This dynamic air cushion (also known as a wobble cushion) can be placed in almost any chair and ensures an active sitting position. This is not only good for children, but also for adults. Placed on the floor, your child can sit, stand, kneel, lie down or swing on it, it trains the sense of balance and muscles in many ways.
There are studs on the top, this stimulates the wobbling even more. The hardness of this cushion can be adjusted with a straw.
