Style RITSUYO MTG Pelvic Support Chair Black This is a listing for the main unit only. The condition is good. There are no problems with use. This authentic posture care seat "Style RITSUYO" makes floor sitting easier on your lower back and legs with the "standing posture." It's an agura (cross-legged) and seiza (kneeling) seat born from chiropractic theory that transforms your usual floor sitting into a comfortable standing posture for your back and legs. ■ Supports the standing posture with 3 functions 1. Standing Curve By raising the position of the buttocks, it guides the pelvis, which tends to tilt backward, to the correct position, and maintains the pelvis in the correct position without having to exert force on the abdomen. 2. Body Trace Surface It disperses the body pressure that concentrates locally and stabilizes the left and right balance of the pelvis. 3. Double Urethane Structure 〈Surface Urethane〉 Softer than the core material urethane, it disperses body pressure while maintaining the inclination angle, making the sitting comfort comfortable. 〈Core Material Urethane〉 Firmly maintains the inclination angle to support the pelvis.
