Description

technical field [0001] The invention relates to a desk and chair, in particular to a desk and chair for students' sitting posture correction. Background technique [0002] At present, students use desks and chairs for class, and the existing desks and chairs are generally matched. However, the existing desks and chairs are simple in structure and single in function, and cannot be adjusted according to the height of the students. The height and angle of the desk, and the height and angle of the chair cannot be adjusted, which can easily lead to incorrect sitting posture of the students, which will easily affect the students' body shape, and the students are prone to hunched over. [0003] Therefore, it is necessary to design a desk and chair for students' sitting posture correction that can not only adjust the height, but also adjust the angle, and can also correct the sitting posture of the students. SUMMARY OF THE INVENTION [0004] (1) Technical problems to be solved ...
