The LUC chair is stackable and plays with the theme of a band, which takes up the substructure and is optically closed to the backrest. This theme can be found in the base again. The base is being considered as one 16mm steel tube. Seat and backrest are made of bent 2mm aluminum and are connected to each other at their lowest point. There both parts are fixed “invisible” like a “sandwich”. So it appears as if the seat is “hanging” and that seat and backrest are made out of one piece. For the comfort seat and backrest are upholstered with deep-drawn PET-felt in different colors. Further information on Bottcher+Henssler is available here.
