The shape of a play equipment is one of the main factors giving children the necessary stimulus for active play. By an attractive design, children become aware of the play offer. A friendly look creates a pleasant atmosphere and invites children to play. Fish Berta has an amiable appearance in the shape of a fish which provides a special attraction to the play area. The net and climbing grips, which stick like shells to one side of the structure, emphasize the look of a sea animal which can become the centre of a play area. Fish Berta offers play opportunities inside the structure and has a climbing net and a slide in the basis version. In addition, a central means of access through the fish body can be installed by a rope ladder in place of the small round table.
