Abstract: A folding keyboard height extender with a top plate, a bottom plate, and a right and left side hinged side arrangements. Each hinged side arrangements has an upper plate and a lower plate that are hinged to each other and between the left and right side edges of the top and bottom plates. A folding shear lock plate is hingeably attached to an underside of the top plate. In a first extended state, the right and left side hinged side arrangements form tall and straight walls, and the shear lock plate is swung down perpendicular to the top bottom plates and to the right and side hinged side arrangements. In a second lowered state, the upper and lower plates of the right and left side hinged side arrangements fold out away from the top and bottom plates lay flat against each other, and the shear lock plate is folded up and is sandwiched between the top plate and bottom plate.

Each hinged side arrangements has an upper plate and a lower plate that are hinged to each other and between the left and right side edges of the top and bottom plates. An inner folding wall is hingeably attached to an underside of the top plate. In a first extended state, the right and left side hinged side arrangements form tall and straight walls, and the inner folding wall is swung down perpendicular to the top bottom plates and to the right and side hinged side arrangements. In a second lowered state, the upper and lower plates of the right and left side hinged side arrangements lay flat against each other, and the inner folding wall is folded up and is sandwiched between the top plate and bottom plate.
