The reinforcing rib 210 can improve the strength and rigidity of the support leg 180, thereby significantly improving the bending rigidity of the support leg 180, ensuring that the chair leg maintains good mechanical properties during long-term use.

[0040] The reinforcing rib 210 is in a rhombus shape. The rhombus-shaped reinforcing rib 210 is not only beautiful, but also can disperse the force, further enhancing the overall rigidity of the supporting leg 180. The base 230 and the mounting portion 240 are integrally formed. The integrally formed base 230 and the mounting portion 240 have a simpler and more beautiful appearance, reduce the steps of installation, and improve the structural stability of the center seat unit 100.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
