What is a keyboard tray and do I need one with a straight desk?

A keyboard tray is an articulating platform that mounts under the desk surface, lowering the keyboard to approximately 1" below elbow height for ergonomically correct typing posture. For users doing 4+ hours of keyboard work daily, an under-mount keyboard tray is strongly recommended. At OfficeFurniture2go.com, we offer articulating keyboard trays compatible with our commercial straight desk lines — call 1-800-460-0858 to add one to your order.
