I was looking at these and came across the below recall information so just thought I would put it here as a bit of info. I don't know if this applies to Australian stock, but it is always interesting to be aware of these things...

"Description: This recall involves the 3-in-1 High Chair to Booster™, which converts from a high chair to a toddler booster seat. It includes a removable tray, height adjustment and folds for storage. The product number (P5369) is printed on the side of the seat, on a label on the seat pad, and on the product’s packaging.

Hazard: The seat can fall backwards from high chair frame if the booster seat release is unlatched while the child is in the product. Also, the seat back can detach if not fully snapped in place, posing a fall hazard and risk of serious injury to young children.

Incidents/Injuries: The firm has received one report of a seat back detaching and child falling out, resulting in a skull fracture."
