the chair is nice but not really sturdy the arm was wobbly and there is no way to tighten it but as soon as I told wayfair they immediately made it right they shipped out a replacement that day (great customer service) as far as the chair goes I like it the automatic up and down it is much  easier on legs and knees I don't think it will hold up for the long term frame is kinda thin but it is comfortable and made for a bigger person i was worried about the foot rest but it is actually comfortable for the price I think it is a good buy
