The First Years Hot-Wheel Booster Seat features a deep contoured energy absorbing headrest that is adjustable to 8 positions, as well as having patented side impact head control that is tested to the strictest of Australian and International Standards! The 3-position shoulder belt guide helps parents with easy fitting and ensures your child will be safe, comfortable, and happy for much longer! From a comfort point of view, the seat excels with 2 cup holders, flip-up armrests (So no dangerous climbing over the top), deluxe stitched EZ Off-N-Wash padding and a nice and simple fold for easy transport and/or storage. To enhance your child's safety, it is recommended that they remain in a car seat until they reach a height of 148 cm and use a rearward-facing position until at least 15 months of age. This approach helps ensure your child is in a seat that is appropriate for their height and weight.
