I’ve ever worked in! Lots of features and great value!
