Animation of Ergotron 24-312-026 WorkFit-A, Dual Monitor Sit-Stand Workstation


Ergotron 24-312-026 is an ideal solution for corner workstations. This WorkFit-A clamps to rear of the desk, clearing space in the front. You can fold the keyboard up and swing the arm out of the way when you need your desk surface for non-computer work.

This workstation comes with dual benefits - its lets you alternate between sitting and standing at work and it has two displays. Both these benefits together provide ergonomic relief as well as increase productivity.

Ideal for corner workstations or confined areas, WorkFit-A attaches to the rear or side of most surfaces while keeping the keyboard upon the desktop when sitting. Featuring an unprecedented range of motion for a standing desk solution, you can swing your system left, right, up or down.

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. With its extra vertical reach, this model is well suited for taller users.

I have been purchasing this product for our company for a couple of years. Every unit, after install receives high compliments on its ease of use, solid construction and quick adaptability from the end user. From the installer, it does takes some time to adjust the bottom bracket under the top surface, afterwards installation is very smooth. Full install with attachment and cabling in place takes about 90 minutes. Highly recommend this to anyone thinking of purchasing this excellent adaptive sit-stand component for any workstation surface.

Feeling GOOD, Apr 8, 2016
by Cary Jenkins, Logan, Utah
I'm giving this product a 5 because standing more often has helped with my back, knee and hip pain. I no longer experience these pains like before when I was sitting for 8 hours a day. The ability to go from sitting to standing with no effort at all is a huge benefit. The workstation was fairly easy to put together. The only problem I had was tracking down a 1/4 socket wrench.

Everyone is jealous, Dec 15, 2015
by David C, Florida
It's great for standing, however at the sitting position the screens are a little high. It would be nice if you could adjust screens to the desired height. It is very difficult to put together and the instructions are horrible for figuring out the tension. I didn't like that the grommet piece I ordered came separately, so after I built the station I realized the grommet wasn't included so after I had attached the computer screens I had to take it apart again until I got the grommet in order to actually use it.
