Berber (loop) carpet
A carpet construction in which the yarn is left as continuous uncut loops on the surface, producing a low, dense, snag-prone pile that is common in bedrooms, basements, and light-commercial spaces.
Also known as: loop-pile carpet, berber
Berber refers to a carpet construction — not a fiber type — in which the yarn is looped on the surface rather than cut. The loops are usually low and dense, which resists crushing and hides soil pattern well. Berber is often specified for bedrooms, basements, home offices, and light-commercial spaces where a low-profile surface is desirable. Fibers used can be olefin, nylon, wool, or blends, and the choice of fiber affects how the carpet cleans more than the construction itself does.
The cleaning tension with berber is snag risk. Because the yarn is a continuous loop, a snag can travel — a single pulled loop can cascade into a run across the surface. Aggressive brushing, hooking a wand corner on a loop, or dragging heavy equipment across the surface without care are the common causes. Professional hot-water extraction with a properly held wand and appropriate solution matched to the fiber type avoids the mechanical hazards.
Berber also has a distinctive relationship with dry time. The dense loop structure holds moisture close to the surface longer than a cut-pile carpet with the same square-foot moisture load, which is why extraction and airflow discipline matter more here than on cut pile. Adequate post-cleaning airmoving is what keeps berber from over-holding water into the backing or padding.
