Guest contributor Janet Peterson, PT, DPT provides a concise, useful guide to keyboard trays as a means to add adjustability to a fixed height desk or work surface. She provides actionable advice on when a keyboard tray may be the right solution, what "must-have" features to look for, and which optional features will improve workstation ergonomics. She also offers considerations for corner and "U" shaped work stations, and provides wise words of caution regarding keyboard trays advertised as "sit/stand" or "sit-to-stand".
