The Troubles of Office Chairs
The troubles brought by office chairs are mainly reflected in four aspects: comfort, health, space utilization, and design stability.

Comfort Issues
Most office chairs are designed with a focus on functionality, neglecting ergonomic needs. Insufficient support is a core issue, as the chair back fails to conform to the curves of the back and waist, leading to improper sitting posture over long periods, causing fatigue and even pain, especially for those who need to use computers or concentrate on work for extended periods. Hard seat surfaces lack elasticity, leading to pressure on the buttocks and thighs after prolonged sitting, and even causing localized pain. Some "ergonomic chairs" are equipped with adjustable height and fixed lumbar supports, but their actual support effectiveness is limited: after sitting for more than two hours, the lumbar spine may compensate for misaligned support; sitting upright is required to fit the chair back, or mismatched armrest height and desk surface may lead to shrugging while typing, all of which deplete spinal health reserves. Additionally, excessive seat recline increases pressure on the thighs, compressing blood vessels; improperly designed sacral supports may bruise the sacral nerve, further reducing comfort.
Health Risks
Prolonged sitting keeps the body in the same position, leading to muscle tension and poor blood circulation. Impaired blood circulation in the lower limbs can cause leg swelling, numbness, and even increase the risk of cardiovascular disease. Uniformly purchased "ergonomic chairs" often feature simplified structures such as fixed lumbar supports and non-adjustable seat depths, making it difficult to accommodate individual differences. For example, users shorter than 165cm or taller than 180cm are prone to support failure: shorter individuals may experience "feet dangling + seat depth pressing on legs," while taller individuals face "lumbar support pressing against ribs + headrest out of reach"; women, with more pronounced lumbar lordosis and narrower shoulder widths, are more likely to encounter issues with lumbar support "not fitting" and armrests "hanging in the air," which may worsen lumbar muscle strain with long-term use.
Space and Usage Inconveniences
Office chairs occupy a certain amount of space, which can lead to insufficient space in confined environments, affecting walking or furniture layout. Moving the chair requires time and effort, especially when frequently adjusting seating positions. Additionally, some chairs are not designed with storage needs in mind, occupying extra space when idle and further reducing space efficiency.
Design Flaws and Instability
The wheel design of ergonomic chairs, while facilitating movement, makes the chair an unstable platform. The chair is prone to sliding when changing sitting positions, requiring frequent leg and foot effort to reposition it, and the force exerted by the legs and feet while sitting is concentrated on the waist, potentially causing additional pressure on the lumbar spine. This design flaw not only affects the user experience but may also indirectly lead to lumbar injuries.
