Man-made fibres have come on in leaps and bounds over the last few years. They no longer suffer with static problems and in most cases completely stain resistant. Polypropylene is most popular fibre used by manufacturers. This is so stain resilient bleach can be used to remove stubborn stains without harm the carpet.
However the one thing a man-made fibre carpet doesn’t have that a wool carpet has to offer is a natural pile retention. Wool carpets are renowned for keeping their appearance longer as time passes. Their natural oils shed dirt and will spring back quicker under pressure.
Which ever you choose will depend on your budget. Providing the carpet is suitable for the area you are wishing lay it there is no reason why it shouldn’t give you good service.
