This Standing Desk Converter is amazing! I had a separate stand-up desk but found it so inconvenient to keep moving my monitors, laptop, cords and keyboard from one place to another. This converter worked perfectly in that I'm able to place it right on top of my desk and either use it as a platform for my monitors when I'm sitting down or I can use the lever to stand up when I feel like it.Pros:- It arrived in the expected time and was as advertised on the website.- It was very easy to set up.- The 37” work surface is wide enough for my two 17” monitors and 13” MacPro- The keyboard tray is also wide enough for a full keyboard, the mouse and my calculator- The gas spring works very smoothly and can be easily adjusted- The quality is great and worth the priceCons:- In the collapsed state, the workspace sits up about 5.5 inches, which puts my monitors up a little higher than I’d like. I find myself cranking my neck up when I sit.Helpful hints:- The desk is pretty heavy so you may need someone to help you put it on your desk.- Purchase an anti-fatigue mat with this! This will help your feet when you’re standing up. I purchased the Sorbus Anti-Fatigue mat with this and it is working well so far.- Per the 2nd picture, if you have a pull-out keyboard tray on your desk, a wireless keyboard and mouse makes it easy for you to move it back and forth between the sitting and standing position. Not to mention, it’s so much better ergonomically to have a keyboard tray when you’re sitting!
