We use this booster since our child holds sitting alone (6-7 months). When closed it is very compact, so very easy to carry. We were able to install different types of chairs thanks to adjustable straps that attach under the seat and around the back. It effectively replaces the high chair at home and enables baby to be at the table with us, what pleases him greatly. The upholstered seat is comfortable, the five-point harness is really reassuring, especially with a small wriggling. It is easily cleaned with a sponge. In short, we're really happy with this purchase and would recommend it !!
