Question Chicco Keyfit moving inside base?


New member
I just installed my Chicco Keyfit 30 base in my '04 TSX in the passenger side using LATCH. It's completely snug and level. It barely budges at all when I try to move the base where it latches.

However when I put the car seat in, the seat moves side to side inside the base. It's moving less than an inch, but it still seems insecure to me. Is this normal, or do I have a bum seat (or base)?

Secondly, we are having a bit of a debate about whether it's still necessary to get the seat installation inspected if the base is completely solid and level - my vote is yes. I'd be interested in other opinions!

That sounds strange to me... do you have a second base you can try? Or can you go to BRU and try their floor model with your carrier and see if it feels the same?

Or, call Chicco - the couple times I've called them they've been very knowledgeable and helpful over the phone.

And, it's always a good idea to have a technician go through a check with you - just in case you missed anything. :)

A little movement (measured in millimeters or maybe centimeters) is ok. There's a little wiggle room in there. But it shouldn't be massively rocking, or nearly coming out, or even feeling like it might come out. I agree with calling Chicco and asking them if you're not certain.

When I do a check with a parent I do far more than reach in and wiggle the seat. It takes about an hour. I go over the seat -- front, back, sides, handle, base. I go over how to harness and when it's tight enough. When the seat is outgrown. Then for an infant seat I show a LATCH installation, seatbelt installation, and baseless install. For your carseat, the primary errors I see are using LATCH in a non approved position, and then putting the bubble in the middle of the lines, rather than to the more reclined side. Chicco is not clear on that in their manual in the least. But the line closer to the child's feet is the 45 degree angle for a newborn, and the line closer to the front seat is the 40 degree line for an older child.

Your seat is easy enough that if you have it installed properly (feel free to post pictures and we can double check it) that you're probably good. Your seat is one of two where parents will routinely say, "That's it?" after we're done. :)

Thank you so much for the responses. I tried our second base and the seat moved just as much. It doesn't seem in danger of coming out of the base, it's just more wiggly, when I thought it would be basically unmoveable once the seat was in the base.

I think I will take it to be inspected just to be on the safe side. Thank you!


Im having the same concerns with my chicco key fit 35. I tried both bases and they are both more wiggly than im comfortable with, the base itself is secure, level and moves very minimally on its own but with the seat clicked in there is quite a bit of play between the base and the seat, the seat does not release from the base so im sure its clicked in properly. Curious about what your ultimate fix was.
