Some students have different sizes of bunk bed. Generally, the size of the bottom floor is large, about 1200mm wide and 450mm high, and the second floor is about 1000mm wide and 1400mm high.

Students' dormitories also have bunk beds with iron frames, and the specifications are generally around 2000 * 900 *1700 mm. The columns of bunk beds are made of high-quality steel pipes with 38*38 square pipes, and the iron beds are welded with carbon dioxide, and the surfaces are rustproof, phosphatized, antistatic and dedusting, and cured at high temperature.

Students go to bunk beds, including bunk beds before and after school. The best size before school is 160cm*90cm*35cm, and after school is 180cm* 120cm*40cm.

If they reach school age, students should get on and off the bed according to the standard of adult bed. The length of the bed is generally 190cm, and the widths are 80cm, 90cm and 100cm. The height of the bed is about 40-44cm, which is slightly lower than that of an adult bed.
