Lec

Auditorium chairs in set of three or four seats

Lec offers new possibilities for interior design in lecture halls. In addition to extremely clean and pure lines, design emphasizes designer’s desire for restriction of structural elements. The structure is based on stiff as well as strong and large plywood elements and a limited number of support legs. Lec is available in a set of three or four chairs. In addition to the visual lightness Lec’s ingenious structure offers architects more freedom in planning of e.g. air-conditioning. It facilitates the cleaning, too.
Lec adapts easily to different requirements and interiors, because the plywood structure allows a great variety of finish options. The seat tilts tightly against the backrest, which makes Lec a good option for narrow spaces. The strong plywood backrest allows fixing of writing tablet or cabling of electricity. For example, Lec is at home in educational applications.
