I still use my laptop regularly to watch TV in bed. This looks like a great way to position it perfectly. Slip in underneath it, slide out when you need to and place it in the perfect position for either sitting, reclining or lying down. It is such a simple idea and low risk – if it falls, it either falls on the bed or in your lap, no harm done, to the laptop at least.
“Ten minutes, two hooks, and some string. That’s all you to need to make this marvel of laptop holder engineering.”
Screw two hooks into the ceiling, attached a looped piece of string to each hook and insert your laptop into the loops. When done, remove the string and stash in a drawer.
