Make your entryway more resilient from the ravages of weather by using coir welcome mats. Coir is a natural fiber that comes from the outer husk of a coconut. It is biodegradable, compostable and resistant to both mold and mildew, which makes it the perfect material for outside door mats. The mats made from this fiber are highly sustainable and rugged. They are also eco-friendly and don’t pose any allergic reaction like synthetic mats often do. Garden Products Galore has several coir doormats to choose from. There are lovey patterned ones and also ones with sayings to welcome guests to your home.
