“Though you may not realise it, you’ve had a waterbed too,” Lars Brunsø points out, “we all have – our mothers’ wombs. There’s no better or more natural way of sleeping.” People across the world agree. Lars Brunsø began working with waterbeds at his student dorm back in 1981; today, he is the founder and director of Akva Waterbeds, which annually distributes 10,000 specialised waterbeds to over thirty countries from their own expert factory in Ry, near Århus in Denmark. These special beds have even proven helpful for people with back pain.
