We're about to move into a new house and need to re-carpet. Now my mum always said wool is the best fibre as it cleans and wears well. But in Carpetright the guy rubbished that theory and suggested polypropylene. I just don't believe him - surely natural fibres are best? So can anyone help me out with advice/personal experiences? We need to carpet the kids rooms, the hallway and stairs and the playroom (converted cellar).
