My treadmill desk, built from a $400 walmart treadmill, pieces of my former Ikea 'Jerker' desk, and a $30 metal shelf from Costco.<p><a href="http://letterblock.com/images/treadmill_desk.jpg" rel="nofollow">http://letterblock.com/images/treadmill_desk.jpg</a><p>So obviously I can do walking at various speeds and inclines (usually 2 mph at 4 degrees) or standing. I have an ergo standing mat that I put on top of the treadmill if I'm going to be standing for a bit. Whenever I get the rest of this office cleaned up enough, I'll look for a small easy chair for occasional resting or iPad use. Off camera there's also a stand fan, which you may need if you walk for hours and your office window faces south in Florida. (My office has always been hot, and I find that moving actually makes it more bearable.)
Another cheaper option is a standing desk with a high office chair. I used one of these for about two years and it did make a positive difference. You can stand or sit and it costs no more than a regular desk. (My workplace uses desks from Ikea, they are cheap and comfortable)<p>Unfortunately, I like to switch between 'sit', 'stand' and 'slouch'; slouch being reserved for when I'm really "in the zone". I missed that option and eventually went back to a sitting desk. I'd love to try one of these mechanical ones.
I made this site, trying to build a useful buying guide.<p>I'll be in and out, but feel free to ask any questions here or through the contact form on the site. I'll try my best to get back in a reasonable time frame.<p>I'd also appreciate any feedback on the technical/marketing aspects of the site.<p>Thanks! Ben
