Elastic springy seat cushion

When sitting, then elastic-springy! The elastic-springy buffer zone of the kybun Joya seat cushion activates the sitting posture. The rebound effect causes a reciprocal tensing and relaxing of the gluteal muscles. The kybun Joya seat cushion is the perfect complement to dynamic standing on the kybun mat and wherever standing is not possible. Improved health for the whole body and increased concentration are assured.   Trains the pelvic floor muscles Loosens adhesions in the back fasciae Relaxes pelvic musculator Colour: Black Foam: 100% polyurethane Cover: 100% polyester, washable, non-slip Size: 46x41x9cm   Tested and recommended by: German Association forum Healthy Back – for a better life (Gesunder Rücken – besser leben e.
