"This trapeze was made by my teacher at circus school," says Sophie Demenge founder of Infant brand Oeuf. "I was living in San Francisco in a big Victorian house with roommates. The ceilings were so high I could hang the trapeze and practice at home. Now my kids are taking over—it's the first thing they do when they get up and the last before going to bed." The rug is an old kilim from Turkey; the Eames Lounge chair is from Demenge's childhood living room Paris—"A testament to the great quality of this 30-something-year-old chair," she says. The couch is from Room & Board.
