The assembly became a bit of a nightmare since one of the side screws for the left arm rest came loose and had to tight it back up again. This cause the screw to not line up correctly l, hence the first picture u see showing part of the screw. Disappointed to say the least since this was such a highly priced item. Having said that, the chair is ok but unfortunately not living up to the expectations. Looks good but if comfort and support is what u seek, then I wouldn’t recommend it.
