Problem statement: To make using your laptop in bed more comfortable.
Primary Needs:
1) The stand is convenient to use.
2) The stand is easy to adjust.
3) The stand is compact.
4) The stand is multi - purpose.
5) The stand is pleasing to the eye.
6) The stand is portable.
7) The stand is economical.
These are the three concepts that I chose to make prototypes of according to my selection matrix.
Concept A - Screw pivot top with screw clamping legs (leg screws not shown), legs are infinitely height adjustable in this prototype.

Laptop in place, legs fully raised, and top tilted slightly.

Without laptop, legs retracted, top in horizontal position.
Concept D - Heat conductive top with a built-in drawer for storage of stationery (or anything else that fits).

Concept E - Top with built-in stationery bins and cooling slots.

This matrix was created to aid selection of a design concept that so satisfy my problem statement: to make using your laptop in bed more comfortable.
