Musician Katarina Agnas and her husband from Stockholm had a little son who wouldn't sleep. The parents spent night after night lifting their son's bed and rocking him to sleep until their arms cramped.
Finally Katarina made a simple prototype. She fastened a spring to each leg of the bed and wrapped the springs in soft covering. Now she and her husband could easily rock their son's bed in all directions: sideways, up and down, and around.
