What is Chair Cane? Chair Cane is the outside bark of rattan, a jungle vine of Borneo, Sumatra and Malaysia. It grows in dense forests and frequently reaches tree height causing it to fall over and form a matted undergrowth. The stem, which is covered with beautiful green foliage grows in length from 100 to 300 feet and is seldom more than one inch in diameter. For export, these stems are cut in 10 to 20 foot lengths. The outer bark is stripped from the main stem leaving the inside core which is generally called reed. The outside bark is cut by machine into various widths and thickness for usage as cane seating material or for wrapping and binding other materials together.
