Product Description

The Humanscale Keyboard Tray with Flat Mouse is a great keyboard system that’s fully adjustable. This keyboard system includes Humanscale’s popular 500 Series Keyboard Tray and also comes with Humanscale’s best-selling 6G Keyboard Tray Arm. The main difference between this keyboard tray system compared to other Humanscale tray systems, is that the Flat Mouse system has an extra-wide tray which is 8” wider than standard. This makes adding a separate mouse tray unnecessary, since the mouse can be placed directly on the tray itself.


Design Story

An ergonomically designed keyboard is essential for every workstation. Ergonomists agree that the healthiest typing posture is one that allows the wrists to maintain a neutral or slightly pronated posture – straight or bent at a slightly downward angle. For that reason, Humanscale designers created our under desk keyboard trays, which allow the keyboard to be ergonomically positioned anywhere from 0 degrees to a -15 degree angle.

Humanscale Keyboard Tray System with Flat Mouse - Options

Palm Rest

  • Foam Palm Rest - Standard foam palm rest
  • Gel Palm Rest (+$10.00) - Humanscale’s “Technogel” technology has a softer feel than foam and distributes the weight of your palms over a larger surface area, minimizing the pressure you feel against your palms.

Track Length

The track attaches to the underside of your table top, and the keyboard tray attaches to the track.  Provides extension and retraction of the keyboard; available in 18" or 22" lengths.  Please measure the underside of your table top to determine which track you should order.

  • 18" Track Length – 18" track accomodates most worksurfaces but when fully retracted, leaves approx 4" of the keyboard tray extending past the edge of your desk.
  • 22" Track Length  – Longer track accomodates full retraction of the keyboard, so it is completely hidden from view.  Just make sure you have 22" of clearance underneath.

Installation Guide


Not having a keyboard tray system forces you to work around your keyboard. Your keyboard is in a fixed position (on your desk) and you have limited adjustability, especially when it comes to keyboard height and keyboard slope. Not to mention, the keyboard takes up valuable desk space too - so it’s hard to keep your paper work in front of you.

There are several advantages to using a Humanscale Keyboard Tray with Flat Mouse System. Adjustability is a big part. You can adjust the height of the keyboard tray with a 7” adjustment range - you can raise the tray 1.5” above the track or lower it 5.5” beneath. You can adjust the slope of your keyboard tray as well. Modern ergonomics says you should actually have a negative slope while typing (when the top of the keyboard is angled lower than the bottom of the keyboard). The Humanscale Keyboard Tray with Flat Mouse System provides up to -15 degrees of negative slope and lets you achieve this ideal ergonomic position while typing.

  1. I love this keyboard tray! 5 Star Review

    Posted by on 29th Apr 2014

    My wrist would cramp up from time to time and I’d get carpel tunnel, from bad wrist alignment. I work as a Medical Transcriptionist, so I spend hours every day typing. This keyboard tray is a godsend, you can adjust it up or down, any which way you want and it has made such a difference for me. I highly recommend this product to anyone who types a lot.
