Overall I was pleased with the general design to enable me to sit in a bed (senior living) and us my computer. My son assembled  it. A defective table and clamp were replaced promptly.  The specifications show the overall height as 35.5" which would leave substantial room below the table for a 6" H Canon printer BUT   , the clamp handles scrapes the printer top. Did we assemble the "L" arm incorrectly??? An additional 1.5" clearance would make this 5 Stars
