Anji Mountain bamboo rugs are made of the finest quality bamboo in the world. The bamboo has been kiln-dried & carbonized to help prevent cracking and warping. These are ecologically friendly rugs featuring unique styles and sizes both modern and traditional. Our rugs brilliantly complement all types of flooring including carpet, hardwood, marble, and tile. For added value, each rug is manufactured with a ventilated, non-slip rug pad backing that provides extra coushioning and extends the life of the rug. Our bamboo rugs are suitable for all indoor uses, as well as for limited outdoor use in covered and screened porches, lanais, gazebos, etc. Border Widths: 2'x3'=6cm 4'x6'=8cm 5'x8'=12cm 7'x10'=12cm 7' Round=8cm
