This harness can only offer maximum protection when it is properly fitted and used. It should never be used in a bed or car, only in the high chair or when walking (rein included). First adjust the shoulder straps to size (A), followed by the chest strap (B). You can use the tabs (D) for adjusting the straps to size. The snap-lock (E) will be positioned on the child’s back, ensuring they can’t open this themselves. You can subsequently secure the side straps (C) to the high chair. Insert the ring (F) through the loop of the side strap. Make sure the side straps are effectively adjusted to size, making sure the child can’t stand up or swing. You can subsequently click the ring (F) into the hook (G) of the chest strap.
