The Chicken can be placed on its wide surface or be turned upside down. When the chicken is placed on its back there is a rocking function. For the very small child who has just learned to get around the balance will be challenged by laying on the chicken and feel the rocking – and just by lying next to the chicken and touch it will provide a good and fun stimuli for the child. When the child can sit it will do it on the chicken – and later stand and walk on it. When used as a step stone the advantage is the fact that it does not slide. Another benefit is that the material is soft, which makes it nice to use even with bare feet. When the rocking function is used it is demanding for the balance – but just to stand on it will also place a demand on the musculature/stability of the foot. Subsequently the chicken has a very usable see saw function, since it lies very stable and secure, easy to control and has a good angle in relation to the stretch/movement of the ankle joint.
