If you won’t make the effort of going to the study, you might as well bring the study to you. If your bed room space permits it, accommodate a set of table and chair.
For those of you who would not make that effort either, or if your bed room is not spacious enough for a table and chair, get a lap table. Keep it accessible from your bed, and it will be your desk in bed. Working on a flat and sturdy surface will inspire motivation to work.
The most essential role will be played by lighting. Get enough lighting fixtures in your bed room, especially over-head. Generally bed rooms have subtle lighting, but working requires substantial illumination. The brightness will also keep grogginess at bay. If your bed is placed against windows, daytime light will be plenty.
You might want to keep some sturdy back supporting cushions around. These will come in handy when you want to switch from relax-mode to work-mode. A strong back support will instil more inclination towards work over a comfortable bed pillow.
These simple hacks will give a renewed definition to the modern-day concept of work-from-home.
