There appears to be a bit of a wobble left to right when tilted back slightly but not when the chair is straight up. Otherwise it is comfortable and the upholstery appears better than average.
Chair is good looking easy to assemble holds height position well. Seat is comfortable and movable armrests are a good feature. Reason for a 4 is that my shoulders hit the pillow part of the chair when I sit back which is uncomfortable after a few hours. I’m 5’11” probably designed for 5’8” or 5’9”.
The chair feels good looks good..... A bit difficult putting it together. When completed the chair had a tilt to the side and I just could not figure out how to correct same. All the plug in fillers did not stay in place. Over all it is a chair I can live with in my office
