Firstly, office chairs are expensive for what they are, but you get what you pay for with cheaper chairs. I was hopeful with all the positive reviews, but the chair consists of low quality materials with little structural integrity. The back of the chair/frame is not rigid and has a lot of torsional flex. Your back will contact the plastic bracing at the back which is very uncomfortable and the mesh provides no support or cushioning to negate this. The right foldaway arm started loosening at the foldaway pivot after a few test cycles. This isn’t a chair that will last, and 10 minutes after assembly, I knew it needed to be returned. Not fit for purpose as a home office chair.
