Remember, a twisted harness strap will be much more likely to injure a child in a crash than a broad, flat strap. The wide straps are intended to be flat against the child s body to distribute the forces of the crash over a wide surface area. Straps should not be ironed.
Consumers can order new straps from the manufacturer if they get too filthy or twisted.
