Pile type: cut, loop or twist?
Cut pile carpets — where the fibres are trimmed — are soft underfoot and suit bedrooms and lounges. Berber and loop pile carpets are more durable and better suited to hallways and stairs. Twist pile, where fibres are twisted together, combines durability with comfort and is one of the most popular all-round choices in the UK.
Fibre: wool vs synthetic
Wool carpets are naturally durable, warm and resilient but cost significantly more than polypropylene or nylon. For high-traffic areas, a wool-blend (80% wool, 20% nylon) often offers the best balance. Pure polypropylene is affordable and stain-resistant, making it practical for family rooms.
Density and twist rating
A higher density rating means more fibre per square metre — the carpet will last longer and resist flattening. A twist rating above 4 is recommended for stairs and hallways. Always ask your fitter to show you the specification, not just the sample.
Underlay matters as much as the carpet
A good quality underlay extends carpet life significantly, improves comfort underfoot and adds thermal insulation. Do not let a fitter reuse heavily compressed old underlay — it will shorten the life of your new carpet.
