Bending Degree of Office Chairs
The design of the bending degree of office chairs is mainly based on ergonomic principles, with different suitable bending angles for different usage scenarios and user groups.
Adult Office Chairs
- Backrest Bending Curvature: The backrest has a relatively large bending curvature, aiming to fit the natural S-shaped curve of the human spine. It provides stable support from the shoulder blades, thoracic spine to the lumbar spine, fills the gap in the lower back, shares the weight of the upper body, and reduces the burden on the back muscles.
- Angle between the Backrest and the Seat Surface: According to the national standard 'Ergonomic Requirements for Healthy Homes - Part 3: Office Desks and Chairs', the original reference angle (the angle between the backrest and the seat surface) of an office chair should be between 90ยฐ and 95ยฐ. In actual use, for focused work, it is recommended to set the angle between the backrest and the seat surface at 90ยฐ - 110ยฐ. This angle allows the body to be in a relatively focused and comfortable state, reducing fatigue caused by maintaining a fixed posture for a long time. For relaxation scenarios such as lunch breaks, the angle can be adjusted to 110ยฐ - 130ยฐ. At this time, the body can lean more comfortably against the chair, relieve physical stress, and improve the quality of rest.
Children's Office Chairs
Children are in the stage of physical development, and the physiological curves of their spines have not been fully formed. For children's office chairs, a backrest curvature of generally 100ยฐ - 120ยฐ is more appropriate. This angle range can better fit the physiological curves of children's spines, provide effective support for the spines, and reduce the pressure on the spines in a sitting position. It helps cultivate correct sitting habits in children, prevent problems such as scoliosis, and at the same time allows the back muscles of children to be in a relatively relaxed state, ensuring that children can engage in office activities in a more comfortable posture and promoting their healthy growth.
