The seat, or Nest, is supported by an ash wood base, the result of meticulous carpentry. Like tree branches, the upper part of the legs embraces and surrounds the seat. The ash is available in a wide range of stains, from very natural tones to more artificial ones like green or orange. The fabric covering the seat is available in two versions (with a zipper or with piping). The version with a perimeter zipper is softer and allows the inner part of the seat to be removed. The version with piping is completely fixed and has a tighter upholstery. The outer part of the seat is faceted to accentuate all its lines. In contrast, the inner part is much softer, plusher, and more inviting.
