Reddit reviews Stand Up Mat for Standing Desk, Comfortably Stand for Hours While Significantly Reducing Upright Stress on Your Back, Hips, Knees and Ankles. It is a Comfort Mat and an Anti Fatigue Mat

Good morning /u/DaOpa!

I have a motorized BEKANT desk from IKEA (http://www.ikea.com/us/en/catalog/products/S49022538/, very similar but it doesn't show the actual controls to move the desk up and down in the pictures). I absolutely love the desk. While it's a complete desk replacement and not a piece that sits on top, it might not be an option for everyone. The desk itself has a net under for some cable management. If you plan on doing this, you might want to look at longer cables to ensure that there is no tension on any of your devices in any position.

If you're wanting a standing desk for ergonomics, ensure that the height will work for you with your arms around a 90 degree angle. You don't want to be slouching or leaning over constantly as it's going to defeat the purpose. I still find myself doing it from time to time though. Another option to consider is also the height of your monitor, as looking up or down for too long will strain your neck.

If you're standing for a long period of time, I'd recommend a Standing Desk Mat. This should help your back for those longer playing sessions. Here's a link to a similar one to mine, but I'd recommend doing your own research on whats best for you. https://www.amazon.com/Standing-Comfortably-Significantly-Reducing-Upright/dp/B00R89CZKO

If you have a green screen, consider the height of the green screen, how tall you are, and how far away your camera will be. This might be a deciding factor on if you actually play standing up or not, as for me my Elgato Green Screen was too far back and I had little room to crop the top of the webcam without clipping my head.

Hope this helps!

if she is standing, she should probably invest in a cushion mat as well https://www.amazon.com/Standing-Comfortably-Significantly-Reducing-Upright/dp/B00R89CZKO
