About Anji Mountain Bamboo Rug Co. 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. The dense, durable bamboo that Anji Mountain Bamboo Rug Co. uses is carbonized and kiln dried to remove moisture, which helps prevent cracking and warping. Because of this process, their bamboo rugs and office chair mats are ready to withstand the dry heat of your home or office in the wintertime or the arid climate of those living in the desert and mountains. * Made of durable moso bamboo * Machine-planed and sanded for smooth finish * Mitered polypropylene borders and clean design * Made in China * Measures 9L x 6W ft.
