Excerpt: The Chicco Oasys 2/3 is a high-backed booster seat for older children that literally will grow with your child. Not only is it adjustable height-wise, it also expands width-ways. It means your child is unlikely to outgrow this seat, and it fits all shapes and sizes inbetween.
Pros: Easy to install, adjustable height and width function, grows with child
Cons: Arm rests make strapping-in difficult, relatively heavy
