The back beam of the yoga chair has one beam and two columns. The back beam of the yoga chair is a horizontal bar to support the backrest and seat of the chair. Some yoga chairs are designed with two columns fixed at both ends of the back beam, which can increase the stability of the chair and make the practitioners safer when doing handstand and handstand exercises. In addition, this design can make the yoga chair more beautiful and more ergonomic. Therefore, the design of the back beam of a yoga chair with one beam and two columns is mainly to increase stability and aesthetics and better meet the needs of practitioners.
