This Chair Scratches Your Back For You, Slacker

From the Solution Looking for a Problem department comes this gem.

The user, moving a fingertip across a touchpad located under the seat base, controls the position of the scratching actuator and its intensity. According to the scratching on the hidden pad, the chosen mechanical fingernail (connected to a servo motor) moves around the back of the chair and provide the necessary scratch.

I've barely the words.

Looks like a fall waiting for a sudden gust of gravity.
