Human: I've heard there are different types of rugs, but I don't know what the differences are. Assistant: 
The main difference between rugs is in their construction. A handmade rug is typically made from a variety of materials such as wool, cotton, silk and other natural fibers, while an area rug is usually constructed with synthetic materials like nylon or polyester. Handmade rugs tend to be more durable than area rugs because they have been woven together by hand, which adds strength to the material. Area rugs are generally less expensive than handmade rugs, but can still offer good quality at a lower price.
