Hi, I'm a bit biased as an investor in, and CFO for, a startup company that hopes to revolutionize the way people work. That said, I have been working at the Focal Upright Workstation (Locus Seat and Locus Desk) with an anti-fatigue mat on the seat base and I LOVE it. Way more energy, focus is not an issue (though I don't think this would be the case on a treadmill desk) and a great relief on the lower back issues that would crop up after sitting all day. Our website www.focaluprightfurniture.com has more info and videos. If you are familiar with Keen Footwear you'll be interested to know that this workstation was designed by Martin Keen who founded Keen Footwear earlier in his career.
