That is a hack of making a standing desk with extra space for book reader holder, printer and document. It stacks 2 LACK side table to serves as storage for printer and other stuff. Then on top put a RAST Nightstand for monitor / notebook. Finally a EKBY LAVIA SHELF for holding keyboard and mouse is added by using screw.
The space between keyboard holder and LACK table can be used for storing recently used document or book.
