We had our new Chicco Keyfit 30 installed yesterday at the fire dept. They used the latch system and the base is really secure but when we put the seat in the base the seat is loose. Is this normal, I mean its not like I can pull it out but I can wiggle the seat around inside the base but the base is still stable. We purchased it at BRU and I can take it back but we live about 2 hours away and I don't want to deal with the hassel if the next one will be the same way. TIA!
