This utility model provides a highly stable shock-resistant table, relating to the field of table technology. The highly stable shock-resistant table includes table legs, with a horizontal buffer mechanism at the lower end of each leg. The horizontal buffer mechanism includes a base box, within which a movable tube is installed. At least three horizontal spring damping components are connected between the outer end of the movable tube and the inner wall of the base box. A sliding plate is connected to the lower end of the movable tube, ball bearings are installed in the bottom plate of the base box, and a sealing plate is connected to the upper end of the movable tube. This highly stable shock-resistant table, through the horizontal buffer mechanism, effectively reduces the lateral kinetic energy transmitted from the ground to the table legs. Through the vertical spring damping components, it effectively reduces the vertical kinetic energy transmitted from the table legs to the tabletop. The combined effect of the horizontal buffer mechanism and the vertical spring damping components gives the table a high degree of stability, providing users with a more stable and comfortable experience.
