Carpet curling is played on special carpets which can be rolled out quickly. Carpet curling is particularly popular with senior citizens associations which include keep-fit activities in their programmes, as well as in many schools. Nordifa delivered its first carpet curling carpet in 2000. The latest carpets have perfect glide, are wrinkle-free and have clear, durable markings. Bowls was introduced in Sweden in 2005, and is growing slowly but surely year-on-year. It is played indoors on specialist matting.
