There are a range of pre-cut sections of luxury underlay available for all of the rugs we have in stock.
110 cm x 60cm
150cm x 90cm
180cm x 120cm
240cm x 70cm Runner
If laying a rug onto carpet you use the underlay Black side down, if laying the rug onto a hard floor you use the underlay grey side down.
The underlay is breathable and will therefore not oxidise flooring to allow discolouration.  The underlay gives a more cushioned luxurious feel to all of the rugs and creates a non slip finish.
