An Lena is an attempt to challenge a basic principle of chair design, utilizing a wall and rubber friction grips to provide another form of support augmented by weight and gravity of someone sitting.
It uses the wall as a clutch for the backside to rest against. Simone Harbert designed this to try to create more public community spaces for less cost. Having a place to sit is inviting to the public and encourages lingering which leads to a gathering spot for a community.
This peculiar chair, called the An Lena chair, was created by Simone Harbert as part of a student exhibition at the Burg Giebichenstein College of Art and Design in Germany.
