The wood used comes from FSC®-certified plantations, managed correctly and responsibly, on the basis of rigorous environmental, social and economic standards. Its components interlock, so that each piece can be put together without using any metallic parts. The adhesives used are all formaldehyde-free and water-based. All of the finishes are natural wax. The only metal used is aluminum, an endlessly recyclable material. The textile fibres used for all of the upholstery are linen, wool and cotton.
