Thanks to its modular structure, Çelebi can be used on floor surfaces with or without platforms. Its beginning, middle, and end modules help form a seat for the intended number of people. Its comfortable backrest and seat are made using polypropylene to resist the harms of extensive use. When not in use, the chair’s seat base automatically closes, providing a larger space for movement.
