Description

Technical Field

[0001] The utility model relates to the technical field of integrated desks and chairs, in particular to an integrated desk and chair for preventing students from myopia. Background Art

[0002] Tables and chairs are one of the commonly used furniture in people's life and study. Most of the existing tables and chairs adopt a split structure design, that is, the table is a table, and the chair is a chair. In some specific occasions, such as education and training, due to the small room, in order to place more tables and chairs, an integrated table and chair is designed, that is, the table and chair are integrated together. This type of structure generally extends in front of the seat with a vertical pole, and the top of the vertical pole is set on the table top. Through this integrated combination, the purpose of reducing the floor space is achieved;

[0003] Some existing desks and chairs cannot adjust the sitting posture of students. Since students have poor self-control, they are prone to lying on the table to write. The distance between students' bodies and desks is too close, which can easily cause hunchbacks and myopia. Therefore, an integrated desk and chair for preventing students from myopia is proposed.
