Humanscale 900 keyboard platforms are our most popular choice for users with a standard shape or split ergonomic (i.e. NOT "natural" or curved) keyboard. These sturdy keyboard trays are constructed from phenolic for a sanitary, durable typing surface, and a clip mouse platform system provides an exceptional range of mousing surface adjustment on either side of the tray for right-hand or left-hand use. The mouse platform tilts separately from the keyboard platform, so the mouse can rest on a flat surface to avoid sliding off even when the keyboard is tilted.

Check out our video review of the Humanscale Keyboard Tray Systems below.
Humanscale 6G, 5G and 2G mechanisms are a vital part of any keyboard tray system. They connect the keyboard platform to the track, and allow it to move back and forth and vertically, swivel, and tilt to fit your specific needs. They use a 22" track to easily slide out to a comfortable position for work or underneath the desk when not in use. The tracks are extremely stable and the durable steel construction allow sure keying and mousing. They are set to allow adjustability within a safe operating range.
The difference between the 5G and the 2G is the tilt mechanism. The 2G is the older of the two mechanisms. It tilts by way of loosening the knob, raising or lowering the platform into place and then tightening the knob again to lock it. It also does not list the degree of tilt the platform is adjusted to for reference. We tend to recommend the 5G or 6G for most users. Both of the newer mechanisms tilt with a "dial-a-tilt" knob, allowing the user to adjust the pitch with an easy twist of a knob.
The 6G mechanism is Humanscale's newest offering. It features the same dial-a-tilt adjustment as the 5G with the added benefits of being slimmer and lighter. This gives maximum knee clearance, minimizes the amount of resources needed to manufacture it and gives it a sleeker appearance.
The clip mouse is the only mouse platform that adjusts in three dimensions to enhance comfort. It can be custom positioned using the height, depth, lateral, and tilt adjustability. Place it on either side of the keyboard for right- or left-handed use. Choose between 8.5" and 10" diameters to fit your workspace.
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!
The Humanscale 900 Keyboard Tray is the ideal add-on for typists who are looking to improve their ergonomic setup by bringing their work closer to them. The Humanscale 900 helps position your keyboard and mouse at a proper height and angle by placing your workspace at elbow height or lower. This also encourages your upper arms to hang comfortably at your side with your hands sloping downwards. With the wrist at a straight angle rather than flexing backwards, strain is minimized on your arms and wrists, greatly improving typing comfort.
