The unique shape of the Grillage outdoor chair from Ligne Roset comes from its unorthodox production method: a sheet of perforated metal is stretched to create a mesh, then folded origami-style into the final product. The wire mesh provides both comfort and ergonomics in an all-metal piece of furniture, but it may also be dressed with a special quilted covering for added comfort and a warmer look. Dining chairs and a sofa are also available.
