The Suru Diari chair is made from Weidmann hardboard (like Masonite), produced with only unbleached wood fibre and water. No adhesive is required - the lignin in the wood binds the cellulose fibres - which means the material has no added formaldehyde (NAF), is plastic-free and is completely biodegradable. This is the raw appearance. For the coloured versions of this product, Suru use a biodegradable milk-based paint, ensuring the product is safe to use and retains its biodegradability.

Huntonit textured ceiling and wall panels, produced in 900 kg/m3 fibreboard (hardboard) using the wet method. The surface has a wood grain effect texture embossed during production.
