The appearance of the learning furniture is displayed directly in front of the user. It is a visual representation of function and structure. The appearance of a flower depends on its structure, especially its external structure. However, there is no correspondence between appearance and structure, and different appearance forms can be represented by the same structure. There is a larger form of appearance.

The combination of degrees of freedom and space is quite selective, such as the basic structure of the dresser is the same, but its appearance form is different.

The emergence of the external expression function of the furniture form, but also the cognitive function, can also play its aesthetic function, thereby producing a certain mood atmosphere, forming a certain artistic effect, giving people the enjoyment of beauty.

Materials are the material basis of furniture. In the history of furniture development, it can reflect the level of productivity development from furniture materials. In addition to wood, metal and plastic, there are rattan, bamboo, glass, rubber, fabric, decorative panels, leather, sponge, etc. However, no material can be applied to furniture production, and the application of furniture materials is also selective.

Any furniture is designed for a certain function. Therefore, the function of furniture constitutes the central link of furniture, is the precursor of furniture development, and is the driving force to promote the development of furniture. In furniture design, the design object should be analyzed from the perspective of function, so as to determine the structure and appearance of the material. Generally speaking, the functions of furniture products can be divided into four aspects, namely technical functions, economic functions, use functions and aesthetic functions.

Including the internal structure and external structure of furniture, internal structure refers to a certain combination of furniture components, which depends on changes in materials and the development of science and technology. Such as teaching furniture, plastic furniture, rattan furniture, wood furniture, etc., have their own structural characteristics.

The external structure of the furniture is in direct contact with the user, which directly reflects the appearance of the furniture shape, so it must be adapted to the user in scale, proportion and shape. For example, the height of the chair, the depth and angle of the backrest reduce fatigue, while storing furniture makes it easier for users to access items to accommodate the size of the items. The external structure, designed according to this requirement, lays the foundation for the aesthetic requirements of the furniture.

The constituent elements of teaching furniture include four elements: material, structure, appearance, form and function. Among them, function is the lead, the driving force of furniture development is the structure, the structure is the basis of the function, is the basis for the realization of the function. These four factors are interrelated and mutually restrictive. Since furniture is designed and manufactured to meet people's material needs and purposes, furniture also has the function and appearance of formal elements.
