Inspiration

Cassina Taliesin Chair by Frank Lloyd Wright

Originally designed in 1949, Cassina revived Frank Lloyd
Wright’s Taliesin chair just last fall. And for good
reason—its complex geometry and eye-pleasing angles have
long made it a pleasure to sit in. Not to mention its
construction, which is origami in the literal sense—each
is made from a single piece of plywood, and “folded” á la
the Japanese techniques of old.

Roric Tobin Designs Crane Chair

Roric Tobin’s chair, meanwhile, was inspired by a chance
encounter at a New York City boutique. “I was walking my dog,
and I saw this store that had a bunch of [cranes] hanging. I
was struck by how they they sort of looked like a chair,” the
designer tells Robb Report. “I came back to the office, and
my team and I got some origami paper and started making the
crane.” In light of the original’s success, the studio has
issued an outdoor version made of teak.

Sawaya & Moroni Mew Low Table
by Zaha Hadid Design

Late architect Zaha Hadid wasn’t known for
her curvaceous structures alone—a few of
her designs and that of her studio’s come to
a point, the Mew low table among them. The
piece’s converging surfaces and curves are a
more fluid origami than the above, perhaps,
and represent a Hadidian take on the beloved
Japanese craft.
