The Humanscale 500 White Keyboard Tray and Humanscale 550 White Keyboard Tray are designed to support both your keyboard and mouse in a comfortable position on a single platform. By placing your keyboard in your neutral reach zone, Humanscale 500 & 550 White Keyboard Trays help to reduce shoulder strain associated with reaching forward while typing. A height- and tilt-adjustable Humanscale 6G mechanism also allows for the keyboard tray to be rapidly adjusted to properly accommodate nearly any user, and an optional palm rest also helps support your hands to minimize wrist pronation.

Check out our video review of the Humanscale Keyboard Tray Systems below.
Select from the standard 27 inch wide 500 board or the more compact 25 inch 550 board.
All Humanscale mechanisms pivot 360 degrees from the point where it is mounted to the track. Some users have a need for additional side-to-side adjustability. The lateral slider provides for eight extra inches of movement from right to left. This is a useful feature for someone at a large workstation that requires them to type facing different angles or monitors.
The track mounts to the underside of your work surface. It directs and supports the Humanscale mechanism and keyboard tray as it slides forward and back. Standard length on most mechanisms is 21 5/8 inches. That length ensures that the keyboard tray can be completely stowed under your desk when not in use. Some mechanisms come standard with a shorter or longer track. Consult each description for that information, but all systems can be ordered with any track length.
Select one of the foam or gel palm rest options for the 500 (27" wide) or 550 keyboard trays (25" wide total). For the 500 Big Board, you can select a split palm rest with one 20" section and one 7" long section, or a 20" palm rest for the 550 board. This feature comes in handy if a user doesn't want a palm rest in front of their mouse or keypad (pictured in main image above). All are covered with an easy to clean, silver synthetic leather. For users with "slim" keyboards such as those made by Apple, a 19'' "slim" gel palm rest is available. Please note that this palm rest will not reach across the entire length of the tray, and will not fit flush against the keyboard tray corners like the 20'', 25'', and 27'' palm rests. The slim 19'' palm rests will sit roughly 5/8'' away from the closest corner when installed.
The Goldtouch Go! Travel Notebook and Tablet Stand will come in handy not only when you're traveling, but anytime you want to set your laptop or tablet in an ergonomic position. Choose from seven different height settings to keep your screen at eye-level, which helps you avoid problems like eye strain and neck and back pain. This item also works well as a document holder, allowing you to input data without having to move your neck repeatedly from document to screen. The stand is lightweight and easily portable, yet strong enough to support laptops up to 17'' in length. Best of all, it's free!
A key component of any ergonomic workstation, Humanscale 500 & 550 White Keyboard Trays allow you to position your keyboard tray directly in your neutral zone, reducing stress on your shoulders and elbows. By placing the keyboard in your lap at approximately elbow height, arm extension is minimized, preventing shoulder strain. A 6G tilt-adjustable mechanism also lets you gently slope the keyboard away from you, straightening your wrists and allowing your fingers to "droop" onto the keyboard in a relaxed posture.
