This plush, modern sofa by Zaven for Zanotta (hence its quirky name, Za:Za) was designed as a monobloc — that is, it’s polyurethane foam is one single piece — and with the intention of creating “a tender, embracing expression.” Polyester straps adhere the seat, back and armrest (made of regenerated polyurethane and regenerable polyester balls) to the steel frame, which comes in matte black or red.
