Safe, affordable, & comfort all in one!!!
Great car seat! Itâs sturdy & very sheik I love the easy cleaning fabric it has, it is very heavy which makes me feel like my baby is safe in it! Itâs got adjustable shoulder straps & head rest adjustments as well so it can grow with your baby. The seat part also has side adjustments so it can be narrow or wider which is a neat feature! I wonât be using it for travel but it folds up and could be easy to transport if you can carry the heavy weight of it. For the price of this car seat it was a steal!!! We spent double on a Gracie brand before and i feel this car seat is much safer, itâs also roll over tested which is great because not many car seats have that. I will say the cup holders are terrible they fall out very easily but I rather my kid be safe than have a cup holder!!! I was able to fit 2 of these car seats in with a Doona in my Ford Escape 2018 which was suppose to be impossible but the fact of how compact it is made it possible, my boys also say itâs very comfortable which is a huge bonus! Definitely a must buy car seat!!!

Very very sturdy and strong probably one of the best on the market
Love the seats after having a car accident we decided to go for a much stronger and sturdier seat and this came in at top of the list they fold nice and flat for traveling on planes and things but just be prepared they are very very very heavy so would be hard to carry around a airport with child in arms also a little hard to instal but well worth it in the end love all the cool colors u can also choose from

Fits 2 in a row with additional infant seat in Toyota Camry!
We bought 2 of these to fit in the backseat of our 2010 Toyota Camry. 1 rear facing, middle forward facing, next to infant (Uppababy Mesa) seat. Middle forward facing was the only way it would fit.Proâs: slim, sturdy, easy for our kids to get into themselves, latch system is easy/works well. Good customer service from Diono. Our first one didnât have the rear-facing piece in the box.Cons:* Very heavy!* Tall backside. Check your car seat manual whether a car seat is allowed to touch/rest against the front seat (if rear facing). Now having moved one to the middle back seat (forward facing) on our Honda Odyssey, it sits higher and blocks the rearview a bit. Wasnât an issue in the Camry.No cupholders- fine, since that wouldnât fit anyway.Not as much padding, so perhaps less comfortable, but both our kids are fine in them.Overal conclusion: great car seat if you have a tight back seat!

Favorite Car seat
This is my favorite car seat. I am soon going to have 3 under 3. I am planning on switching all car seat to this one. They fit in all 3 of our vehicles nicely and securely. (We have a SUV, Sudan, and Truck). Which we have had problems with other brands not being secure. They are really easy to move from car to car. They are a little heavy but I donât find that to be a problem. I find there price to be very reasonable. I have fortunately been able to buy both of mine when they were on sale.

Great product, seat cover only downside.
We have had this car seat a year now. Overall love it. It is trim and easily helps put 3 car seats in my K5. I only gave it 4 stars though as the car seat cover has some wear and tear. I have an older Greco seat cover that looks like new.

Best for price, hands down 5 stars
Ive had several different carseats. This is by far the best… its sleak… narrow at bottom… installation staps have a much better design by pulling a little strap rather than have to push a button deep into the seat. This is the very best carseat for price, especially if you have multiple children in a more condensed space. 5 Star through and through

BEST on the market
Best car seat Iâve ever owned, ended up buying by the second one a week later for the other car. Wish I invested sooner for the other kids

Love!
Love this brand of car seat. The safety aspect is why I went this brand, love that itâs narrow and you can fit 3 across. Cleaning this car seat is a breeze, the cover comes off for it to be washed. I have 2 of this exact one and then a high back booster of the same brand. Great quality car seats, easy to install, easy to clean. Highly recommend this brand to anyone with littles.

Ocupas ser un Ingeniero Aeronautico o automotriz para Instalarlo. Es demasiado Dificil su instalación. Pero brinda buena protección al BB

100% recommend. 2 seats were delivered in 1 day! Now all 3 of my kiddos will fit in the car **07 hyundia sonata** and they fit with room between to buckle my oldest who is using a seat belt, easily.Ectremely comfy. The chest pads are like gel and thick. My infant son now loves his car rides. So excited and happy with this purchase. And save on space. Appose to buying a larger vehicleOnly complaint, didnt come with instructions but I feel as though it is self explanitory and super easy use and instalation :)They are heavy but makes me feel better about the kids saftey if there ever was and accident.Also note to add the rear facing did not take up any extra space. I did not need to move the front seat any more forward than I already had it from out previous seat .

It’s a wonderful carseat and is definitely more narrow than other seats. Granddaughter loves it’s and was so happy she could choose the color. The color is beautiful and vibrant.

We bought these specifically for their narrow size for aeroplane travel with our kids (3, 5).They fold nicely and can sit on top of your luggage. We used a small crank tie to attach it to our carryon as it is awkward and a bit heavy to carry on a long walk through an airport terminal.But it fits nicely in aeroplane seats, they are very quick and easy to install in both cars and planes. The pull strap to secure your child is a lot easier to use than other car seats we have used.These are a bit pricey, but are absolutely worth the cost.
