How can you identify the quality of carpet?

Density is the thickness of the fibres and how tightly bound they are. The denser and heavier carpets will stand up better when walked upon or trodden on; thinner ones may give way in places without much pressure applied at all. To test this out for yourself: Bend your sample carpet backwards until you can see its backing clearly – if it has a clear exposé, then we’re talking low density (lower quality).
