    • Diono Radian 3R - A Game-Changer in Car Seat Comfort and Safety!
Color: Red Cherry Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
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 ... show more

    • Almost returned it, Diono Support is great!
Color: Gray Slate Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
Review Image by T. Brink T. Brink
We chose this seat for our toddler since it is approved for airline use. This is also our second car seat so we can minimize the shuffling that we kept doing with the existing seat. This Radian is a very solid seat. It takes up less room than our other seat, but is noticeably heavier. Our toddler loves the seat and loves to say Diono. When we first received it, I thought it was missing the harness pads so I was going to return it to Amazon, but Amazon suggested contacting Diono support first. I got on chat with Diono and told them I was missing parts, specifically the pads. She was very courteous and quickly sent me the attached photo, asking me to fold the seat closed again and look in the cavity in the photo. Sure enough, the pads were tucked up in that cavity, still in their bag. Support was quick and pleasant, so I felt confident in keeping the seat now. This seat is not as easy to get attached snug in the car as our other seat, but it is still a well made seat for our toddler. ... show more

    • Simple, Sleek, Travel Friendly
Color: Black Jet Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
We own 4 of these car seats and have been extremely pleased with them! They keep our car looking sleek while providing adequate space in the backseat for our littles. Most car seats turn backseats into a claustrophobic’s nightmare, but not these! They also travel well (although their sturdy frame makes them a bit heavier). We throw one under our stroller and one strapped to a roller suitcase handle to transport them the short distance to airport baggage checks. Highly recommend and our toddler loves them! ... show more

    • Fantastic car seat; Do not base decisions on advertising
Color: Red Cherry Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
We live this car seat - it’s slim, it’s heavy duty, and the kids are comfortable in their seats. We’ve put each of ours in a diono since birth and have never had any issues with these seats. The ONLY issue with them isn’t even in the seats themselves but the advertising. This product page says it supports booster mode for 40 lbs and more, but the instruction manual (and that of every diono we’ve ever owned) actually says to move to booster mode, a child must be at least 50 lbs (for high back). IF you are thinking about purchasing this seat for the lower weight requirement listed, I’d urge you not to purchase this product; however, if your primary concern is the utmost safety and taking conservative precautions to protect your child at every stage in life, I’d HIGHLY recommend ANY diono product UNLESS you have lap only belts (which diono has transparently admitted their seats would not likely be the safest option for). Whether you’re still searching for a high quality seat or a seasoned parent doing research on the next step, I STRONGLY encourage you to read the manuals for these seats before buying or taking the next step AND reading any FAQs or safety notices that have recently been released by diono themselves. Outside of all that, I still can’t do anything less than sing high praise for diono and I’d absolutely recommend any one of their seats to another parent. ... show more

    • I like it but it's heavy and tricky to install
Color: Red Cherry Style: Radian 3R Fits 3 Across Pattern Name: Car Seat
I got this for my youngest who sits in the middle with booster seats on each side for her brothers. It is narrower than the one it replaces and I really like the red color and design. It looks like a high quality car seat and feels premium. It looks great and fits great in my Range Rover Velar. Overall, I like it but there are a few things to consider: PROS 1. Great looking design 2. Premium feel 3. Easy for my 4-year-old daughter to buckler herself 4. Narrow 5. Comfortable for my daughter CONS 1. It's VERY heavy. If you have to take this seat out from time to time, that might be a concern. This is for my car but my wife would never go for a seat this heavy. It seems like it weighs twice as much as the older Maxi Cosi seat it replaces. If the weight of the seat is a concern, avoid this one. 2. There is nothing intuitive about installing this thing. I had to watch a YouTube video just to find the installation instructions. I'm not kidding - they are hidden in the back fabric and housing. Once you have the instructions, they are not much help. This illustrations are professionally drawn but hard to understand. Even getting the various straps out of the back plastic housings is tricky. ... show more
