The perfect carseat
I’m not sure how it fits a newborn but I got a great install for a 1 year old. Much better fitting than the Graco DLX. Heavy and sturdy. Easy to adjust the straps, latch, and headrest. Easy to use. Fairly easy to clean compared to other seats on the market.

Great Seat
I love this car seat. I did a TON of research looking for the perfect seat to transition my child to and ultimately landed on this one. I wanted a seat that was safe, free of chemicals, and could also be rear facing as long as possible. This seat checked all the boxes. We have been using it for close to a year now and my girl loves it. There is a good amount of padding and she is very comfortable in it. It is also so simple to put into the car- the latch system is super easy to figure out.

Well made and feels safe with ability to install tightly.
Heavy duty well constructed car seat. A bit heavier than expected but very sturdy. Buckles and clamps work fine and secure tightly in car. I’d recommend it.

Chick Car Seat
Very sturdy and well built car seat. Easy to install and transfer between vehicles. It is on the bigger side, but fit comfortably in both a crossover and truck.

Roomy and quality material
This car seat is very comfortable for my baby, he enjoys car rides much more now that he has more room and sits a little higher than the infant car seat. It has plenty of room for growth. The straps are easy to adjust. The car seat is easy to install. My favorite thing about these car seats are that they are made with clear tex materials, meaning the material is already flame retardant without any added chemicals to make the seat flame retardant.

Safe and comfortable car seat!!
Car seat provides a good, secure, and comfortable, padded seat for my grandchild. It’s being g used right now for facing to the back but will be used later in a forward sitting position as our grandchild grows. It’s easy to move from vehicle to vehicle when needed. As it faces towards the back now our baby is able to sleep in the car seat. The car has a degree of tilt monitor on the side. Mom and dad love this car seat it will be used for quite some time and they now have peace of mind for safety when in vehicle.

Good Buy
Great carseat, just a bit clunky and somewhat hard to loosen the straps to get baby out. Otherwise, I love the look of it and hope it maintains safety.

Solid Car Seat
Great car seat – quality is really nice, the seat feels solid but comfortable for the little ones. It is adaptable to a lot of ages which is nice so you dont have to keep replacing your car seat. Easy to install (similar to most others) and very secure. It’s a bit pricey but worth it in my opinion.

Era un producto de importación, llegó antes de lo indicado, completo y en buen estado. Respecto a la silla, es muy recomendable, se puede colocar hacia atrás, adelante o utilizar el boost con el cinturón de seguridad para niños más grandes!
