The 'Cay Sofa' addresses one's needs after an exhausting day, to return home to relax in front of the fireplace, television or to just enjoy a good book. Developed by Swiss designer Alexander Rehn, 'Cay' can be considered a landscape for your living room, able to react to your various needs. The user becomes the protagonist, and through his or her movement and interaction with the furniture object, alters its shape and sitting angles to accommodate their body accordingly.
