With a handwoven structure, Pebble Rug contrasts the materials of its soft, woolen loops with its sturdy canvas base in a cooling jute yarn.  Material: Pebble Rug is made from 60% wool and 40% jute fibers, both natural materials that are easy to clean and preserve. The rug comes with a canvas backing pasted with synthetic latex which ensures that the rug lays smoothly on the floor.
