Final answer:
Contemporary furniture is characterized by simplicity and functionality, with clean lines and modern materials. Kennedy can explain this style using Ludwig Mies van der Rohe's motto 'less is more'.
Step-by-step explanation:
Contemporary furniture, which Kennedy is using in her restaurant design, is characterized by the main feature of simplicity and functionality. This style often employs clean lines, minimal ornamentation, and the use of modern materials such as glass, stainless steel, and porcelain. The aim is to create a visually pared-down and highly functional space. For example, Ludwig Mies van der Rohe's motto 'less is more' perfectly captures the essence of contemporary furniture design.
