What is a trampoline like?

Treadmill, also called eight-step bed, is the largest bed in traditional furniture in China. Produced in the late Ming Dynasty. It can be roughly divided into two types: one is a column stepper, which is an early form of stepper, and the other is a column stepper, which is a typical stepper. Pedal bed is divided into "big bed" and "cool bed" in Luban Jingjiang's family, which is actually a simple and complicated form of pedal bed. Pedal bed was a popular big bed in Ming and Qing Dynasties. The trampoline is unique in that a "cabin" is added outside the crib. From the appearance, the crib seems to be placed on a closed wooden platform (this platform is from Beijing or called "Horizon"). The platform protrudes two or three feet from the front of the bed. Wooden fences are set at the four corners of the platform, and some even have windows on both sides, thus forming a cloister in front of the bed. Although it is small, people can enter, and stepping into the cloister is like stepping into a room. This kind of bed is very big and has a relatively independent range of activities in front. Although it is used indoors, it is like a small independent house. Pedal beds are mostly used in the south. Because the south is warm, there are many mosquitoes and flies. The function of bedstead is to hang mosquito nets. Furniture models unearthed from Panshi Tomb in Shanghai, Liao Tomb in Fucheng, Hebei, and Tiger Hill Tomb in Suzhou all belong to this category. In the north, it's different. Because of the cold weather, people usually sleep on the warm kang, that is, they use beds. In order to make the room spacious and bright, it is only necessary to install low bed enclosures at the left, right and front. The environmental space caused by the overall layout of this bed type is like a small house in a room. There is a terrace and a door railing under the ladder bed, which means "bed in bed, cover in cover".
