Just taken delivery of our brand new stage 1 car seat and I'm a bit concerned about the packaging. We bought a Kiddy Infinity pro because we wanted the safest car seat we could buy but it's come ready assembled in one large box in a plastic bag with 3 long thin strips and 2 little bits of polystyrene for protection- they're not molded or anything, they're just strips. The torso protection shield had come loose and the bottom of the box had come undone - it was held shut by a strip of sellotape - and it's been rattling about in a Parcel Force van, so I'm worried any knocks it will have received in transit will have rendered it useless, in the same way that a crash helmet would be unsafe after being dropped. Should I send this back or am I worrying over nothing?
