Technical Drawings: The document includes various technical drawings with reference numbers (e.g., REF. 644-4, REF. 644-2) and dimensions in both inches and centimeters. These drawings likely represent different components or configurations of a furniture piece.

Specifications: The furniture structure is made of wood and polyester-varnished tubular steel. The wood is covered with polyurethane foam of varying densities and polyester fiber. Seat cushions are made of polyurethane foam, covered with a protective case, and filled with white duck feathers, down, and polyester fiber. Back cushions have internal divisions and are filled with sterilized white duck feathers and down. The suspension system uses elastic grids, and the feet are made of steel, removable by screws. The cover is completely removable except for leather or similar upholstery. The frame, including arms and back, can be disassembled using screws.

Materials and Construction: The document provides details in multiple languages (German, French, Spanish) about the materials used, such as wood, iron, polyurethane foam, and polyester fiber. It emphasizes the modularity and removability of components, allowing for easy disassembly and maintenance.
