An office chair that makes you smarter

The Buoy office chair

Designed for particularly restless sitters, knee-bouncers, pencil-tappers and those who've "got jazz hands", the Buoy's an uber-portable, comfortably cushy stool that can sway and spin in every direction without tipping over, providing the freedom of movement that's been shown to keep your mind sharper and more creative.It can also be raised and lowered like an office chair via a built-in pneumatic handle and comes in a slew of striking colorways and patterns (including a few from British designer Paul Smith).
