It does require some assembly which is fairly easy with a screwdriver.  I do suggest attaching both arms to the base BEFORE you try to attach the back, otherwise it gets tricky trying to get the inner corners to go on.  It is very comfortable and well made.  It is a steal for the price!  I know it looks similar to cheaper chairs but I assure you that the quality is well above those.  I bought two and they both came quickly with no missing parts.
