Office Chair with Low Backrest

A low backrest on an office chair can have adverse effects on the spine and muscles, but these can be improved through certain methods, and the price range for such chairs varies widely.

Problems Caused by a Low Backrest

• Lumbar Suspension Leading to Strain: A low backrest fails to conform to the curvature of the lumbar spine, requiring the lumbar muscles to exert continuous effort to maintain body balance. After sitting for half an hour, tiny tears can occur in the lumbar fascia, which may develop into chronic lumbar muscle strain over time.
• Cervical Spine Forced to Lean Forward and Bear Pressure: When the backrest height is lower than the scapula, the body will involuntarily lean forward to find a support point, forming a "turtle neck" posture. This posture causes the cervical spine to bear 2 - 3 times the weight of the head, making white-collar women prone to neck stiffness and headaches, and potentially affecting bone development in adolescents.
• Formation of Habitual Incorrect Postures: A low backrest can easily induce compensatory postures such as crossing legs or leaning on one side. Research from Tsinghua University shows that if this posture persists for more than three months, the incidence of pelvic tilt increases by 47%, and it may lead to initial symptoms of scoliosis.

Solutions

• Heighten the Headrest: Purchasing a computer chair with a heightened headrest can elevate and support the neck, preventing excessive pressure on the cervical spine. If the neck feels a bit empty when first using it, placing a small pillow can enhance the effect.
• Lumbar Support: Using a lumbar pillow can relieve lumbar fatigue and prevent lumbar muscle strain.
• Adjust Posture: Try to keep the upper body straight and both feet flat on the ground to reduce pressure on the cervical spine and lumbar region.

Price Range

• Around 100 Yuan: Chairs with a low backrest made of ordinary materials and simple craftsmanship, such as plastic or simple wooden materials, are suitable for temporary use or scenarios with low comfort requirements.
• Several Hundred Yuan: Medium-quality chairs with better fabrics and metal frames, such as simple office chairs or staff chairs, are priced between 235 - 300 Yuan.
• Over 1,000 Yuan: Some chairs with a low backrest that have a strong design sense and are made of high-quality materials, such as premium leather and exquisite metal components, may require a budget of several thousand Yuan.
