    Love! Pricy but you definitely get what you pay for. Super easy to instal and adjust as baby grows. Definitely easier to instal than others. Sets the standard for car seats Apr 10, 2024

    The revolving part makes it so easy to put my LO on and off the car. She likes it from first ride and had no issue transitioning out of the baby carrier basket. We love the design and color as well. Jul 10, 2023

  • This convertible seat has multiple recline options making the seat very comfortable for my LO. The sensor safe clip is handy when needed, but as my husband drives off my phone gets critical alerts. Jun 27, 2023

  • LOVE this carseat. I have one for each car. The swivel is a MUST if you are short and have a large vehicle. Comfortable and ultra safe, I would definitely get this for Baby #2! May 24, 2023

  • Really nice car seat and features. Can be hard to install just right to where it’s sturdy. It is also kind of heavy so if you need to move it back and forth often it may not be for you. May 15, 2023

  • Have this in my husbands car! My baby seems comfortable and likes it but sometimes the straps have issues Mar 09, 2023

  • Really love this car seat Feb 19, 2023

  • Very safe when installed properly. Love the rotating feature that helps me get my big guy in and out safely while protecting my back. Jan 04, 2023

  • We are talking not only innovative, but safe! Im a petite gal and lifting my 30lb toddler with the 360 feature is EASY on my pregnant body already got another for baby n2. It is SAFE too! Sep 13, 2022

  • Just awful. So wobbly and definitely not safe. Ended up returning. Apr 19, 2022

  • This was the safest carseat I could buy and it has been great. We don't use the sensor, but it's a nice feature to have. No cons to the car seat. Feb 23, 2022

  • The rotating feature is a life saver. I love this purchase. Some people complain about install, but once done properly it doesn’t move ! Jan 12, 2022

  • Amazing, literally my toddler loves to get in the car and go places. This is a Porsche car seat! Nov 15, 2021

    Purchased this and the Sirona S. This is a great seat, I really like the safety features and quality fabric and design but we ended up going with the Sirona S for the swivel feature. Still recommend. Jun 02, 2021

  • Love the cybex car seats. I had the infant car seat and then got this one. Love it so much. The fabric, the safety, the ease of use and durability. My son also loves it. He is still rear facing at 2.5 Apr 29, 2021

  • Love this car seat, the safety features are amazing, it has its own app. The sensor tells you if your child is too hot, on wrong and best of all notifies your phone if the baby is left in the car. Mar 02, 2021

  • My verdict is still out on this product. Took me hours to securely install it and still having problems. Waiting for a technician to help me. It sway when i made turns. Also app is not great. Dec 31, 2020

  • Very comfortable, been using since age 1, easy head adjustment, easy to tighten and loosen straps Nov 10, 2020

  • I absolutely love this car seat, I have a Rava for my car and bought this for the nanny but the baby love it so much I moved it to my car! It installs with ease and he fits so well! Oct 19, 2020

  • Safe convertible car seat Aug 26, 2020

  • Used Cybex with first born, will use again with second. Top quality, European-make with exceptional safety ratings. Top of the line fabric. Lightweight. Has all the innovative bells and whistles. Aug 20, 2020

  • I am in love with this car seat. It makes getting my daughter in and out of the car so easy. It spins 360 and it reclines at a ton of different levels. My daughter loves it and it grows with her! Jul 03, 2020

  • I love cybex! All products we have are beautifully done and have a great quality and durability. This carseat is comfortable and secure. The sensor is also an extra help to make sure baby is secure May 23, 2020

  • Love this carseat! Both my 1 and 3 year old have this car seat. They fit very well in the car rear facing and forward facing. The cover is very easy to wash without having to rethread everything. Feb 03, 2020

  • We really love this carseat. It's super spacious compared to other ones so great if you have a larger baby/toddler and want them to not feel way too snug. The additional tech features are also great. Jan 30, 2020

  • Love the added features in this seat! The app notifies you if your child unclicked the harness, if it's too hot, or if you've left your child in the car. Puts me at ease, plus it's comfy for my son! Jan 17, 2020

  • The look & fabric is nice and modern. Feels very safe, however the install method needs improving. It left me questioning if I did it correctly. The Sensor Safe is great, but the loud chime is...loudd Jul 23, 2019

  • I like the look, comfort, and daily functionality of this car seat, however, it is EXTREMELY difficult to install properly. I will trade cars with my husband before I move the car seat to his car. Jul 16, 2019

    We have both the cloud-q and Sirona M. We recently put the Sirona in dad’s car and it is super sturdy and comfy! I wouldn’t recommend removing on routine basis, as it is bulky and hard to install. Jun 14, 2019

  • We bought this carseat because of the security features. The sensor safe is great for us as first time parents. Additional to that, its elegant and my baby truly rides in a great carseat! Apr 23, 2019

  • I love how compact this is. We were unsatisfied with a precious car seat we had, but this was a no brained. The chest clip even reminds you where placement should go (good for sitters and grandparents Mar 12, 2019
