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.

Lightweight, easy to install, and spacious—great for travel!
I purchased this car seat for our little one specifically for travel, and it’s been a fantastic choice. Key Features Lightweight: This car seat is incredibly lightweight, which makes it perfect for travel. It’s easy to haul around without too much effort. Quick Installation: Installing it front-facing is super quick and simple, which is a big win when hopping in and out of Ubers or rental cars. I haven’t tried rear-facing, so I can’t comment on that, but the ease of front-facing installation is a huge plus for us. Spacious: The seat is very roomy, which works well for our ever-growing toddler. It’s comfortable and gives them plenty of space without feeling cramped. Ease of Cleaning The cover is easy to remove, which makes cleaning straightforward. However, since it isn’t water-resistant, you’ll need to plan for drying time if there are accidents and you don’t have access to a dryer.

great buy if you can stomach some inconvenience
Love this car seat for the most part. I have one in each of my cars. It's pretty decent for the money. It's narrow so it takes up less space in my forester, allowing two to ride in the back with the seat. It was a huge upgrade in comfort when we got it when my son was two and is nicely padded. It's pretty easy to take apart and wash, way more so than the graco infant seat I had before (and my son is a puker, so I've done that a lot) and so far it seems to wash well. It does have some drawbacks, however. The buckles are pretty stiff and a challenge to get undone at times. I've had my other one for a year and it doesn't get better with use. There is also a serious learning curve when it comes to installing it rear-facing. The first time is kind of a nightmare, once you get the belt adjusted, it gets much better. It's a challenge to even figure out how to do that however since the instructions for rear-facing seemed to me to be almost non-existent. At a certain point I thought I had made a horrible mistake and inadvertently gotten a forward-facing only seat. I think the forward facing installation was much more thought out, because it has s much easier. The weird thing with this particular color is also that it is getting weird darkish patches as I wash it. Not like stains, but like the dye is washing out. It's starting to look kind of bad. But ultimately it's a very good car seat for the money. I'm not looking to switch any time soon and I have bought two! UPDATE: I've had this seat for about a year now and my little one finally maxed out the rear facing so we flipped him forward facing. WOW. I love this car seat so much more. It is a breeze to install forward facing and fits nicely in both our Enclave and Forester seats. its secure with seat belt or anchors and is still comfortable. If you are buying for a forward facing kid, it is so much more convenient.

Great for the price
In terms of cost, I think this is a pretty great, basic car seat. There’s no fancy “bells and whistles” included that some other models may have, but it does have a cup holder, and a headrest that is easily adjustable. We’ve had this car seat for about a year now and it’s held up perfectly. Easy to clean, travel with, and secure into your vehicle. We’ve only ever secured it with the seatbelt. Pros: The Onyx color is lovely, we didn’t want anything too bright or flashy and the color in person matches the picture. It seems comfy, I’ve obviously never used it personally, but my daughter has never seemed to have an issue. Lightweight. Pretty compact in size compared to others, we have a very small vehicle (Chevy Spark) and this fits pretty well without looking very bulky. Although, it doesn’t fit in rear facing position without moving the passenger seat as far up as possible. Cons: The straps twist constantly in the bucke part. I don’t know if I’m doing something wrong, but I can’t seem to stop it from happening.

Works great
Great value. I bought this seat for when the grandbaby comes over. She is 32 lb. This is a great seat that should last for years. Not bulky. Easy to take in/out. I use the latch system which is easy. Install it only when needed. Once you practice, you can install in under a minute.

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 didn’t have that. My little guy absolutely loves this car seat because it’s much roomier than his infant car seat. I would definitely buy again!

Loved it at first - now I’m annoyed.
When we first bought this seat - I was super excited because it’s so slim and fit wonderfully in our car! We used it forward facing for our 2.5 year old, and it was good. When she fell asleep in the seat - I seriously thought her neck was going to snap, or she would stop breathing. There is zero head support. Now - we’ve purchased a second one for our one year old twins. Using them rear facing makes me regret buying them. Adjusting the seat is a joke. To make it safely level - the instructions recommend rolling up a towel to stick underneath the front of the seat. For the Price, this shouldn’t be the only option to get your car seat level. I was so frustrated I almost returned it. Rear facing, there is also zero head/neck support and I would NEVER put an infant in this seat. I worry about my one year olds closing their airways - I can’t imagine how it would be for a foppy headed infant. Overall, this is our only option because we have five kids that need car seats and this is the only thing that will work in our van. But the second I find something better with the same width, these are gone. So - long story short. If you need a slim car seat to fit three across in the back or to wiggle it between your existing car seats, this is probably your only option. If you don’t need this for it’s width - I wouldn’t recommend it.

Very impressed overall and will buy again
These are amazing! I just ordered 2 and they were easy to set up and install. - The fabric feels quality and easy to clean. - The latches are super smooth but not too easy that a child could open (I can do it one-handed which is huge for having 3 under 3). - The install was NOT bad! Did it take a little brain power? Yes, but so has every other car seat I’ve ever owned, and once I figured it out, these card seats were in there soooooo snug! Very stable - Removal was also easy because the releases are made super well! - Weight-wise, these are pretty light compared to my Graco convertible seat - I looked up safety ratings and these ranked equal to the graco convertible seat they my oldest is in!
