I work at home. In my bedroom. My gamer computer has a couple monitors, but the big one is the 43 inch TV, pointed right at my bed. After all the meetings are done for the day, and most of the complicated stuff is over with, I move to that computer and relax there propped up on pillows with my keyboard on my stomach, mouse on another pillow, perfectly reclined, much like this guy with all his gear, except I don't need assistance removing myself.
... but ... that has to be some photoshop shit. It looks like the xray machine at the dentist office with some monitors attached. Probly radioactive.
I'd get tired of picking the mouse up off the floor. Wonder how long it would take for me to learn to not drop it - like an astronaut just back from the space station.
I used Velcro on a mouse for a slightly different configuration and it worked pretty well, but it was a trackball. Had an apron that I stuck my mouse and split keyboard on so they could be used sitting, standing, seiza, cross legged, etc.
Not sure why you are downvoted. This has to be terrible for your body. Maybe unless you have some very specifc spinal issue or something like that I guess?
