    What car are they in, in the picture? I’m having a hard time finding 3 that will fit in my Suburban.

    • Mari

      It is one of the narrowest carseats out there, but you prolly want to measure

    • animity

      This will totally fit your suburban. We fit three across in our minivan.

    • momof7

      They will fit!

    I’ve heard good things about this car seat having a steel frame even though I have the graco4ever and like it.

    • Collin (Mrs. Hip)

      Thanks for sharing Candace!

    I love our diono, it is heavy if you have to move it alot, but its good if you have tall/heavy lil ones. My daughter is very tall and out grew her carry seat with 5 months, we got the diono because its good for big kids, now 4 years later its still going strong as a 5 point booster (you can use car belt too for booster). Its a good all in one seat from backwards to booster.

    • Collin (Mrs. Hip)

      Good to know how well it has worked for your daughter over the years Mari! Thanks so much for sharing your experience!

    We love our Diono! Very strong!

    • Collin (Mrs. Hip)

      Great to hear how durable it is Marie! Thanks for the feedback!

    We have 4 of these and love them!! This is one of the only car seats that you can fit three across the backseat. They are heavy but we still take them when we travel and they are great for tall kids.

    • Collin (Mrs. Hip)

      How cool! Thanks for the helpful review Julie!

  6. J. Nguyen

    Such a great price! I had already gone and bought the Graco headwise which is 18.5″ across but I kind of wish I waited because the diono is the most narrow at 17″! I think you guys should definitely make a mention of it in the post that this is THE convertible carseat to get to fit three across in most cars.

    • Collin (Mrs. Hip)

      Thanks for the feedback! We do have that listed at the very bottom of the post! 😉

    These are amazing! They also last 10 years before expiring. Others only last 5. Mine is also FAA approved. Fits great in airplane seats.

    • Collin (Mrs. Hip)

      Sweet! Thanks for the helpful review Keri! Good to know!

  8. Melanie

    I’m very pleased with the quality of our Radian. This is an awesome price!

    • Collin (Mrs. Hip)

      So glad you have been pleased with yours! Thanks for sharing!

  9. momof7

    We love our diono radian rxt! So squishy and nice.

    • Collin (Mrs. Hip)

      Awesome!

    Thank you so much! We have the Rainer for my almost 4 year old. We love that she is still able to rear face, as the weight limit for rear facing is 45 lbs. Just ordered the Radian for my 2 month old for when he outgrows his infant seat (which I’m sure will be very soon). Thanks again!

    • Collin (Mrs. Hip)

      You are so welcome!

    Check out Car Seats for the Littles or Car Seat Lady – if you put in your car it will list all the models and arrangements that will fit 3-across. It’s a great resource.

    • Collin (Mrs. Hip)

      Thanks for the helpful tip!

  12. Vanessa

    We love our Diono Radian. We also have a Maxi Cosi and the Diono is our favorite hands down. Super comfy, super safe, easy to get the harness on and off, narrow… I just love it.

    • Collin (Mrs. Hip)

      Thanks for the great feedback Vanessa! We sure do appreciate it!

  13. Tygre

    This is the only seat that would fit in my Mini Cooper convertible, and yes fantastic. I have various britax seats in the other car and this one has held up much better. Highly recommend.

    • Collin (Mrs. Hip)

      Great to hear how well it has held up! Thanks for sharing!

    These are great car seats and well worth the price!
