คุณลักษณะ

  • BeneS chair cushion type (upholstered) created with the concept of "keeping your back straight."
  • Three-dimensionally fitted backrest and three-dimensional curved seat support your waist firmly.
  • The slightly forward-leaning seat makes the angle between the upper body and thighs greater than 90 degrees, making it easier to stand up the pelvis and maintain the S-shaped curve of the spine. When sitting, the area around the ischium sinks down to support the entire buttocks with the unique "ischium pocket," making it easier to have a good posture.
  • Automatic locking strength allows small women and large men to automatically detect their weight and achieve ideal locking strength.
