Keyboard Platform

The 900 and 950 keyboard platforms are both made of phenolic resin. Most people prefer the 900 board, but the 950 is available for users desiring a narrower platform.

  • 900: 19" W x 10.625" D
  • 950: 19" W x 8.4" D

Lateral Slider

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.

Track Length

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 6G mechanisms is 22 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.

Mouse Platform - Humanscale 900 & 950 White Keyboard Trays

Clip Mouse - Mousing Platform

Humanscale Clip Mouse

The clip mouse platform is the only mouse platform that allows the user total adjustment control in all three dimensions- height, depth, forward/back and tilt, allowing it to be adjusted precisely the way you need it. It also easily snaps onto either side of the tray for left or right use, and it's available in two sizes and different height ranges.

Note: The high clip has an extra one inch height for additional adjustment and usability and is the most popular accessory we sell.

  • 90: 8.5" diameter
  • 90H: 8.5" diameter high
  • 91: 10" diameter
  • 91H: 10" diameter high
  • 90H90H: 8.5" diameter high - Dual platforms for left and right
  • 91H91H: 10" diameter high - Dual platforms for left and right

Swivel Mouse - Mousing Platform

Humanscale Swivel Mouse

The swivel mouse mounts underneath either the left or right front corner of the platform. It swivels out from underneath the keyboard platform easily and tucks out of the way when not in use. This mouse platform is available in right, left and dual configurations. The main difference between the clip mouse and swivel mouse is the adjustability. The swivel platform stays on the same tilt or angle as the keyboard tray; the clip mouse angle can be adjusted independently.

  • 11R: 8" swivel right
  • 11L: 8" swivel left
  • 11D: 8" swivel dual
  • 12D: 10" swivel dual
  • 12R: 10" swivel right
  • 12L: 10" swivel left

Humanscale's brand new 6G mechanism is designed with an ultra-thin profile and is light weight. Its size makes it attractive, compact, easy to move and gives maximum knee clearance. Additionally, the 6G keyboard tray mechanism's dial-a-tilt adjustment makes it one of the easiest and most intuitive systems available.

Humanscale 900 and Humanscale 950 keyboard platforms work with the adaptable clip mouse platform, which can be placed on either side of the keyboard tray for use by right- or left-handed individuals. The mouse platform articulates separately from the keyboard platform, so the mouse rests on a flat surface to avoid sliding off, even when users tilt their keyboard for comfort.

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.
