Perfect for multiple kids in a smaller vehicle
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.

Diono Radian 3R - A Game-Changer in Car Seat Comfort and Safety!
The Diono Radian 3R 3-in-1 Convertible Car Seat has proven to be an absolute game-changer for our family, and my son absolutely loves it!The versatility of this car seat is outstanding – from rear-facing to forward-facing, it's designed to accommodate different stages of a child's growth. The 10-year lifespan is a fantastic feature, providing peace of mind knowing that it will last through various developmental milestones.My son finds the seat incredibly comfortable, and the plush padding adds an extra layer of coziness. The reinforced steel frame gives a sense of security, and the installation process was surprisingly straightforward, thanks to the clear instructions provided.What sets the Diono Radian 3R apart is its slim design, making it a perfect fit even in compact cars without compromising safety. The adjustable headrest and harness system ensure a snug and secure fit as my son continues to grow.As a parent, I appreciate the ease of cleaning – the fabric is removable and machine washable, a lifesaver for those inevitable spills and messes.If you're in search of a convertible car seat that prioritizes both comfort and safety, the Diono Radian 3R is an excellent choice. It has made our car journeys much more enjoyable for my son, and as a parent, I couldn't be happier with this purchase! 🚗👶🌟 #DionoRadian3R #ConvertibleCarSeat #SafetyFirst

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.Pro’s: slim, sturdy, easy for our kids to get into themselves, latch system is easy/works well. Good customer service from Diono. Our first one didn’t 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. Wasn’t an issue in the Camry.No cupholders- fine, since that wouldn’t 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!

My daughter is 42inches, 36lbs- 5 years old pictured here.We bought this car seat with the idea that i wanted a slim durable seat that my daughter could grow in to and have for a long period of time.Pros:• Narrow design, great for tight spaces• Comfortable without the need for extra padding• Minimalistic but feels very secure• Steel frame provides added safetyCons:• Quite heavy, not ideal for travel• Tall and wide when rear-facing, limits front seat adjustment (not pictured here)• Adjusting the shoulder height requires uninstalling the seat, which is inconvenient• Not versatile for use with multiple kids due to the need for frequent rethreading of the harnessOverall, it’s a solid choice for safety and comfort but better suited for a dedicated setup rather than frequent switching or travel.

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."

Amazing Carseat
The Diono Radian 3R car seat is a fantastic investment! It offers exceptional safety, comfort, and longevity. With its versatile design and easy installation, it grows with your child. Plus, the removable covers make cleanup a breeze. Highly recommend!It is kinda heavy to lug around so it’s best to not move it much.
