Diono – 3 Across Challenge – Car Seat Review & Giveaway

With baby number three just a couple of months away from making her debut, it was time we had the car seat talk. We recently purchased an SUV to accommodate our growing family and now needed to decide where the kids and their car seats would go. Our SUV can comfortably seat 7, with the third row up, but I was (and am!) extremely hesitant to put Adam in the third row all by himself. In my mind, an ideal solution would be: Adam and Lucas in the middle row, one behind the passenger seat and one in the middle, and baby girl rear facing behind the driver seat.

That’s where the Diono RadianRXT comes in. The RXT is advertised as having the ability to fit three across while offering more shoulder room than any other car seat. Sounded like a winner to me, but of course, I am a skeptic and a “won’t believe it until I see it” mama so I had to put it to the test myself!

With our current set up, there is NO way we could fit three car seats across, Lucas’ car seat is extremely bulky. Diono generously sent us the car seats we needed in order to help with our “three across” challenge. A little bit about the RadianRXT:

  • Rear-facing: 5-45 lbs
  • Forward-facing: 20-80 lbs (and up to 57″) in 5-pt harness
  • Booster to 120 lbs
  • Energy-absorbing EPS foam panels on all sides
  • Memory foam padding for superior comfort
  • 5 shoulder and 3 buckle positions for custom fit
  • Expandable sides and longer seat bottom for leg support and comfort
  • 12 height positions for adjustable head support
  • 2 recline positions in forward-facing mode
  • Folds flat for travel and storage
  • 10 year life
  • Available in 7 fun colors

The RadianRXT is very easy to install, by SuperLATCH or seat belt. The RadianRXT is NCAP crash tested, the industry benchmark for verifying child seat performance in severe accident conditions, and the only car seat rated for LATCH use with a child up to 80 pounds. Needless to say, I feel extremely confident that my babies (newborn through 5 years) are safe in this seat.

BUT, did it live up to the three across promise?

Adam and Lucas in their RadianRXTs, three across, with plenty of room to call their own.

Hopefully Lucas won’t pick on his sister ;) We *may* place Adam in the middle seat, I imagine he’ll be a big help in comforting both of his siblings while in the car.

The 3 RadianRXTs just fit in our car. The seats, and kids, aren’t going to be squished. The only problem? We probably won’t be placing the cup holders onto the seats because it doesn’t seem there will be sufficient room and that could = a lot of messes! When the time comes to put the rear-facing seat forward-facing, I have no doubts that we could keep the same arrangement and the kids will all fit in the middle row.


You can purchase the Diono RadianRXT for $299.95, on sale!

    I have heard a lot of good things about this car seat & would love to try it out. Thanks!

  2. I’d love to have this for my car since we have two cars and only one carseat

  3. I have heard that it is an awesome car seat! We have twins so it would be perfect for us! I also like that it is narrow enough for smaller vehicles!!

  4. Jennifer says:

    That’s a great solution for some with $900+ to spend on carseats but I think that is a lot of money for the average person. I know for myself, I can’t afford that. Unfortunately, we are going to need to figure out how to make do using our 2nd and 3rd rows.
