As you can see my desk is not static.
Any bed can easily become my desk. The location of my desk usually depends on the weather. If very cold like today (snow) then it is necessary to move to the spare room which is a couple of degrees warmer than my usual room which today is like a fridge. The method of working at a moveable desk merely involves being a. flexible (although not in a yoga type way) and b. happy to strew required items on any available surface that is within arm's reach of laptop and then hunkering down with laptop on lap (funnily enough.)
