Extremely hard to understand. And extremely hard to use. Very very very hard to get small baby in and out. Very frustrating product that cost a lot of money. Harness is incredibly hard to release. You better have a big truck or SVU. And not a small baby. Very very very frustrating and will never buy again nor recommend to anyone who asks suggestions.

But my one year old can now end the chest strap and pop it open so he then tries to work his legs out of his seat and we have to pull over and get him situated again. It's just not safe for us to keep him in here I wish I knew what other seats are highly recommended. I even tried looking on here to get the chest piece replaced but I can't seem to find anything.

So we changed to the maxi cosi from the cybex. Our son is a big guy and had outgrown the Cybex which we absolutely loved, but it wasn't washable so it was a nightmare. We love the maxi cosi but i've had to do a number of claims for ours because the harness strap doesn't full extend in or out so it's super uncomfortable for our son. But we were told that it does, well lies it doesn't it gets to about 5" in and that's it, it won't budge!! Kids are all built differently soo making it comfortable for our son is just not possible. Also the chest strap my son is able to bend it and it pops open, how is this even possible!!! His grandmother can't get it open but he does??? Our problem is that this seat is the only one on the market that has the weight max we need for him! So we're stuck!!

After my son turned 6 months, he had already grew out of his Britax infant seat because of how narrow the seat was and how chunky of a baby he was. I researched for a LONG time about different convertible car seats that way I wouldn't have to buy another car seat for him (unless the seat experiences a car accident of course). This seat is by far the best quality and SAFE car seat I could find. And THE FEATURES! The straps and buckle that automatically spring open are the best! No more hassling with trying to get straps out from under the baby! It also is so much more CONVERTIBLE than any other seat I could find. There are so many different height settings for the headrest and side pieces, and the recline keeps the baby at the correct position. Now, one thing about this seat: it's HEAVY, which is a con when taking it in and out of the car, but I would rather have a heavy seat if my child was in it and got in a car accident. I don't see the weight of this seat as a con, but more of a necessary evil. You can feel the quality of the seat both through its structure, design, and fabrics/padding. My son is so comfortable in this seat and sleeps so well in it! The extra head piece that comes with it keeps his head from falling to the side too far, and the recline keeps his head from falling forward. Now, cleaning this seat is a CHORE. Taking the fabrics off and putting them back on is complicated. I definitely recommend watching the video to help! It's very time consuming, so plan to spend a couple hours just taking it apart and putting it back together. The fabrics are machine washable and dryable, though I don't dry them to keep them lasting longer. Cleaning the plastic of the seat is also difficult because of all the nooks and hard-to-reach places on the seat. I definitely recommend using a toothbrush to get in them. The cup holders are removable and are dish washer safe too! Overall, this seat is safe for my child and will last the 10 years that it takes to expire!

I bought this from buybuybaby just a few months ago and the seat part where it zips is broken, so now the plastic part of the seat is exposed! have no clue how because we don't use the zipper! Contacted both buybuy and maxi cosi and no one has been helpful! I have no idea what to do. Please, Maxi Cosi contact me so that I can get a replacement for this defect in my sons car seat.

we took our toddler on the airplane to japan and the airlines lost the padding that goes in it. unfortunately I can't find any replacement bottom padding and head padding. so keep that in mind if you travel alot.

We got this carseat for our newborn since it said minimum of 5lbs, but putting her in it for the first time at the hospital was a serious hassle. She is 8lbs. & even after getting her secured in there, she just looks very uncomfortable and unsafe. We went out and bought an infant carrier carseat to use until she is bigger and can fit in this one better. It says 5lbs but I honestly would not recommend it to anyone for an infant. Overall I do like it and I will use it later on, which is why im giving 3 stars.
