Professor Ergo's Thoughts:

The Knoll Act II Keyboard Platform features a swiveling mouse platform that can be mounted on the right or left side, and is also available with dual mouse platforms to accommodate multiple users or ambidextrous mousing. We recommend switching between your left and right hand to mouse periodically in order to combat or prevent repetitive stress injuries.

Our Customers Say ...
  • Completely satisfied with the desk. More impressive was the buying process, knowledge of the sales and support staff, and attention to detail. It's clear that this company is on a mission to help people. They have found a way to differentiate themselves in a crowded market and stand out as a great company which deserves all the success it achieves. We will be adding a second UpLift 900 in the near future. Thank you!
