Food, housing, transportation, etc. will have different needs. For the appliances and utensils used, different types of forms will be produced due to differences in body shape. Tables and chairs that are often used in daily life are high on the human body. Dwarf is different, resulting in greater use restrictions, especially in the use of the table, the general table is a fixed length, width, height and certain specifications, although it can be applied to people of general size, for higher or slightly Short people, when using the table, will be somewhat uncomfortable. Although there are height-adjustable chairs in the room, the height can be adjusted to match the height of the table. However, the height-adjustable chair can be adjusted to a limited height. Due to the use of tables of various heights, especially children and adolescents in the growth stage, the growth rate is quite fast, so the tables and chairs used will be different. Inch of demand, however at present people use tables and chairs, no special requirements for height tables and chairs, but the chairs are condescend to both feet Inch applications, for those with large differences in body size, create a lot of inconvenience when using tables and chairs.

People use tables and chairs for a long time in daily life, such as eating, handling paperwork, using computers, reading books, listening to music, or working in the office. They must use tables and chairs to perform various related tasks, and use tables and chairs. It is also long. If the height of the table and chair does not match the user's body shape and is not suitable, it will cause the user to feel discomfort or soreness after using the table and chair for a long time. The size of the table and chair is directly related to the user's body shape. Relationship, but different users have different body sizes, but the size of the tables and chairs is fixed, and it is not possible to change the size of the table and chair with different users. The table is placed near the table because of the various items. The height of the table is not suitable for the user's body shape, which may cause the user's body or limb to assume an improper posture. For children or teenagers who are in the growth stage, as the body grows and the body shape changes, the height of the table is also used. It will need to be adjusted to meet the needs of different height tables after changing body size, so the use of the table is more direct for the human body. Relations, various types of tables available in the market are mostly fixed size can not change, less ergonomic, in practice, there are still many missing and inconvenience, to be improved.
