Humanscale 900 Tray

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.


Keyboard Support


In many ways, a keyboard support is the heart of an ergonomic workstation. As reach and vision drive posture, our keyboard tray allows the user to sit in a healthy, neutral posture through bringing the keyboard and mouse to the user in an ergonomic position.

Well Designed


A well-designed keyboard tray offers protection from carpal tunnel syndrome, neck and back pain and other musculoskeletal issues.

Postural Benefits


These postural benefits can’t be achieved by just using a keyboard on a height-adjustable work surface.

VERY STURDY AND WELL CRAFTED

I've tried a few other keyboard trays and they were all lightweight and flimsy and I was always afraid to put much weight on them for fear of them falling apart. This tray is sturdy and the mouse pad is great because you don't have to squeeze everything onto one tray.

Great product, well made but expensive new. Suggest a used unit as there is not much to the unit...

Nice tray, and used was the best way to go. I think Humanscale products are well made but expensive for what the product actually does. I made a slight mod to the mouse tray by drilling a small hole through the keyboard main tray and the mouse pad and inserted a locking pin to keep the mouse pad more stable during use. Other than that I am completely pleased with the unit and enjoy being able to sit stand with the articulated keyboard.

THE BEST in my 20+ year use experience

I've had mine for over a decade. I've purchased many others for my wife and in other situations -- none come close. Mine has held up incredibly well. It has a solid feel. I only found this on here today because it's starting to fade and I wanted to see if they were still being made.

Overpriced...

I ordered this for a client. My feeling was there are alternatives for $100 less that would have suited, but this is what they wanted. I deducted a star for missing hardware...this thing only came with 10 round head screws...no flat head screws...no rubber bumper for the back. I deducted another star just for the humanscale hype...ugh. It is really just okay. I am generally a pretty positive reviewer and give tons of five star reviews...this one just got on my bad side with the missing hardware and it was downhill from there.
