Rugs should always be anchored whether used on a hardwood floor or on top of carpet.
Do you put an area rug on carpet.
Better luck if it is a very short loop like an indoor outdoor carpet you are putting it on even a berber will give as you walk on in and make the upper rug buckle.
If there is a pile at all on the rug don t use.
While area rugs usually lay on wood floors you can also lay an area rug over carpet.
Don t put an area rug over a very long pile carpet such as a frieze or a newer soft carpet such as smartstrand because the area rug will not have firm support and will shift buckle and wrinkle.
Perhaps the biggest concern with laying an area rug over broadloom is that the area rug will have a tendency to move around on the carpet.
On a hard floor an untethered rug is more likely to slide or slip but when layering area rugs over carpet the rug is more likely to wrinkle or ripple.
When chosen correctly an area rug can enhance your carpeted space.
The extent to which it will move will depend on the style of carpet that is underneath the rug and the type of backing of the area rug.
If you never walk in the room or move furniture if it is just to look at as in magazine.
