Innovating the existing bathtubs in the market, most of the existing products are mechanical combinations of bath tubs and bath beds, which are lacking in product experience and interest. This bathtub is to innovate the use of bath beds and bath tubs. The semi-sustained style is the main reason. This idea stems from the experience that almost everyone has had to play with swings when they are young. It is extremely joyful for the family to swing in the air. The design concept of this product is to pass this joyful mood and memory through the product， keeping it in everyone's mind.
