  • Excellent safety features for a tall 7-year old boy. Almost the only model on the market that fits.
Style: Radian 3R SafePlus Fits 3 Across Color: Black Jet
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." ... show more

  • Safe, affordable, & comfort all in one!!!
Style: Radian 3R SafePlus Fits 3 Across Color: Black Jet
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!!! ... show more

  • Great for 3 across
Style: Radian 3R Fits 3 Across Color: Black Jet
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.

  • 3 in a row with infant seat

  • Slimmest carseat out there!
Style: Radian 3R Fits 3 Across Color: Black Jet
Able to fit 2 dionos and a doona into my toyota corolla. Only carseat with such a slimfit design. Not the most comfortable headrest but the slim design is worth it.

  • Make sure that you have a vehicle that has all safety hooks for rear and front face use
Style: Radian 3R Fits 3 Across Color: Black Jet
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. ... show more

  • Perfect for multiple kids in a smaller vehicle
Style: Radian 3R Fits 3 Across Color: Black Jet
Easy to install, fits 3 across in our mid-size suv, very comfortable for long rides for our kids, a little on the heavy side but that comes with a durable car seat. Colors are what we ordered. Easy to clean. Easy to adjust straps.
