Abstract
A chair has a seat portion and a leg portion. The seat portion and the leg portion are joined by a structure that allows that seat portion to wobble relative to the leg portion. The structure can include one or more resilient member to create the wobble and one or more motion restrictor member to limit the amount of wobble or prevent wobble.
