Danish “Slack I” Ivory Metal Floor Lamp by Mart van Schijndel for Martech, 1979
A 1979 “Slack I” floor lamp by Dutch architect Mart van Schijndel, produced in small numbers in his own workshop, Martech. Van Schijndel, an influential figure of Dutch Structuralism, approached lighting as architecture in miniature, a philosophy distilled in this tall, faceted silhouette.
Formed from planes of ivory-lacquered sheet metal, the lamp rises in a subtle twist, its surfaces shifting in tone as they catch the light. The concealed uplight at the top casts a soft glow upward while allowing a spill of illumination to wash down the open seams, emphasizing the structure’s geometry.
Handmade in limited quantities and standing just over six feet tall, the Slack I has become one of van Schijndel’s most sought-after designs, celebrated for its purity of form and the way it transforms light through its shifting planes.
