Laptops: when actually placed on one’s lap they overheat the thighs as well as causing arm fatigue and backstrain.
Today’s invention is a mini lecturn made of recyclable cardboard which reduces both these problems, by placing the screen and keyboard in a more comfortable position.
The lecturn would be made in a single, foldable sheet.
Held firmly in place by sitting on the flaps, the ‘column’ on which one’s machine (or book, if you prefer) rests can be adjusted by tearing off sections along perforated lines in the cardboard at a number of different possible heights (and/or angles).
