Ease Of Installation

Sturdiness

Comfort

I will start by saying we LOVE this slender seat. If you're looking for something that is safe but yet minimal this is the seat! 

(((( I want to plug this in here because I know when you have a smaller vehicle you have to do your research to find seats that fit-
I have a 2018 Toyota Tacoma 4 door. I am 5'4” and my husband is 5'10”.))))

My almost 4 year old was not at all pleased with any of her convertible seats and I was over hearing those complaints. The design of convertible seats always guide little legs/feet to go up and straight out forcing feet on the back of the front seats. Convertible seats are so darn bulky. 

With the Diono she can now climb into her own seat! Big sister can now comfortably ride in the middle.. the Diono fits in the middle seat too. There is space to comfortably have 2 other kids or 2 adults next to this seat. It's seriously doesn't take up any extra space at all! It seems like it's just a manufacture add-on to the vehicles seat. It looks almost like an aftermarket 5 point harness adult seat (but mini). It's narrow, sleek and awesome! 

I was told these are notoriously hard to install so I  fueled up on some carbs and was prepared to get a good sweat on... but it was super easy to install forward facing with the seat belt (phew). 

If you're going to be rear facing you would have to install in the middle. I wouldn't use this seat for a newborn. 

We did purchase two cup holders but if you want you can order 4 cup holders. My little isn't the biggest fan of the large chest clip pads but she forgot about them after 2-3 car rides.

Yes!

Although this car seat is so heavy you won't be throwing It around, the ease of putting the child in and how well the child likes to sit in it is amazing.

Car seat is worth the extra money

Ordered 2 of these car seats for my 2 yo and 4 yo so I could fit 3 across in my Santa Fe. Overall very pleased with them but when rear facing it takes up a lot of depth- we opted to turn my 2 yo around earlier than intended.

Mom of 3 looking for slim fit seats

They worked great for my grandchildren!! They are narrower & can fit three car seats in a row! PERFECT!!

IT WORKED!

Love love love the car seat no instructions but you can find them on line really easy and fast to install

Easy to install

I bought three of these seats to replace the three we have now. I love them. Heavy duty, strong, padded, safe and my kids are comfortable. They fit three in a row in my 2021 Kia Sedona. Very happy

Does indeed fit 3 in a row

Great car seat, this is our second seat but I didn't want to compromise on safety and comfort. This seat meets both of those standards big plus is its travel friendly.

Great car seat and very comfortable.

Very sturdy (read-heavy). Both my 7 yr old in forward facing booster and my 1 yr old in rear facing harness are very comfortable. My 9 yr old ( who has to sit in the middle) has enough room too.

Great car seat

This thing is super heavy. It says 3 across but dont be too confident. It seems to work ok to have 3 of these across the back seat if our 06 honda odyssey but still. Just ok but these are the only seats i could find.

Ok, these are crazy heavy

I like that it takes up less space than other front facing seats, however with that it seems like you're losing some of the side support.  It doesn't have a level feature like other seats do.

Slim fit
