we purchased the car seat when we found out we were pregnant. unfortunately, we lost the baby so didn't get to use the car seat until we had our rainbow baby last year. we had similar issues as others- the sun canopy is completely useless, and it's difficult to release and maneuver the handle. FINE, we put up with it UNTIL the Styrofoam mysteriously SNAPPED IN HALF one day. We were not in an accident, we did not manhandle the car seat. it just broke. we tried the customer service (can only submit a form via the website) and ended up using facebook messaging system because NO ONE was getting back to us. since we had the car seat and never thought we'd have to deal with this, we didn't keep the receipt. even though we registered with the cybex website apparently that info is only used for recall purpose, and cannot be used a proof of purchase. All we asked for is the styrofoam replacement which they denied us, AND IT CANNOT EVEN BE PURCHASED. instead we were asked to tape it and glue it together... WHAT? the foam was snapped, broken, in half. the seat cover can't even stay on properly and we are supposed to MacGyver it so we can transport our baby in it? Anyway, just terrible. WILL NOT RECOMMEND.

This is by far the worst car seat! Nothing on this car seat works properly. The sun canopy doesn’t even cover babies eyes. It’s always a struggle to get it up or down. The car seat is extremely heavy and makes my baby so hot and sweaty. My baby cries the second I put her down until I take her out. I don’t go out with her unless necessary just not to deal with her screaming. Terrible, TERRIBLE PRODUCT! As mother’s we already have a thousand things to worry about we shouldn’t have to struggle with a car seat. This car seat was not made with baby and mommies in mind!

Disappointed BB&B Customer ·

Buyers beware, very pricey and not the greatest. We purchased this since it came highly recommended by the sales agent at BuyBuyBaby store. He sold us on the safety features, which are the only things we like so far, however, we dislike everything else about it. The handle gets stuck on the sun shade. You have to yank on it to get it unstuck. You have to use two hands to unlock the car seat from the stroller base which makes it hard to grasp the handle. Baby is 3 weeks old and I can’t imagine how it will be when he is bigger and heavier. The handle on the car seat gets stuck to move up and down as well. You have to yank on the stroller to fold down. Besides the safety features, the car seat and stroller are not ideal for ease with having to constantly yank on either one to work properly. Spend your money on a different product if possible.

Questionably Made and Unsafe DB1212 ·
Recommended Not Recommended

I bought this car seat and two bases to go along with the bugaboo stroller. I spent a lot of time reading about the different car seats and decided this was the best suited. After a couple months of us use the canopy broke due to a crack in the frame. After multiple attempts, pictures and emails to the company, a pointless sun canopy replacement they finally agreed to replace the car seat. Shortly after using the replaced car seat I leaned over to get baby out and heard a large crack. The whole right side of the Styrofoam completely broke free from the seat. I was shocked and knew immediately this wasn’t safe. I sent pics and an explanation to the company and they responded this was not a manufacturer defect and because the styrofoam had a clean break and no missing “pieces larger than popcorn” it’s fine. I couldn’t believe they think this is safe for little ones. The structure of the seat is wobbly, unstable and the seat restraints are now affected (pics below) The car seat is completely unusable, falling apart and clearly not safe. Spend your money elsewhere.


We are sorry to hear your attempt at getting the issue resolved was unsuccessful. We would love another opportunity to rectify this for you. If you will be so kind as to email us at, paste your review in the body of the email, along with Amazon review as the subject; we will gladly have our staff reach out to you for assistance. cybex

I hate this car seat more than anything Candace ·
Recommended Not Recommended

This is the most difficult to install and use car seat. You have to adjust that dang base constantly because it comes loose or shifts to the wrong level. Speaking of, the little ball level is a pain. Why on earth is it on the bottom where you can’t see it if the car seat is hooked on. And it gets stuck in the level and you have to shake the base for it to even budge which then loosens it and you have to start all over again. I fight with this thing on every car ride having to take my baby out and mess with it. This was supposed to be the safest car seat out there but it’s difficulty of use makes it unsafe because you don’t know if it’s going to shift or even installed right. The strap to pull and tighten the harness is hard to maneuver. You have to pull really hard to get it to tighten which 1. Is hard to do. 2. Very scary when you are pulling this hard with your newborn infant in the car seat. I bought the stroller with it and I’m still learning new features 5 months later because the stupid instructions have NO WORDS and it’s nearly impossible to find anything on how to operate it online or on YouTube. I recently bought a graco car seat for my other car and have had 0 issues with it coming loose during transit and it took all of 15 minutes to install and use so it is not user error on my part. This company needs better design and instructions. Only buy this car seat if you truly hate yourself.

DO NOT PURCHASE!!! BB&B Customer ·
Recommended Not Recommended

PLEASE DO NOT CONSIDER THIS SEAT! I have 4 kids and needed a new car seat for my 4th child. I had used a hand me down britax for my first 3, which held up beautifully. I thought I was "upgrading". Let's just say, my son is 14 months old and the car seat is not longer usable. The canopy (which i pretty much a piece of flimsy fabric) has entirely fallen apart, and this evening, the cover came off to reveal that the foam inside the seat is cracked all the way from top to bottom!!! No we were not in any car accidents. I am baffled as to how this happened. I am so disappointed. This car seat should not even be allowed on the market. I am going back to Britax.

Annoying Base clip Huda ·
Recommended Not Recommended

The base clip is the most difficult thing I have ever used paying all that money for something that says it will protect your child but fails to clip when you need it… I rather use the cars seat belt and I’m not happy about that! I need to know my baby is safe with the car seat base… at this point I wish I bought a cheaper brand I’m sure I wouldn’t have these issues.


We are sorry to hear of the disappointment and issues you are encountering with the usage of the seat and would love the opportunity to assist. Please reach out to our Cybex customer support team at 877-242-5676 and any representative will be happy to help. cybex

I purchased this car seat after a lot of research and was really excited about it since it would clip right in to our Cybex Gazelle S stroller (which we love!) but the car seat ended up not being great. Not very easy and quick to clip in and out of the base in comparison to other car seats on the market. It would be faster to use this car seat with the seat belt instead. The handle was impossible to adjust without two people since it would catch on the sun shade which I think was a defect. The seat for our baby was very comfortable though and it looks nice.
