Twist Chair
Here's a great product to ensure that you'll never be invited to somebody's backyard ever again. Instead of having four legs like regular chairs, the Twist uses a corkscrew base that you plug into the ground and spin until it's solidly placed. Bring the chair along the next time you go to a garden party and see if your hosts appreciate you aerating their lawn.
