Cay Sofa – An Ergonomic Sofa by Alexander Rehn
Developed by Swiss designer Alexander Rehn, Cay Sofa is an ergonomic sofa that accommodates different positions of your body. You can sit on it for reading a good book, for playing games, for eating breakfast, for relax in front of the fireplace, for watching television, for listening to the favorite music and other fun activities. And one more thing that is very impressive from this sofa, no motors and no buttons attached, just simply a clever design.
Rehn should experiment with both form and size of the cushion and leg length underneath to design for any potential movement of the sofa. It is seen from his sketches.
