The supporting frame has a main body and four side bodies fixedly mounted on two front ends and two rear ends of the main body. The supporting members are mounted on bottom surfaces of the seat cushions and are connected to the supporting frame. Each one of the supporting members has multiple supporting elements respectively located at a front half section and a rear half section of a corresponding one of the seat cushions.
