With the disc issues in my neck I began noticing that sitting was the worst thing I could do. If I was on the move all day then my leg rarely started burning but if I sat down for more than about 45 minutes the burn would come on and once it came on it rarely went away for the rest of the day. The most time I would spend sitting was at the computer which is where my worst bad habits of leaning forward and slouching come into play. So I decided to change up my workstation a month ago and bought a stand-up desk unit. With my old school 27″ iMac I was rather limited by weight as to what would work but the Ergotron Single HD unit would hold my system. I opted for the one with the extra shelf so I’d have room for my collection of input devices since I’ve gotten oddly used to using a pen tablet, touch pad and mouse.
