Jeffrey Bernett Tulip designs in 2008. The internal frame is made of tubular steel and steel sections. There are two basic types: a stand in chromed steel wire or four-spoke polished cast aluminum, is supported above the frame. Different sizes for different uses: the waiting room, the room of a tree. The padding of the inner frame is flexible polyurethane foam while the seat cushion is in polyurethane foams, the lining is made of polyester fiber. Upholstery is available in leather fabric.
