When recommending an area rug, my preference is towards 100% wool, especially for families with children. Here are the reasons why:
Wool resists dirt, retains its appearance and stays cleaner longer. Its natural lanolin helps to repel grime. Its ability to absorb moisture prevents a build-up of static electricity, which means that wool does not attract dust from the air.
Wool is water repellent. The scales on the outside of the fibre cause liquid to roll of the surface, thereby repelling the liquid.
Wool is naturally elastic. Wool can be twisted and stretched and then return to its natural shape. That's why wool carpets retain their springy pile for many years.
Wool insulates against noise. It absorbs sound and reduces noise level considerably.
A high-quality wool rug should last a lifetime so cost should be considered as a long term investment, much like well made furniture. In a future blog, I'll explain how to recognize a high-quality rug.
