Drawbacks of Traditional Office Chairs
The drawbacks of traditional office chairs are mainly reflected in the lack of ergonomic design, insufficient lumbar support, cushion issues, limited adjustability, low comfort, poor blood circulation, and unreasonable armrest design.
Lack of ergonomic design: Most traditional office chairs have a simple design that does not fully consider the curvature of the human spine. They usually only have a fixed backrest and cushion and cannot adjust according to the body's dynamic changes. For example, the lumbar support position of ordinary office chairs is relatively high. When a person leans forward naturally, the sacrum is completely suspended, leading to pelvic retroversion, which triggers compensatory spinal curvature, forward shoulder and neck extension, and restricted breathing.
Insufficient lumbar support: When sitting for a long time, the waist does not receive effective support, which can easily lead to lumbar fatigue and injury. Many office chairs on the market use "ergonomics" as a marketing gimmick but fail to provide even the most basic sacral support, which is the root cause of back pain after prolonged sitting.
Cushion issues: The cushions of traditional office chairs are often hard. Sitting for a long time can cause pressure on the buttocks and thighs, leading to poor blood circulation and a feeling of numbness and soreness. Cheap sponge cushions will collapse and deform within three months, causing a sharp increase in the pressure on the ischial bones. This not only causes numbness in the buttocks but also compresses the sciatic nerve, triggering lower limb blood circulation disorders.
Limited adjustability: Traditional office chairs find it difficult to meet the personalized needs of different users. For example, they cannot precisely adjust the backrest angle, cushion height, etc., making it difficult for users to find a comfortable sitting position. Old-fashioned solid wood chairs are mostly designed with a fixed structure, and the height of the seat and the angle of the backrest are not adjustable. Users cannot make personalized adjustments according to their body shape and work habits, and are easily forced to adopt a single and unnatural sitting position.
Low comfort: Traditional office chairs may not provide sufficient support and may not fit well with the user's back and waist, leading to improper sitting posture, which in turn causes fatigue and discomfort. This problem is more prominent for those who need to concentrate on work for a long time or use a computer for extended periods.
Poor blood circulation: Sitting in a traditional office chair for a long time keeps the body in the same position, leading to muscle tension and poor blood circulation. Poor blood circulation in the lower limbs can cause leg swelling and discomfort and may also increase the risk of cardiovascular diseases.
Unreasonable armrest design: Fixed armrests force the elbows to hang in the air or the shoulders to be raised when operating the keyboard, keeping the trapezius muscles continuously tense. Data shows that 72% of mouse hand symptoms are caused by the mismatch between the height of the armrests and the desktop.
