Comparing the N Seat Pro 600 gaming chair to the Serta Hensley office chair. Had to check out a gaming chair in person to see what they were like.

Helpful assembly instructions: The longer screws go into the multi function control bracket on the bottom of the seat. The slightly shorter ones go on the sides where the chair back and seat connect. The small, irregular washers go to the head of the screw, followed by the larger flat washer. (See pic in video)
