Construction is reasonably easy all parts are marked and the hardware is specially packaged. The quality is... worth what you pay since this is a low-end price for a specialty desk chair. The adjustments are stiff and cheap and have only one or two spots not infinitely adjustable. THE HEADREST: just don't bother putting it on. It thrusts way too far forward and is not adjustable front-to-back you won't be able to sit up straight with your back against the chair back.
