I built this from an old exercycle, an office chair, and some steel I scored from work. I wanted something that was custom made to suit me so I mounted a chair to the old exercycle frame and built a desk around myself. I used the desk in its previous incarnation for a year and it worked fine but there was a lot of tidying up to be done, so when we shifted to a nicer house I decided to upgrade the desk so I didn't feel so bad keeping it in the lounge. The footrest comes up at the same time as the desk comes down, the springs underneath are to help with the weight of the desk. Here it is in the open position The keyboard is held on by magnets I have glued to the bottom and there is a metal plate on the desk to hold it in position, that way I can still move it around for comfort. I am making a side table now so that I can keep my mouse cradle, USB hub, volume controls, iPhone dock and a place for my coffee. The table will also enclose my PC, so I guess it will be a custom case when it is finished. I have more info on my blog at geek2green.blogspot.com More pictures here http://imgur.com/a/dMwCO Also the evolution of the chair (10 videos) is at http://www.youtube.com/playlist?list=PLC4BF16ECBAF8F4F6 I will do a video of the finished desk working soon but I was in a traffic accident on my scooter and I am a bit messed up right now. Please feel free to ask any questions or make comments. I know the whole idea is wacky but it works really well for me. Cheers.
