Focal Point. Use an area rug to create a focal point in your room. A family room rec room games room or living room are all excellent candidates for a focal point area rug. If you have a games room a rectangular rug beneath the pool table looks awesome. If you have a fireplace an area rug in front of the fireplace adds elegance and luxury and it's a comfy place to sit and enjoy the fire. Now an area rug has another benefit. It will save wear and tear on your carpet especially if you place it in the high traffic areas. Choose something that stands out from your room decor or blends in. Your choice let your creative juices flow.
There are other kinds of small carpets like rag braided sisal chenille and shag made of various kinds of materials like cotton silk leather wool and synthetic fibers. You can get area carpets for children with games and bright children's designs on them. You can get bath mats that are washable.
Remember to bear in mind what part of the room the rug is going to be positioned; whether it is placed on doorways or near air vents etc. This is because some rugs are too thick or some doors just don't have enough space allotted for an area rug; this would either cause the door to not open or allow the rug to slide and shift every time the door opens. Also there are rugs that can't withstand the heat from air vents. Make sure you pick a rug's material carefully based on the placement of the rug.
