The prince lionheart crib teether looked the perfect thing for our cot bed. Unfortunately you only get enough in one packet to go along one side, and not the full length. The kid (10 mths) is pretty good at getting fingers or teeth underneath and chucking them on the bed or floor or waving them around. We have found ourselves wondering at his talent for destruction or the rather lame product. We have since bought a long cot rail for the other side of the cot at a fifth of the price from the big blue swedish store which seems at least as good if not much better - time will tell on that one.
