Yes. Underlay that is too soft or poorly matched to the carpet can allow excessive movement, which may affect how the carpet wears and feels. Carpet and underlay need to work together: the right choice depends on the carpet construction, room use and floor beneath it. A firm, stable feel is especially important in busy areas, while comfort and sound absorption may be priorities in bedrooms or upper-floor rooms. Thickness alone is not a reliable guide; density and the carpet maker’s requirements matter too. Before choosing, check that the proposed underlay is suitable for the carpet and the subfloor, and ask how it may affect the finished feel and performance. If you are replacing carpet, have the installer assess the existing floor and explain any preparation needed rather than assuming the old underlay can be reused. Bring the carpet details or a sample when comparing options, and confirm the recommendation for your room before ordering.
