- Reviewed in the United States on May 19, 2023I ordered one carpet initially because I was worried it would be poorly made due to the great price, but it's very nice. It keeps my baby comfortable and safe. Plus it was so easy to install. I ordered a second one for my husband's truck.
- Reviewed in the United States on October 19, 2024We tried to take our son home from the hospital in this carseat, but it was WAY too big. Once he hit about 6 months (he's a big baby) he made the 20 lb mark and this carseat was perfect. Lots of room to grow but secure and a decent size.
- Reviewed in the United States on June 25, 2022This car seat keeps my son from getting any injury’s in our car accident this week. We were hit by a Ford F-150 that was traveling 45 MPH as we were taking off from a stop at a 4 way stop. He ran the stop sign and totaled my 2011 Ford Focus. My son, 1 year old, was the only one not injured in my car. The seat did everything it was supposed to! It protected him from impact, we did have the sides bumped out as he was behind the drivers seat at the time of the accident. This seat did an amazing job and I am forever greatful for this company and how much thought went into safety features! Amazing car seat! I’ve attached an image of my son buckled into the seat and then 1 image on my car and an image that shows the truck that hit us along with my car. I give this car seat all the credit as to why my son wasn’t injured!

Images in this review - Reviewed in the United States on February 24, 2022I loved the safety features and all the extra padding, etc. Plus Amazon had it on sale. It gets here in three days, box was beat to hades, but inside everything was still plastic wrapped, zip tied, etc. It’s so nice. Cadillac nice. Black Lincoln nice. The padding is amazing, you don’t have to re-thread the harness, and the level indicator is a lovely added touch. I especially loved the L.S.P. feature, it just makes me feel better even if it sounds gimmicky.
However, it’s extremely hard to install. I have a newer Kia Sorento so it’s not the smallest SUV, but you wouldn’t know it putting this thing in.
The best rear facing level we could get was a 3, (1 is for newborns for reference) and even though my daughter is almost a year, I would have liked to get it to a 2. The anchors would never tighten down to where I felt they were safe. I know you can only use them to 35 lbs, but we couldn’t even use them for a little while. With the seat belt, it’s super tight and secure but the lock off feature is almost impossible to engage unless your husband manhandles it, and even then he could only get it halfway.
When it’s all said and done, she’s very comfortable and it’s easy getting her in and out of the vehicle. But I dread having to fix it if for whatever reason it gets knocked out of position or must be moved.
All in all, behind the driver’s seat (I’m 5’6”) was where we got it safely in and leveled properly. It would not fit in the middle, and the passenger side worked, but the front passenger seat had to be moved so far up, my husband couldn’t get in.
It’s lovely, but buyer beware of how large it is and how difficult the rear facing installation is.
- Reviewed in the United States on January 25, 2023I have been using this seat for about 2 weeks now and I love it. The only issue I have is that the instillation was difficult. I am certified in car seat instillation and this one was tricky for even me. It took me longer than it has even taken me to install a car seat. But with patience I finally got it right. I hope to never have to move it. Rule of thumb - the car seat should not move more than an inch side to side. Have someone else take a look if you are having trouble. It’s better to be safe than sorry. Other than that, I absolutely love it. It’s not too wide. It’s very comfortable and cushioned. The winning feature for me is the reclining headrest. It’s like magic. It keeps your little one’s head from falling forward while asleep. I used to drive with one hand while the other was in the backseat holding my son’s head up. No gimmicky pillow or hack worked for us. This feature alone is worth 5 stars.

5.0 out of 5 stars excelente compra
se siente de muy buena calidad, como punto importante el echo de que permita que la parte superior se incline ligeramente hacia atras es perfecta para el niño, esto le pemirte ir dormido con la cableza ligeramente inclinada hacia atras en vez de que se le caiga hacia delante como le pasa en el resto de sillas que he probado

4.0 out of 5 stars Calidad, comodidad, seguridad y fácil instalación
Hoy la use por primera vez y siento que hice una buena compra, mi bebé se fue tranquilo y comodo. Al principio cuando llegó pense en regresarla por que la fecha de realización de la silla es del 2021 por lo que ya tiene 2 años menos de los 10 años que tiene de vida, pero al final no decidi regresarla por tres cosas.
1. Espere casi 3 semanas para recibirla desde US y la verdad es que ya nos era necesaria.
2. Amazon tiene el mejor precio.
3. Es la silla que más me convenció del mercado y sinceramente puedo decir que no esperaba más, cada detalle me convenció, la calidad de los materiales es excelente.
Crei que iba a batallar mucho para instalarla, ya que jamás habia instalado alguna, el manual es explicito como los videos que vienen en su pagina oficial.
Cybex es una marca que ofrece innovación y seguridad, lo digo por que ya es el segundo producto que adquiero de esta marca y sinceramente seguiria comprando.
En resumen, estamos contentos con la compra.
