Japanese Ergonomic Office Chair
A typical example of Japanese ergonomic office chairs is the 'ing' office chair launched by Kokuyo Co., Ltd. It alleviates health issues caused by prolonged sitting through dynamic design, offering both exercise effects and brain function enhancement.
1. Core Functions and Health Benefits
The 'ing' office chair is equipped with a sliding mechanism beneath the seat, enabling 360-degree free tilting functionality that supports unconscious movements such as leaning forward, backward, and swaying side to side. This design mimics the dynamic balance experienced on horseback, surfboards, or while cycling, reducing the burden of prolonged sitting by distributing body pressure. Tests indicate that four consecutive hours of use equate to the exercise effect of walking 1.5 kilometers (approximately 85 kcal burned), effectively alleviating muscle stiffness and poor blood circulation caused by prolonged sitting.
2. Scientific Basis for Brain Function Enhancement
Dynamic seating design positively affects brain activation. In a 60-minute reading test, 70% of participants showed an increase in alpha waves (associated with relaxation) in the brain, while 60% demonstrated an increase in beta waves (linked to concentration). This suggests that unconscious movement may stimulate the secretion of neurotransmitters in the brain by activating the vestibular and proprioceptive senses, thereby enhancing attention and creativity, particularly suitable for office scenarios requiring prolonged focus.
3. Design Philosophy and Product Positioning
The product is defined as a 'combination of a chair and a balance ball,' inspired by the principle of dynamic balance. By integrating the instability of a balance ball with the supportive function of a traditional office chair, it maintains sitting stability while introducing a micro-movement mechanism. This design not only addresses sub-health issues caused by prolonged sitting but also won the Silver Award at the 2019 China Design Intelligence Award, validating its innovation in the field of industrial design.
4. Market Application and User Feedback
Currently, the 'ing' office chair is available on the market, primarily targeting groups that require prolonged desk work, such as programmers, designers, and students. Its dynamic adjustment function does not require active user operation, seamlessly integrating into the office workflow and reducing the risk of interrupting work rhythm due to deliberate exercise. User feedback indicates that long-term use significantly improves lower back pain and enhances mental state during work.
