Great value for price!
I debated what car seat to get for my child once he outgrew his infant car seat and love this one. I thought it was easy to install and fits well in my car. We still have it rear facing so it does take up more room that way but my 6ft husband still fits comfortably in the front passenger seat with our little one behind him. Other people reported some type of chemical smell but ours didnât have that. My little guy absolutely loves this car seat because itâs much roomier than his infant car seat. I would definitely buy again!

GREAT for the plane & traveling – subpar for a regular daily use car seat.
We bought this specifically to use on the plane ride and while on vacation. For the plane it worked perfectly (for a 14 month old). It is super light to move around and narrow so it fits in the plane seat.When we used it in a car, it wasn’t great because it is a fairly low quality car seat, it sits weirdly on seats so when our son fell asleep his neck tipped over really far and it looked uncomfortable. We had to use a second item to prop the car seat backward and make it the correct angle in the car.HIGHLY recommend for plane rides & travelling!!!!! Don’t recommend for daily use in a car.

Comfy, basic, difficult to install rear-facing
This seat is plush and cool, so my kids are very comfortable in it. The materials are great, the size is perfect, the safety ratings are reassuring, and the price is amazing! This is a bare bones seat, though. It has no convenience features like an easily adjustable no-rethread harness, or a level so you angle is correct. However, that is reflected the VERY affordable price (about $85) The only issue I have with this seat is that it is a huge pain to install it correctly and securely in a rear facing orientation, especially if you have deeply contoured seats.PROS:- Great rear facing height and weight limits- Higher forward facing weight limit than almost any other seat in this price range, allowing your bigger kid to stay in a harness longer. My 4 year old is almost 45 pounds, so this 65 pound forward facing limit will allow him to stay on a harness for a few more years, until he is ready for a belt positioning booster.- Relatively compact size, with straight sides that make it easier to fit next to another seat.- Comfortable, cool fabric. Won’t absorb heat like a dark seat if you live somewhere hot.- Plush seat!- Machine washable cover.- Cute styling! I got the aqua blue for both my son and daughter and they love it.- Easy forward facing install.- Lightweight and easy to carry for travel.CONS:- Difficult to get a tight installation rear facing.- Does NOT fit 3 across in a Jetta.- Tedious to rethread the straps and adjust the headrest.- The button you have to push to loosen the straps is buried under the cover and not marked, so it isn’t easy to find and use.All in all, this is a great basic seat for the money!I use them as travel seats and back ups in our second car. This seat won’t work well for someone who needs to use it for different children, as it must be removed from the vehicle to adjust the headrest and strap heights. It also wouldn’t be ideal if you were going to be moving it from one car to another frequently, as the install isn’t as quick and easy as it is on models with more convenience features. But it’s safe and sturdy and does its job, and you really can’t beat it for this price!

Simple & great
Ordered this to go into grandmaâs car when my kids are with her. Itâs super light weight. But definitely hard to secure into place. Doesnât look very comfy, and thereâs not like head rest. But at the same time, youâre getting what you pay for, so value for money, I think itâs great. Itâs pretty small which is great for saving space or in smaller cars.

This seat is everything I had on my check list…..
I bought this car seat based on design and price. I did quite a bit of research both online, reading reviews, and in stores. I couldn’t believe how expensive car seats are – going up to $300! With twins I needed something reasonable. The first feature I was looking for was a design that they would be able to sleep in without their head falling forward. My 15 month old twins do a lot of sleeping in their car seats. I wanted a well padded seat. I wanted a simple design, especially one that would be easy to keep clean. I wanted a compact car seat. And I wanted it to fit up to 65 lb. So there was my check list. This seat checks every box. It is everything I was hoping for. My babies really like their new seats and being able face forward and look out the window. The seats are well padded and comfy. They are compact. They are a no fuss design, simple to use. And my babies are able to sleep in them! The one tip of advice I would give though: in order for my babies to sleep in them comfortably without their head going forward, I pulled the car seat forward on the seat and folded in the back stabilizing bar. The first time I used the seat with it all the way upright and against the back of the seat,their heads did flop forward when they went to sleep. But with it pulled forward the angle is perfect now. The cover is easy enough to take on and off for cleaning and I love that I can just throw the whole thing in the wash. And they are affordable! If you’re looking for a simple and comfy chair, this one fits the bill.

Great for forward facing
This is extremely difficult to install rear facing in some vehicles (our truck and our SUV with bench seating)- we ended up getting different car seats because it was so frustrating. We had missed the return window and found that it is easier to install rear facing in bucket seats (grandmas suv) and very easy to install forward facing in any vehicle, and works great for that (when your child is big enough). It is slim yet very comfortable, and lightweight making it good for travel (I canât imagine lugging our Britax car seats through the airport⦠this Cosco seat is much better for that). Because of how difficult it was to correctly install rear facing, I would not recommend this carseat UNLESS you are looking for something forward facing.

Me gusto el tamaño y lo facil de instalar. Y el color.Realmente usa un espacio considerable para poder colocar mas sillas o si el auto es muy compacto.Pero no creo que sea apta para un bebé menor de 6 meses al menos pues todavia tendria que adaptar unas sabanitas enrrolladas a los costados de mi bebé para que no quede muy flojo en el asiento.

Es ligera, la usamos no como silla de diario ni para trayectos largos. Se usa en auto de familiares.
