Rated 5 out of 5 by from Fantastic product This underlay was suggested by a lady in the Bishop Auckland branch as the item I wanted was not in stock. It is so light, strong and easy to handle when laying it. Thanks to the young lady for getting me to buy a superb product which is highly recommended.
