[0008] Furthermore, each group of the limiting structures includes a telescopic rod, a spring and a convex block. One end of the telescopic rod is fixedly connected to the inner wall of the cavity, and the other end is fixedly connected to the convex block. The outer wall of the telescopic rod is wound with the spring. The convex block is adaptively connected to the limiting hole.

[0009] Furthermore, on the front side and the rear side of the bottom of the first sofa cushion, fixing shafts one are respectively penetrated. The two ends of the two fixing shafts one are respectively fixedly connected to the support plates.

[0010] Furthermore, a fixing shaft two is penetrated through the rear side inside the second sofa cushion. The two ends of the fixing shaft two are respectively adaptively connected to the sliding grooves, and the two ends of the fixing shaft two are respectively adaptively connected to the limiting grooves.

[0011] Furthermore, anti-slip pads are respectively fixedly connected to the bottoms of the first sofa cushion and the second sofa cushion. The two ends of the sofa pillow are respectively hinged to the second movable seats.
