Amazing carseat!
We have two of these carseats now and absolutely love them. They are slim and provide a lot of room for both the child using the carseat and the person sitting next to the car seat. I love how these carseats feel open and not so enclosed for the child.The car seat itself is very easy to install correctly and the cover is easily removable and reattachable for easy cleaning. The padding is great and it feels really secure and has great stability. Overall great quality.The only thing I wish that was different, is i wish these came with at least one cup holder. These are the only carseats I love to use for forward facing kids!

Diono Radian 3R: A Safe and Space-Saving Car Seat for Long-Term Use
We absolutely love our Diono Radian 3R! It’s been a fantastic car seat for our child, lasting from infancy all the way to booster use. Here’s why it gets 5 stars:Space-Saving Design: This car seat is a dream for tight spaces. Its slim design allows us to fit 3 car seats across our mid-size car, perfect for families with multiple children.Long-Lasting Value: This car seat truly grows with your child. It transitions seamlessly from rear-facing for newborns (up to 50 lbs) to forward-facing (up to 100 lbs) and then to a booster seat (up to 120 lbs). It’s a one-time investment that lasts for years.Comfort & Safety: Our child finds the Radian 3R very comfortable, with breathable fabric and a well-padded design. Plus, Diono’s safety record and features like the steel-reinforced frame give us peace of mind.Easy to Use: Installation with SuperLatch was a breeze, and switching between rear-facing and forward-facing is simple. The harness is easy to adjust and the removable cup holders are a convenient touch.Easy to Clean: The Diono Radian 3R’s machine-washable fabrics make cleaning up spills and messes a breeze.If you’re looking for a convertible car seat that’s safe, space-saving, comfortable, and built to last, the Diono Radian 3R is an excellent choice!

Great for a slimmer car seat
We had a Maxi Cosi car seat, this is MUCH slimmer however seems as secure. The straps are more streamline and easy to use as well. This leaves more room between the front row so my 4 year old has more room for her feet. Highly recommend for a three row car.

Great car seat!
Love the compact size of this carseat. We bought it for my husband’s sedan so we can fit this seat for our 5 year old, a booster for our 8 year old and an infant carseat for our 4 month old in the back seat. It’s still a little snug but it works. My only complaint is that the car seat is supper heavy, but it’s really not that big of a deal. Love the fact that you can fold the seat up as well.

Difficult installation
It was time for my little one to upgrade from the basic infant seat, and I was looking for something that would fit her until she no longer needs a car seat/booster but still needed it to be affordable and in our budget. After looking at several other options, this seemed to fit the bill the best.It’s very sturdy, and baby loves sitting in it. She’s still rear-facing, and loves the extra room she has compared to her old seat.The only complaint was the difficulty we had figuring out how to install it in our vehicle. It took my partner and I both quite a bit of time, and found the manual to be little to no help. Once we finally figured it out, though, it seems very secure and doesn’t wiggle or move around at all, so we do feel confident about baby being safe

Fits Porsche 911 perfectly
Finding a compact car seat to fit my Porsche 911 has been difficult – this one fits perfectly. Kid says itâs comfortable and seems to be really sturdy. I wish is came with cup holders but they are available for an additional purchase. Overall happy with it.

Favorite Car Seat
Canât say enough about this car seat. We are using it in our large SUV as it gives my daughter so much more leg room with it being less bulky. Beware that cup holders are sold separately. It has been great to travel with if you buy their travel backpack. So much less bulky than a regular car seat and the travel bag is amazing quality. We ended up buying one for each of our cars, plus Grandmas.

Fantastic car seat; Do not base decisions on advertising
We live this car seat – itâs slim, itâs heavy duty, and the kids are comfortable in their seats. Weâve put each of ours in a diono since birth and have never had any issues with these seats. The ONLY issue with them isnât 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 weâve 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, Iâd 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, Iâd 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 youâre 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 canât do anything less than sing high praise for diono and Iâd absolutely recommend any one of their seats to another parent.

This seat is great. Very heavy but it’s stable and fits perfectly in the car. Very happy it was only $200

Ocupas ser un Ingeniero Aeronautico o automotriz para Instalarlo. Es demasiado Dificil su instalación. Pero brinda buena protección al BB

We bought these specifically for their narrow size for aeroplane travel with our kids (3, 5).They fold nicely and can sit on top of your luggage. We used a small crank tie to attach it to our carryon as it is awkward and a bit heavy to carry on a long walk through an airport terminal.But it fits nicely in aeroplane seats, they are very quick and easy to install in both cars and planes. The pull strap to secure your child is a lot easier to use than other car seats we have used.These are a bit pricey, but are absolutely worth the cost.
