Description

Technical Field

[0001] The present invention relates to the technical field of office desks and chairs, and specifically to an ergonomic office desk and chair with multi-functional posture adjustment. Background Art

[0002] At present, sitting at a desk for a long time has become a common phenomenon, but poor sitting postures are likely to cause health problems such as cervical spondylosis, lumbar disc herniation, and shoulder and neck muscle strain. Although existing office desks and chairs have introduced ergonomic designs, such as functions of adjusting the seat height, backrest tilt angle, and armrest support, they still have the following defects: 1. The adjustment method is single and lacks intelligence: • Adjustment of existing office chairs requires manual operation, and users often neglect the adjustment due to laziness or inconvenience, resulting in maintaining a poor sitting posture for a long time.

[0003] • It cannot provide personalized adjustment according to individual body types, habits, or health needs.

[0004] 2. Lack of real-time posture monitoring and feedback mechanism: • Existing office chairs cannot detect whether the user's sitting posture is correct and cannot remind or actively intervene in the adjustment.

[0005] • If users maintain an incorrect sitting posture for a long time, it may cause spinal injuries without their knowledge. Summary of the Invention
