Never hot or cold, sticky or 'icky', the MouseRug's surface is made of millions of individual soft nylon microfibers with air space between to provide the most beautiful and comfortable mousing surface on the planet. 25.5cm x 18cm. This splendid Qashqa'i shekarlu rug covers the most famous piece of furniture in the world, Sigmund Freud's psychoanalytic couch. The brilliantly coloured rug was made by one of the nomadic tribes of the Qashqa'i confederacy in Persia in the nineteenth century. Freud's patients reclined on this rug recounting their memories, dreams and fantasies.
