THE Green Brigade has cried itself hoarse, but from the look of it they have managed to gain very few converts to the concept of using alternative material for contemporary furniture. There's nothing like well-seasoned wood to add that touch of class to interiors, though people today are trying to minimise its use with a combination of glass and wrought iron. Teak and cedar remain all-time favourites but the heavy ornate look is out, slim-and-smart is in.
