Great Slim Carseat

If you have a smaller car and need to fit more than two carseats in the backseat, this is perfect for it. We had been trying to fit 3 carseats in our granddaughter's car for her 3 kids and it was a struggle until we found this carseat. It saved us!

Yes!

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.

3 across Acura MDX

We have five kids to transport, two rear-facing, the rest in boosters. We need every seat in the SUV. When we transitioned baby from infant to convertible, I tried the Graco Slim fit, and it was too big. This seat fit easily, no problems. So middle row is backless booster, diono, and graco extend to fit. So glad these are affordable now. Happy with it overall. Baby gets really mad when his caseworker has to transport him in the infant seat now that he's experienced the diono. He likes his big boy seat!

Checks all my boxes!

Really good seat. My daughter tends to sleep on long drives and this allows her the comfort to do that. Checks all my boxes on safety, comfort and ease of assembly. I'm certain she'll have this till she transitions out of car seats

3 fit in the back row!

I love that 3 fit in the back row of my Honda Odyssey. I have a 3 yr old and twin 1 yr olds. I have 2 bigger kids that cannot go in the back. These carseats have solved my commuting problems for the next 5 years!

Good for needing to fit 3 car seats in a row

Good carseat! Slim, I can now easily fit 3 kids in the back of my sedan. Can be tricky to install but watching videos helped. It's heavy due to a steel frame but it also seems very sturdy. Folding is a nice feature for storage!

These car seats are amazing. I have a Subaru crosstrek and 3 of them fit in my very small backseat ! Highly recommend for anyone not looking to upgrade their car.

Well made seat

The car seat is very easy to install and just as easy to adjust. I do wish there were some sort of attachment for a sippy cup (I knew when buying it did not come with one so this did not effect my star rating) I have a 2014 ford focus hatchback and it gives much more room in my back seat compared to the other car seat I had. I will say this seat is very heavy duty you can tell by the weight. This seat is very well made, I have had it in my car for about 5 months or so now and it works perfectly. Now I do have a concern when it comes to the chest clip my daughter is 3 and is easily able to slide the chest clip up and down she can maneuver her arms out I wish there were a stopper or something. Other then that the seat is amazing.
