There are several pros and cons of multi-level loop carpet. Each style of carpet has positive and negative attributes, and those pros and cons can differ depending on your particular use situation. For example, a Berber style carpet is often less visually appealing than a multi-level loop carpet, but it is very durable. This may make it an excellent choice for an office building but less appealing for a family room.  
 
Multi-level loop carpet is made by running rows of cut pile and loop pile. The loop piles are in differing heights, creating a multi-dimensional look. The style used to create the cut and loops can be random or create a pattern.  

Pros:
 
The pros and cons of multi-level loop carpet make it easy to decide if it is the best installation for your space. The multi-level loops create a distinct appearance, making it easy to blend rooms. The carpet itself is dense, so any spills will typically remain on the surface, which makes quick and easy work of cleanup.  

Cons:
 
Of course, no choice is perfect. Multi-level loop carpet can wear under the stress of high traffic, so it may not be the best choice for hallways and stairs.  
 
There are other factors to consider when selecting carpets. You should also ask about the face weight, which is the amount of yarn in any square yard of the carpet. The higher the face weight, the thicker the carpet. Thicker carpets feel more luxurious underfoot and often wear better. The carpet twist indicates the number of times the yard is twisted per square inch, with a higher number indicating a more durable carpet.
