Simple desk with legs, not a wall-mounted fold-down
Undo 10/10
Wall-mounted desks need studs and holes. A four-leg desk needs a tape measure. Leave a few inches behind it for cords so the desk is not crushing a cable against the baseboard.
Skip it if: The only wall is the one with the radiator or the only window egress. Do not block either.
Fits: A wall that is not a fire exit
