Sho, a multifunctional mattress, was designed by Biwei Pan, a student at ESAD de REIMS in France. His simple system transforms from a flat bed to a sofa and a chair with the help of a metal support rest. The lightweight latex mattress is readily adjusted and cleaned, simplifying the task of furnishing a small space. Encased in what looks like linen, the prototype has a casual, even rustic quality to match its ease of use.
