Great seat for smaller back seats.

I got this for a better fit in my Jeep Gladiator. It made a huge difference in giving my toddler more leg room, and it will easily fit 3 across as advertised.

Excellent safety features for a tall 7-year old boy. Almost the only model on the market that fits.

I would give this 4.5 stars if I could. It is one of the only seats that will fit my tall 7-year old boy that has a multi-point harness. It also has enhanced support for the head and neck (again, one of the only such models on the market that will fit a tall 7-year old).I say 4.5 instead of 5 because at least in a Tesla Model Y, it is impossible to get this seat 100% tight and immobile. That's a bit annoying and different from the baby / toddler seat I had before. However, compared to the standard issue "booster seat" that my boy could legally use, I am convinced that this provides much better protection even with a bit of "wiggle."

Safe, affordable, & comfort all in one!!!

Great car seat! It’s 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! It’s 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 won’t 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, it’s 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 it’s very comfortable which is a huge bonus! Definitely a must buy car seat!!!

Good quality, compact design.

Very solid seat. A bit on heavier side. Shallow back design allows for more leg room if forward-facing direction chosen.

Great for 3 across

Diono products have been a life saver for fitting my 3 kids in one row. I have 3 rows, but prefer having my kids farther from the rear of the vehicle in the case of a collision, and I also like having the trunk space.

Make sure that you have a vehicle that has all safety hooks for rear and front face use

The car seat is nice however with certain vehicles using the top tether hook for safety is not an option while using in rear facing. No instructions came in the box so I had to google the manual. According to the manual the top tether safety latch is supposed to be used when in rear facing. It is rather big still for my back seat even though it is a slim fit. Not much when adjusting it is pretty basic. I have not cleaned it yet since I just got it yesterday. My baby seems to be comfortable to n it but when he falls asleep I worry with the way his head slumps over.

3 in a row with infant seat

I have a 2022 kia Sorrento and I’m about to be a mom of 3under 4 and I really wanted all my kids in the middle row but I was able to with the Graco slim fits and the infant car seat as while but it fits great with a little room to spare to!
