3M Under-Desk Keyboard Tray Review Design & Ergonomic Comfort
With its compact 19.4″ × 10.6″ deck, the tray fits most full-size keyboards and allows the mouse to sit on either side. The laminated surface glides keyboards easily, while the gel wrist rest alleviates pressure on wrists. Swivel range supports multiple seating angles.
