We hardly used a normal high chair. From the time our kids were big enough to sit in the booster high chairs, we were using those. These booster seats. They have straps, come with trays that can be used if you’re not at a table and the seat can scoot into the table like a normal chair. After being gifted one, a normal high chair seemed like an unnecessary large purchase.

These booster chairs can be used on the floor, in a chair at the table and can easily be tossed in the backseat or trunk and used in restaurants and at friends/family’s house while visiting. They are versatile and the tray works for play as well as eating.

Pros- small, portable, easy to take on trips or when eating out, work like a normal high chair as well as a booster seat, easy to clean, take up less space than a high chair and less expensive

Cons- Can’t think of any in all honesty. This is a product I felt was a necessity and one worked well through two kids. They did prove to be hard to sell in a yard sale, though.
You do need to be careful and make sure they are securely strapped onto the chair if your toddler moves a lot. They are also harder for the child to climb out of and if the straps are too loose, the chair can fall but the straps work similar to a car seat- as long as you tighten them in enough and strap it to the chair right, it’s safe.
