腰へ負担がかかってくる。When a person takes a sitting position, the lumbar spine is burdened due to the structure of the spine. In a conventional chair, the back of the seat portion is made S-shaped or the seating portion is inclined. As a result, the muscles are relaxed and relaxed because they fall into such a chair form, but in the case of conventional chairs that originally support the hips, the burden on the hips is eventually increased.
