Easy assembly. I retrofitted it to meet my needs. Put 3/4” pine on the desktop and used the slides and cut down the music keyboard tray for a keyboard and mouse tray that fit under the new desktop. Also moved the top rack from its middle position to the front and. Added an additional support for the monitor shelf.It’s MDF board with a veneer but given the price of lumber today and the time to paint and finish as well as the rack rails. Really canst beat this deal. Oh and they give you rack screws as well that was nice to see. Not all manufacturers would do that.All in all id buy it again.
