Why is this not a thing already?

You rock the chair.
The chair generates electricity enough to light the book you are reading, or play a lullaby, or charge your lap-top, or... activate a stopper if a cats' tail is detected.

...or build up sufficient charge to rock the chair automatically for a little while and save you the trouble [+]

That I like.
You rock yourself to sleep and the chair rocks you for a while after you've nodded off.
Brilliant.
