Redwood is a natural wood. Redwood trees grow to unbelievable size. In California they have the great redwood forest where cars can actually drive through cut outs on some trees. There is also some fake redwood made from plastics or paper products but they don't have the clean smell or feel of natural redwood.
It is natural but there are man-made imitations.
It can be made from natural or man made fibres.
