Office Ergonomics Workstation Accessories Keyboard Tray Keyboard Trays by Shape Natural Keyboard Trays Humanscale 100 Combo Keyboard Tray SystemThe Humanscale 100 Combo Keyboard Tray System design ensures that users will type and mouse within a neutral reach zone, creating a safe, comfortable and sustainable work environment. The neutral zone in a standard office workspace is defined as the area where a user sits and works at a desk and can easily reach and interact with surrounding computer accessories, including a keyboard and mouse. Unlike older generation keyboard and mouse solutions, Humanscale keyboard trays are designed to ensure that nearly all users are able to work consistently within their Neutral Reach Zone, and thus maintain a low-risk posture.

Video Review - Humanscale Keyboard Tray Systems
Check out our video review of the Humanscale Keyboard Tray Systems below.
Mechanism - Humanscale 100 Keyboard Tray
Three popular Humanscale mechanisms are available.
The 5G and 6G mechanisms are Humanscale's newest keyboard tray mechanisms and are built for maximum stability durability. They feature:
- Easy, knob-free height adjustment with a range of 5" below the work surface to 1 1/4" above the work surface
- 360° swivel
- Dial-a-tilt platform allows you to set a negative tilt from 0° to -15° , accommodating the negative tilt highly recommended by most ergonomists for safe keyboarding
- Platform stows completely underneath the work surface with the standard 22" track
- The 6G is the newest mechanism that is slimmer and uses less material for production than the 5G
6G Specifications
| Height adjustment | 6": 1.25" above track to 5" below track |
| Track length | Comes standard with 22" track |
5G Specifications
| Height adjustment | 6": 1.25" above track to 5" below track |
| Track length | Comes standard with 22" track |
The 2G mechanism offers the same range of adjustment but doesn't include the dial-a-tilt feature. 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. This is a great choice if you're seeking to save some money without sacrificing quality or function.
2G Specifications
| Height adjustment | 6.25": 1.25" above track to 5" below track |
| Track length | Comes standard with 22" track |
Mouse Platform - Humanscale 100 Keyboard Tray
Choose between either the 8 1/2" high clip mouse or the 10" diameter high clip mouse. The clip mouse is their most popular mousing platform since it is the most versatile, allowing you to slide the platform forward or back, swivel it over your keyboard/numeric pad, adjust the tilt or switch from the right to left side of the keyboard platform without the need for tools.
Allowing the mousing platform to swivel over the numeric pad area on your keyboard allows you to move your mouse closer to your body and into the neutral zone which is healthiest for mousing and reducing the stress on your shoulders. Most users will be happy with the 8 1/2" diameter mouse platform, however a 10" diameter is available for those who need a larger surface.

Professor Ergo's Thoughts:
A keyboard tray is a key component of an ergonomic workstation. Position your keyboard tray so you can type and mouse while keeping your wrists straight. The ideal height for the keyboard is at elbow height or lower. Typically you should locate the keyboard tray just above your lap height. Your upper arms should hang comfortably at your sides as you work. The keyboard tray should be gently sloped or tilted away from the user to allow the wrists to be straight instead of flexed. When properly adjusted, a keyboard tray allows the back, neck, shoulders, and wrists to relax. The size of the keyboard tray must accommodate the keyboard and any input device like a mouse. Avoid having your keyboard on a tray and your mouse on the desk.

Our Customers Say ...
I received the chairs today and they are perfect. Thank you for your personal attention to my shipping snafu. In this day and age of the internet and push button instant gratification, we sometimes forget that the real value is not in a price that is 1% better. It's in the value added by empathetic people how really try to help. Maybe you should create a company tag line like "Real humans providing great human solutions."
