When sitting, then elastic-sprung!

The elastic-springy buffer zone of the seat cushion activates the sitting posture. The rebound effect causes a reciprocal tensing and relaxing of the gluteal muscles. The seat cushion is the perfect complement to dynamic standing. The German Association “Aktion Gesunder Rücken” (AGR) has tested the kybun Joya seat cushion, awarded it the AGR seal of approval and recommends it as particularly back-friendly.
