I bought this as a room divider for my infant son. He is 10 months old and 10kg. When he stands and pulls at the gate with his whole weight, the gate does not topple over. It does move from its original position on the floor but it is not an issue for us. We are mainly concerned about it falling on him but it would only be the case if he climbs on top of it which is not possible (yet!). Very happy with this product!
