A soft washable rug with an extraordinarily comfortable pile, this rug's lightness and foldability makes washing easy. Shell is a solid-color rug with geometric line drawings in relief, like ancient ammonite fossils. Its tone-on-tone effect is inspired by the accidental designs of beach tides— imprints left by waves on sand. Recycled polyester is transformed through heat into a soft, sustainable fiber with the look and feel of wool. It's also highly durable, OEKO-TEX certified for safety, mildew-resistant and machine-washable.
