Which American pop artist is known for large-scale soft sculptures of everyday objects?

The American Pop artist known for large-scale soft sculptures of everyday objects is Claes Oldenburg.

Oldenburg transformed ordinary things—food, clothing, household tools and consumer goods—into oversized, often humorous sculptures. His soft versions used materials such as fabric, canvas, stuffing and foam, giving familiar objects an unexpected sense of sagging, weight and physical vulnerability.

He began experimenting with soft sculpture in the late 1950s and became associated with New York’s emerging Pop Art scene in the 1960s. His 1961 installation “The Store,” staged on Manhattan’s Lower East Side, presented handmade sculptures resembling shop merchandise. The project challenged the distinction between fine art and mass-produced consumer culture.

Oldenburg also became famous for monumental public sculptures, including “Lipstick (Ascending) on Caterpillar Tracks,” “Clothespin” and “Spoonbridge and Cherry,” the latter created with Coosje van Bruggen. A frequent mix-up is identifying him mainly as a painter like Andy Warhol or Roy Lichtenstein; Oldenburg’s defining medium was sculpture, especially playful enlargements and soft transformations of the everyday.
