Employing traditional methods, their craftsmen individually hand build each frame using timber from renewable sources. The frame is carefully constructed, using hardwood with joints glued, screwed and dowelled together for maximum strength. Tetrad use coil seat springs for greater durability ensuring our furniture will stand the test of time. Working closely with their suppliers, Tetrad buy the latest selection of materials, components, hides and fabrics from around the world all of which are subjected to rigorous testing, to ensure they remain at their best for many years. Tetrad are extremely proud of their British, high quality and stylish products – and we hope that you also will feel the same about our Harris Tweed sofas and chairs, when they are in your home.
