The chair arrived quickly and assembly was not terribly difficult (after attaching the arms to the base, that was definitely a challenge). While all the pieces appear to be there, there were no instructions provided. It's not the most comfortable chair either. I bought it on a flash sale and I am regretting the purchase. The seat is fine but the back is this oddly dramatic lumbar support, but no support anywhere else. I work from home for 8-12 hour days and it's a terrible fit for that.   

Pros: Great deal when on sale. 
Cons: Uncomfortable, no instructions, cost when not on sale.
