Anji Mountain Bamboo rugs and office chair mats are ecologically friendly. Bamboo has a robust root system that generates multiple new shoots for every mature stalk that is harvested. Unlike hardwood that can take decades to grow to a mature height ready for harvest, bamboo grows 8-12 feet a year! When you purchase a rug or office mat from Anji Mountain Bamboo Rug Co., you help support the ecologically responsible practice of regulating sustainable bamboo forests instead of clear-cutting old-growth hardwood forests.
