I got the belt now. Delivery was quick and easy. I've seen it for the high chair (Hauck Alpha) provided and tested directly. It could be put on quickly and my son had fallen off. As lunge it will be useful. But when I tried to find a way how I can attach it to the chair, I was at a loss. I've tried a lot and eventually had no option except it zuzuknoten somehow. Perhaps it would be useful to send a guide with where you could see different types of attachment. Actually I think it's good, but I think there is room for improvement.
