We went to independent carpet company and spent over 6k on carpets and flooring we specifically asked for a hard wearing stair carpet due to living in townhouse. Runner carpet chosen after recommended by sakes person and paid additional for carpet banded. It was fitted 4 weeks ago but already signs of sections unraveling and loose threads. We do not wear shoes and only used hose hoover. Carpet is a wool and tencal mix 6 mm. we check manufacturers website where carpet states only suitable for bedrooms and living room with medium use. We have contacted carpet shop and asked them to come out to look any other advice.
