The screw holes the "nuts"embedded in the chair back were not straight. so they did not align with the bolt holes in the head rest. Eventually I drilled out the holes in the chair back and added washers to make it work. My billable rate is almost the sales price of the chair - since i am restricted to my home and needed the chair to comfortably work from home it is a wash. Chinese manufacturing tolerances are handled about the same as the laboratory controls!!!
Been sitting in it for about a week. Pretty comfy. Just wish the arm rests would be adjustable forward and back like the wheelies I do on my motorcycles.
Solid chair for the money. Able to work in a makeshift office at home sitting in it most all day. The red color is not our favorite but very comfortable.
This chair is great. Excellent lumbar and neck support super comfortable and not particularly difficult to put together—took maybe 30 minutes with two people to construct.
