This is a really good sturdy booster seat despite being a travel seat. I use it for when I have my nephew over once a week so he feels included at the dinner table but I like that you can vary the height of the seat as your child grows. In response to some of the reviews that the tray is quite tight, there are notches so you can adjust how close the tray is to your child's stomach, or not use it at all if they are sitting at the table. The seat was easy to put up and it fits very securely to the chair with one strap that goes around the back of the chair and one underneath the seat. Some other models only have the strap around the back and have a tendency to slide on the dining chair. Compared to some of the other non-travel booster seats I saw, this one does everything they do and is just as secure at a fraction of the price but with the added bonus of having clips to make it easily transportable and it folds quite flat too. I would recommend this.
