Sit, unfold, sleep - Hippo is a comfy futon chair that can easily be converted into a mattress. By releasing the back of the chair and lifting up the arms, Hippo lays out flat, becoming a thick, rich mattress that’s perfect for guests and sleepovers. Designed by Anders Backe, Anne-Sofie Voss, Ida Sofie Lange, Lars Wigh, and Troels Rask Pedersen for Karup Design.
