I am using this chair for a week now. Everything is good about this chair when it comes to comfort in seating. However, the arm rests are too hard. That means, when you are raise the chair as per your height, the elbows rest on the arm rest. Prolonged resting leads to pricking pain in the elbow area. At least there could be an option to mount some cushioning over there and this won't increase the price of the product anyway.
