Animation for Ergotron 24-390-026 WorkFit-A LD Monitor Workstation with Keyboard


Ergotron WorkFit-A 24-390-026 is an affordable workstation that lets a computer user alternate between sitting and standing while working. This model is designed to support light weight monitors (5-15 lbs). Changing your position from sitting to standing offered by this product is increasingly recommended to maintain a healthy posture and thereby prevent medical problems like diabetes, high blood pressure and cardiovascular diseases along with musculoskeletal injuries like carpal tunnel syndrome and tendinitis.

Workfit-As are installed at the back of the desk clearing valuable desk space in the front. When the computer is not in use, the entire assembly of this WorkFit-A can be moved to the side and the keyboard tray flips up 90 degrees. It has a suspended keyboard which drops down up to 4" below the desktop surface for neutral positioning of the hand. 24-390-026 is especially valuable for users who have to work on a computer for 6 hours or more per day.

Featuring an unprecedented range of motion for a standing desk solution, WorkFit-A let’s you swing your computer system left, right, up or down to wherever you need it. Premium ergonomic benefits include keyboard placement below desktop height when sitting and independent monitor positioning.

The height-adjustable arm moves the keyboard and monitor in one simple motion, allowing you to easily sit down or stand up as you work. Fold the keyboard up and push the arm out of the way when you need your desk surface. Includes several installation options to best fit your space.

Had a few issues, Feb 16, 2016
by Deborah T, California
This is the seventh Workfit A we have purchased for our office, and the third with the Tall User's Kit. The ergotron is not working as we can only use it at desk level. The unit will not stay up. The extension kit was not originally shipped and we had to call to make that happen. Not the usual experience with Ergodirect or our Ergotrons!!

Ergotrons are fantastic!, Oct 27, 2015
by Deborah T, California
We have purchased several of the Ergotron Sit/Stand stations, both the pillar style and the very adjustable swing-arm style. Our staff members absolutely love them. Once we start using them we find that we really don't enjoy sitting all that much!!!
