Abstract

The invention relates to a double-seat desk and chair with steel angle frames used by students in various schools. Frames of a desk and a chair are welded by using steel/iron angle materials; and a face plate, a base plate and a lateral plate are fixed on the frames by using bolts. Wood frames are replaced by the steel/iron angle frames, so that the desk and the chair are firm and durable and the legs and the frames are not broken. The desk and the chair can be recycled and are beneficial to the protection of forest resources. The height of the desk and the chair can be flexibly regulated, so that the needs of different student body types are satisfied. Besides a laying box on the desk, a very large space is further remained under the chair and used for putting books or other articles of the students so as to ease the problem that the students have no place for putting books because of too small laying box of the existing single-student single-seat desk. Various bad postures of the students are effectively limited by the double-student double-seat chair, so that the health of students is protected.
