Cheap MDF Board, WAY TOO much money for this cheap desk.  I am at a huge loss to explain the great reviews and those who say it takes just a few hours to put it together.  I can assemble anything including a car and this was at least 8 hours.  Screws stripped out, top CANNOT be held onto the desk with the hardware provided, had to improvise with dowels.  I don't expect it to last more than a few years.  There were dings, one very visible.  Much of the trim does not line up.  A real piece of garbage....cheap, cheap, cheap.......extremely difficult to assemble (33 pages of instructions & diagrams), many parts NOT marked and it made a mess in the room with all the foam packing material breaking apart.
