Unable to cleanI bought this car seat about 9 months ago. Pros: It is very sturdy and easy to buckle in the car. It’s well cushioned too.
Cons: it’s very heavy but I believe all car seats are. The material at the back of her head causes her hair to become matted up(which could be due to her hair type). Last but not least- it’s impossible to clean throughly .. heaven forbid your child have an accident or throw up. You cannot clean underneath it and the straps are impossible to remove without messing it up and having to buy a whole new car seat! I’ve washed it several times without removing straps but I wasn’t satisfied with that!

Started a great car seatI loved this car seat until I washed it the top fabric won’t stay on, not even a year with the car seat. It’s so frustrating to fight with this car seat. For the price I paid I thought it was a forever (more than a year ) car seat .

It’s ok but not for this priceChicco is known for its car seat quality but this one I think they missed quite few items.
First, crotch belt. Problem: only 2 spots, according to the manual of forward facing it needs to be at the first one. It’s a long belt which of you have a skinny coward facing child it doesn’t fit properly. The crotch goes on to their bellies.
Second annoying problem: really thin padding at stage 3. Thinking of Chicco I’d expect something way way better. But that isn’t the only thing besides the thin padding there’s openings that trap all the dirty in this entire world inside of the car seat. All the little surfaces that a vacuum cleaner can’t get.
Third one: there’s no place to hold seat belt out of the way when rear facing. Forward facing isn’t that annoying.
I have this car seat for almost 2 years now and I’d not buy it again if I needed or recommend.
For this price range and for being a Chicco I honestly expected way more.
Other than that, is easy to install with a seat belt or latch system.
Classic 9 position recline system is great
Easy to tight harness rear and forward facing

Fell apartSeat fell apart in less than a year of minimal use. Protective pieces - especially around head - are all thin styrofoam. I would not recommend.

Fit 4 BAD HEADPIEDCEI have only used this seat for about 3 months, and usually only about 4 times a week total. Today the foam padding of the head piece completely separated from the seat. You can see where hot glue was used on a few portions to affix the foam to the plastic. Terrible design. Submitted a warranty replacement request; awaiting response.

Car seatWe do like the new seat we purchased for our grandson. The straps are a bit challenging. His infant seat straps were easier. It also was a Chicco key fit system. These straps don’t seem to pull out as far so it is a challenge to strap him in. Hopefully when the snow flies and he has in a heavier jacket we won’t have issues.

Never buy from chicco website. Price is cheaper elsewhere.I like the product and its really good. However worst customer service. These guys dont price match. Paid $100 extra than the price listed in amazon. These guys have a store in amazon and sell for much cheaper price than their website itself. Never buy from their own website. If i have to return i have to pay return shipping as well. One of the worst purchase experience for me. Never seen any seller without price match guarantee.
Never give your email for their $25 or $30 off coupon, your mailbox gets flooded and spammed. One of the worst customer experience i had in recent years. You lost a customer Chicco.
How /where should I grab the seat when moving it out of the car? Instinctively I grab near the seat bottom and top head area. That caused the styrofoam to crackle and now it feels loose within the cover

Is this car seat compatible with the BOB Alterrain jogger?
Asked by: Anonymous
A convertible seat like the NextFit, Fit4 and OneFit are designed to face rearward for young children and then forward for older children. The NextFit, Fit4, and OneFit, like other convertible seats, are designed to stay in the car at all times and do not have a removable base. The OneFit, NextFit and Fit4 car seats are not compatible with any stroller.

Is there a weight limit to switch from using the anchors to a seat belt? If so, when should you start using the seat belt?
Asked by: Anonymous
In general, the weight limitation for using LATCH connectors on LATCH anchors is governed by the automobile manufacturer's rating of the LATCH anchors. In general, the weight of the child plus the weight of the car seat should be under 65 lbs. But always check your vehicle's owner's manual for the details relevant to your vehicle.
