For your consideration I submit a floor lamp called Stacking Lamp designed by Canadian designer William McDonald. Inspired by the classic stacking ring children’s toy, Stacking Lamp is versatile, customizable and colorful.

Stacking Lamp can be customized by choosing any combination of 4 components to stack over the wooden dowel- lampshade, coat hanger, or spacer. Rearrange the components to conform to your space. The shades can be stacked facing down for reading/ task lighting or up for ambient lighting. Hooks are useful for bags, sweaters, scarves, etc. The components are steel constructed, and are available in the colours shown.
Stacking Lamp was shown at the 2013 Interior Design Show in Toronto.
