Sliding seesaw is the one which can be played by single. Sliding seesaw has a U-shaped track carrying a few sliders with certain weight. These sliders can be moved optionally to balance each side. The sliders and the U-shaped track are magnetic in order to fix the position. In this way, it can realize a child single playing and parents playing with their children. In addition, cartoonish icons on the outer surface of the Sliding seesaw show the growth of a tree marking the growing process of children interestingly and feeling their growth visually.
