The multifunctional step chair in the classroom is designed for better cleaning, saving space and checking whether the chair is suitable. Designers will go on field trips and sit in their own chairs.

Stair chair is a kind of public chair, which consists of four parts: chair seat, chair back, armrest and standing feet. Under normal circumstances, the standing feet and handrails are integrated to form a firmly installed handrail frame, which generally adopts steel-wood structure or steel-plastic structure and is widely used in lecture halls.
