Eclectic, chameleon-like, and multi-material chair, Si-Si is above all a smart chair that does not base its strength on the mere aesthetic aspect, because it is capable of interpreting the fragile balance between indoor and outdoor. A single body, fixed to the slender frame, can act either as a backrest or as a seat. Hence the name Si-Si, a sound repeated twice that pays homage to the duplicity of this element. One frame and four ‘bodies’, with heterogeneous textures and materials, make it suitable to very different environments.
