How to open the sofa?

1. Move two sets of sofas slightly, or move left and right, or move the connection position of two sets of sofas upward. After moving, a wide enough gap can be exposed, and then it can be put into operation.

2. When there is enough space between sofas, you can observe the position of the buckle, and the buckle point is divided into two parts, corresponding to the positions of the two sofas respectively. Observe the position of the buckle, reach in and pull up or down, and open the buckle with a little force, and the two groups of sofas can be separated smoothly.
