We use the seat as a second chair for our twins and a high chair are on the go. Since there are not two free highchairs in any place, the booster seat is really a good solution for us. While I would want him to inflate the restaurant not necessarily in front of everyone (is relatively heavy), but you can carry well inflated him. All chairs are probably not ideal for mounting, but so far we have not had major difficulties. The straps provide a flexible mounting. That the seat should be unstable, we can absolutely do not share. Our children are sitting quite like it and wriggle also strong rum. Of course, it looks sometimes from dangerous if they lean far to the side, but mainly the anxiety of parents is much higher than the risk that the child really can fall out sideways. Rather tilts the whole seat ... As with any chair I would not use it without supervision. How long does the product, I can still poorly assessed after 8 weeks. So far, there is no reason to complain! The seat unpack actually a significant plastic smell, which is, however, eliminated after a short airing. All in all, we can not say anything negative against this seat and certainly not in terms of the price. Since the price-performance ratio is very good indeed fulfilled! We would buy it again at any time!
