The choice of material for an outdoor rug depends largely on the intended use of the rug. Rugs that expect to see a lot of traffic or that need to be moved frequently are usually made of synthetic materials. Natural fiber rugs are useful for adding texture.
Outdoor rugs in both natural and synthetic fabrics are durable and attractive. Natural fibers such as hemp, sisal and bamboo are long-lasting and sound-absorbent, though some are not comfortable underfoot. Synthetic rugs are often made of polypropylene or polyester. Polypropylene rugs often come from recycled materials. These rugs are easy to hose off or move around, making them useful near a pool or in a high-traffic area. Rugs made of synthetic materials are typically less expensive than those made of natural fibers.
