Kartell Trays Trolley is a really cool design from the Italian designer Piero Lissoni. The shelves are made of solid, refined methacrylate and come in either glossy Black or White. The frame is made from chromed steel and comes on wheels. Great design that is perfect for any room in the house but especially the Office or Kitchen. Trays also comes in a Shelving System (no wheels) and Low Tables.
