Cosi 10mm Underlay

This polyurethane foam underlay is suitable for all areas of the home and gives a softer more luxurious feel to most carpets.

Made from recycled foam this underlay is both very comfortable and light in weight.

This underlay is an excellent insulator with a very high tog rating compared to most other underlays.

It can be used all around the home, however, we recommend a thinner, firmer underlay such as Cosi 8mm or Cloud 9 Contract 8mm for stairs.
