A seat body is assembled with a seat chassis device that has a seat chassis mounted on the seat body. The seat body has an accommodating space and guiding troughs each having a guiding opening. The accommodating space includes a propping portion to be resiliently flattened. The seat chassis device has a base connected thereto and is formed with sliding wedge portions to slide into the guiding troughs from the guiding openings. When the seat chassis slides to a predetermined position, the propping portion springs up and abuts against the seat chassis. A spring between the base and the seat chassis is upward pushed by a resilience-adjusting unit and has its upper end received in a dome raised from the seat chassis and received in a hollow portion of the seat body.
