Benefits of Firmer underlays
These give added protection to the carpet against the hard sub-floor during normal walking. Indentations from furniture will be less severe where the carpet is fitted on a firm underlay. Firmer underlays will prevent excessive vertical movement and stretching of the carpet in use and will therefore help to prevent rucking problems
Examples of firmer underlays include Duralay Treadmore a high-quality crumb rubber underlay made by Interfloor.

Comments on Softer underlays
Soft, low density underlays do not give as much support in heavy wear areas as the carpet pile is effectively squashed against the sub-floor, accelerating wear and appearance changes. A softer product could eventually collapse under excessive pressure and allow the carpet backing to be distorted, preventing good recovery and making furniture indentations more severe. We would advise against using low density foam underlays of less than 8mm thickness as they are likely to reduce the life of your carpet and mean earlier replacement. back to top
