CAT is a light, stackable, resilient and versatile chair.

The chair features the same seat as on the earlier CINUS chair and the frame has many similarities with CINUS, so they are related like brother and sister.

CAT is extremely minimized, with only one short tube to hold the very thin back. A construction, which benefits the weight and strength as well as the resiliency and sitting-comfort. CAT might be one of the most elastic chairs, of its type, ever.


CAT is well suited for settings in rows, as the repetition of the back with its slits, as well as the circular mounting-flange, gives a significant and strong graphical effect. The rectangular shape of the seat with the five straight slits, visually binds the chairs together. The seat is, like the back, very thin and resilient and the slits prevent the body from sliding forwards.
