Very Stylish, and super safe!! ASH23 ·
Recommended Not Recommended

My brother has these for his little one in both cars. Surprisingly didn't take up much room in his corolla and pilot. The install was fairly simple, the LATCH clips are actually in a little compartment underneath the seat pad (its mentioned in the instructions) And the Sensor part of it, was fairly straight forward too. I really like that this has the side impact protection pod things on the side, and the sensor features are really cool. I travel a lot, and wish my seats were this comfortable, outside of the sensor which is awesome, the headrest actually reclines, so the kids dont have bad posture or neck issues if they fall asleep (I'm sure there is some other type of safety reason but that is what comes to my mind on it) it just looks more comfy plus the extra padding all on the seat portion. I am glad we got these seats, he can also use them til the kids are at least eight years old, and my brother tells me he gets a ton of compliments on them. highly recommend.

Do not waste your time sarahb ·

I love everything about this seat as far as styling and comfort, but it is not safe to use. The plastic around the tightening strap pops out making the seat impossible to stay tightened. The end of the harness strap has come unattached from the tether hook inside the actual seat multiple times. This seat is a closed system seat and should absolutely not come unattached like it is. It is unacceptable. We are already on our second seat from cybex and this one has the same issues as the first. Until they get the issues worked out this seat is not safe to use in my opinion.

Too difficult to install Tbbb ·
Recommended Not Recommended

I was extremely disappointed in this car seat. I had such a difficult time trying to install it in the rear facing position, I couldn’t get it installed correctly and had to return it. I read the instructions and watched a few you tube videos with no luck. The latch system wouldn’t get the car seat installed tight enough and the positioning of the belt path made it literally impossible to cinch down the belt. I never write reviews but had such a bad experience with this car seat. It also did not seem comfortable for a child to sit in and is very wide, making it difficult to fit three people in the back seat if the car seat is installed.

Difficult to fit in car Kate H ·
Recommended Not Recommended

Love the features, the fabric, the look, and it seems like it's really comfortable. The problem is its size, it just barely fits in my car (a Kia Soul, not a tiny car)--I had to move it from behind the driver's seat to the passenger side so that I could put the seat back safely and now my passenger side is pretty squished. I read reviews that this was a concern in small cars but really it seems like it will only fit comfortably rear-facing in a very large vehicle.

Granddaughter loves it!! Sherri ·

We bought this for our 8 month old granddaughter who was visiting with her parents from Warsaw, Poland. We needed a car seat that will grow with her. We have traveled the states of Ohio & Indiana. She is comfy and sleeps soundly in it. She coos at us & plays contently while traveling. We are all very pleased with our purchase!!!



Terrible car seat BB&B Customer ·
Recommended Not Recommended

I HATE this car seat. The big selling point for us was that it had the safety sensor buckle but from the beginning it never really worked correctly and now it doesn’t work at all. Over time the straps have become nearly impossible to tighten all the way and this is overall a terrible car seat, especially for the money. After only a couple years we are already looking to buy my toddler a new car seat because this one is so terrible. Save your money and buy a different car seat!

Bought this seat for the value and the extended features . Super comfy and safe . A little difficult on install , great seat !



This is a GREAT and SAFE car seat Emily ·
Recommended Not Recommended

I’m so sad to see all of these negative reviews leading other customers astray. This is such an amazing and great quality car seat. I recommend it to EVERYONE. I truthfully feel there is no safer convertible car seat on the market. My straps have never “come loose” and if they did, all it takes is a return to the store for a replacement seat that is working properly. We used it rear facing and now forward facing for my oldest. No complaints at all, in fact I’m going to buy another one for my other son today.

I wanted to love it Best BBB Customer ·
Recommended Not Recommended

I really wanted to love this seat. It was fairly simple to install the lock off was a little tricky to slide the belt into but after the first couple times it was easier. I LOVE the reclinable headrest and am so sad I am not keeping the seat to use it. The forward facing height limit was very disappointing. I have a smaller 7 year old who typically sat in my graco forever seat no problem. In this seat her ears are almost to the top and the straps are so close to being below her shoulders. I couldn’t imagine using this as a booster beyond the 5 pt harness.
