'Roll up service carts mean you never have to leave bed' Zittel has said. Her carts are equipped for dining, office work or personal grooming - one is left empty for the owner to customise. The work relates to earlier modernist artist groups like the Bauhaus, which applied the principles of design to every material aspect of life. Yet Zittel's vision is not utopian: 'A-Z is not an ideology, nor is it a strategy. It is a mission to learn about our values, our needs, and how we choose the roles we play'.
