Do you put an area rug on carpet.
Although placing rugs on carpeted areas is generally considered a design faux pas there are many reasons to put an area rug over your carpet and many ways to do this in a pleasing stylish way.
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.
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.
Rugs should always be anchored whether used on a hardwood floor or on top of 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.
As i stated above it never really works.
