Ergonomic Chair

摘要

A chair having a contoured seat cushion mounted on top of an exercise ball with four tension-adjustable elastic cords such as bungee cords is provided. The shock absorbing cords may attach to the underside of the seat cushion by looping through spring-eye carabiner type hooks, and may pass through grooved locking tubes with v-channels for adjusting the cord tension. The ball may sit on top of a swivel plate, so that dynamic motion and counterbalancing are attainable for a variety of ergonomically beneficial seating styles.
