Although this model allows height and chair adjustments and has a reclining seat, it offers less flexible features than comparably priced high chairs. Be wary of second-hand seats. Newer seats usually meet more stringent standards and have more features. Make sure the high chair has a wide, stable base and is sturdy. Also, check for sharp edges or caps that could be removed by a child.
Some experts also recommend purchasing optional shoulder straps, especially for active children.
Look for a tray that can be removed easily, preferably with one hand, but that secures tightly on both sides. The tray should also be lightweight, and move smoothly without rattling. Experts also prefer adjustable trays, so the infant doesn't have to reach too far for food. If the chair has wheels, make sure they have locking mechanisms, and try pushing down on the footrest to see if the chair can be tipped over. Some experts say wheels are convenient, while other believe they make the chair less stable, and can be dangerous if other children are around.
