5.0 out of 5 stars Kept my 8 year old safe in a head on collision 💖
By EHN,RN on February 27, 2020
Bought two of these to replace our old ones after a head on collision with a drunk driver. I am endlessly thankful for this seat’s ability to keep my eight year old in a five point for so long. I feel sure he would have been injured if he had been in a shoulder/lap belt rather than restrained in a harness. He wasn’t even sore!! Yes, these seats are heavy as hell but well worth the muscle.
Thank you Diono for an excellent product!!

5.0 out of 5 stars Beautiful slick design, just fits in our Kia Soul
By Sven5000 on March 10, 2019
We were dreading having to get a convertible car seat that takes up a ton of room in our compact 2015 Kia Soul. My research pointed to the Diono Radian 3RXT or the Graco Slimfit as the best choices. I chose this one for its slick and simple design, removable cover, and narrow width.

Our 29" tall one year old seems quite comfortable in it. It gives me enough room to sit by her side as well. In its rear facing position, the seat does take up a lot of room front to back. The $10 angle adjuster is a must. When we first installed it without, it would definitely poke into the back of the front seats even more. With the adjuster, it definitely touches the shoulder of the front seats. I don't know if there are better options out there for rear facing depth but if you have a smaller car, I would not recommend this seat. As a forward facing seat, it takes up very minimal room and I would highly recommend for any sized car.

During our first outing in this seat, my 1 year old got car sick and vomited, so we had to remove the cover to wash and set it up all over. The cover did not change its shape and fit right back on without a problem. Putting it back together was also pretty self explanatory, though there are some videos online you could watch for help. The headrest adjuster is a little tough to move up and down. While the mechanism is quite simple, you really have to push it to move.

This seat is quite heavy at around 28 lbs, so I would not recommend this for anyone who has to shuttle this back and forth between two cars. This seat is FAA approved as well, though it may be too heavy to lug around the airport. I plan on purchasing a used FAA approved travel car seat for future flights.
