How much influence do desks and chairs have on children?

1. Spine and bone health
‌Scoliosis and deformation‌

The mismatch of the height of the table and chair will force children to form bad sitting postures such as hunchback and scoliosis. Long-term effects can easily induce cervical spondylosis, lumbar disc herniation and chest deformation.
When the chair is too high and the feet are suspended in the air, the pelvis tilts forward and compresses the "zongjin area", which may cause problems such as back pain and physical decline in adulthood.
‌Bone joint pressure‌

When the table is too high, the shoulders continue to exert force, increasing the risk of shoulder and neck muscle strain; if it is too low, it will cause excessive forward flexion of the trunk, aggravating lumbar pressure.

2. Vision damage
The imbalance between the table and the line of sight will shorten the distance between the eyes and the book, causing long-term visual fatigue. The phenomenon that the myopia rate of domestic adolescents exceeds 70% is highly related to this.
Frequent head angle adjustments caused by incorrect sitting posture further accelerate the development of myopia.
