Anyone had any luck fixing this? My Son has problems doing what he's told, and despite repeated warnings not to kick it, or climb over the arm rest, he's managed to knock one of them off. Looks like a totally sealed unit so very difficult to get to.
ETA After nearly half an hour, armed with two pairs of tweezers and half a dozen chopsticks, I was ready to give up, when at last it clicked into place! I've no idea how, definitely luck more than anything. Such a cheap flimsy part to have where people can accidentally catch it with their feet.
