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.

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.

Professor Ergo's Thoughts:

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.

I would recommend this item to a friend.

I needed this a year ago
September 23, 2015
This is an amazing product. I had used a standard keyboard tray for 10 years, and at night my hands and wrist were so sore and ache. It hasn't happened once since I started using this system. I must say, for paying $300 for a keyboard tray, I really expected much, much better instructions on how to install it. It took me about 90 minutes, after two trips to the hardware store. And when I chatted about some "extra" parts I ended up with, the online person referred me to another phone number to call HumanScale. So even though this is a great product, the rest of the process could sure use some work.
Very comfortable and adjustable. The mouse tray is outstanding.
Now I sit two feet back from my computer screen and desk. I really wasn't ready for that. I feel like I need a telescope to see my computer screen.

Good Product

I like this tray, but am a bit disappointed that the design does not work better with the Human Scale Float table. The keyboard tray does not push under the table. Also, installing it onto the Float Table was a bit difficult and frustrating. Make sure that you buy the UpLift 920 desk that doesn't have a crossbar beneath the desk if you want to mount a long track under the desk; this will allow you to push the tray all the way under the desk when it's not in use. Many people leave their tray out all the time though as you always need your keyboard and mouse if you use your computer so this isn't a big issue for a desk if it's used as a computer workstation most of the time.

This tray works as described. It is very sturdy and adjustable. I only wish it tilted down.

Excellent product
July 13, 2010
I am using the HS 900 keyboard tray with the Kinesis freestyle split keyboard and it is working great for me. Prior to purchasing both products I was using MS keyboard positioned on my desk and had lots of stiffnes and pain in my wrists and shoulders. I always hated the traditional keyboard trays but with the help of articles on the HS website I realized I needed a narrower footprint for the keyboard and the tray. HS's customer service is excellent and the online chat feature is also very quick and helpful.
