During the assembly process of the cabinet, because the height of the cabinet is high, a high and low work bench is often needed to assist the work.

At present, the work stools on the market are mainly climbing stools with fixed heights. There are 2-3 stool surfaces, and the appropriate stool surface is selected according to the working height. Because the height of the stool surface cannot be adjusted, the application range of the climbing stool is relatively small. In addition, because the size of the high and low work bench is often large, it has a large mass in most cases, so it is inconvenient to move.

In order to solve the above problems, we have developed a draggable high and low work bench.
