It is an Ergotron rebranded. Solid quality. Only complaint is that the mounting pole is rather short, so you cannot raise the mount very high. Not a problem for me, but others have found it too low.
The Ergotron 45-245-026 mounting arm is made from quality materials for the most part. It is sturdy and has a substantial base which leaves you confident that it'll hold the 2 monitors. You'll need at least 6 - 10 inches from the back of your desk to the wall to be able to use the full motion of the mounting arms.
The WorkFit shipped promptly and matched up with both the Overstock and Ergotron product discription. Assembly was straighforward. I haven't experienced any issues with the workstation and my neck and back both feel better than they have in quite a while.
I purchased the work fit station and this surface attaches to it and creates a great surface to place papers, and other work items right in front of you as you are working. Also it is a handy place to put my coffee. I would definitely recommend this if you purchase the work fit station--it adds function value to it.
