I have no complaint about the comfort of the chair. None. But it’s very difficult for one person alone to assemble it. I needed to find someone with the strength of a carpenter to insert the casters and even he struggled. Attaching the back of the chair would have been better done by an octopus - holding all the pieces lined up while simultaneously lining up the screw with one hand and using the allen wrench with the other was way more difficult than it had to be. This needs a redesign.
My husband bought this chair for me as a Christmas present. I am working from home now and the chair I had was uncomfortable. Since using this chair I can sit longer and it has helped me from getting a stiff back and neck. I would recommend this product to anyone considering a new gaming/office chair.
