Office Chair Frame Shock Absorption

Admin October 19, 2026

The shock absorption design of office chair frames is primarily achieved through the chair leg shock absorption components, the seat cushion and backrest shock absorption systems, and the dynamic tracking system, with each part working in synergy to enhance comfort and stability.

The chair leg shock absorption components are the fundamental structure for shock absorption in office chairs. The bottom of the chair legs is usually embedded with high-elastic rubber or PU (polyurethane) shock absorption pads. These materials have excellent elasticity and wear resistance. When the chair moves or is subjected to ground vibrations, the shock absorption pads absorb the impact energy through deformation, converting the vibrations into heat for dissipation, thereby reducing the amplitude of vibrations transmitted to the human body. At the same time, their high surface friction enhances the grip between the chair legs and the ground, preventing safety hazards caused by sliding, especially on smooth floors or in scenarios with frequent movement.

The seat cushion and backrest shock absorption systems are the core shock absorption modules. The seat cushion uses high-rebound foam as the main cushioning material. Its molecular structure allows the foam to deform quickly under pressure, conforming to the body's curves and distributing pressure. For example, when sitting for long periods, pressure is concentrated on the buttocks. High-rebound foam can reduce the force per unit area through local deformation, reducing fatigue. The backrest provides support and cushioning through elastic shock absorption elements (such as spring serpentine springs or elastic bands). Spring serpentine springs absorb back pressure through elastic deformation, while elastic bands achieve dynamic support through tension adjustment. The combination of the two can adapt to pressure changes under different sitting postures, avoiding the impact of rigid contact.

Some high-end office chairs introduce dynamic tracking systems to further optimize the shock absorption experience. For example, the DynaCore full-process dynamic tracking system equipped on the Sihoo C300 Second Generation Pro ergonomic chair uses sensors to monitor user sitting posture changes in real-time (such as leaning forward, backward, or sideways) and automatically adjusts parameters such as the backrest angle and seat cushion hardness to form a "full-scenario support closed loop." This design not only improves the precision of shock absorption but also guides users to maintain a healthy sitting posture, reducing muscle fatigue caused by improper posture.

In conclusion, the shock absorption design of office chair frames combines material science (such as high-elastic rubber and high-rebound foam) with mechanical structures (such as springs and dynamic systems) to achieve full-link buffering from ground vibrations to human contact, providing scientific support for long hours of office work.
