Wool yarn tufted into a backing, rolled out wall-to-wall. Soft, sound-absorbing, takes a footprint and recovers, dirties before it wears out. The premium floor covering for any interior that wants to be heard whispering. Lasts 15–25 years if loved; less if abused or wet.

Pile yarn (typically 80% wool, 20% nylon, or 100% wool) tufted into a primary backing (polypropylene woven scrim) and locked with secondary backing (latex, jute, or recycled-PET). Pile heights 4–14 mm; densities 1500–4000 g/m². Wool's natural crimp + lanolin gives soil-shedding and flame-retardancy without additive treatment. Dyes range from solution-dyed (colorfast) to skein-dyed (richer color, less colorfast).

visual
uniform pile from above; tone shifts under raking light; footprints read as a darker strip
tactile
soft, springy, warm — the most-talked-about sensorial signal in any interior
weight perception
heavy at roll scale, light underfoot
acoustic
swallows footsteps; a room with carpet sounds smaller than the same room with a hard floor
