City Life 9mm Stair Runner Underlay The City Life 9mm underlay is a PU foam underlay tailored for stair runner use, combining comfort underfoot with long-term carpet protection. It’s 9mm thick and delivers excellent thermal insulation with a 3.04 tog rating, while also reducing impact noise by up to 47dB—ideal for quieter, warmer staircases. Pre-cut to 68.5cm widths and available in 5m, 6m, and 11m lengths, it removes the hassle of trimming down standard rolls. This underlay cushions each step, protects carpets from wear, and fits securely beneath runners in high-traffic areas. Designed for domestic use, it’s a practical, ready-to-fit choice that supports performance and comfort on every step.

Suitable for indoor use under stair runners. Trim to fit and check placement before installation. Spot clean with a damp cloth if needed.
