I use the Radian RXT and we are so grateful that it is so narrow, as we have to fit 3 carseats in our vehicle! The material is soft and comfortable and because it is made of steel, it really puts me at ease and reminds me that they are safe in their diono..

    parents love the JMC!

    “My family and I were traveling on vacation, and had an accident after being hit by a semi. Our vehicle did several spins, and rolled several times. My one year old son was seated behind the passenger’s seat, the side of impact. As we were rolling his window broke. Once we came to a complete stop, his seat had not moved. He had NO injuries. He was the only one in the car completely unharmed. The car was totalled. I’m convinced it’s because of the reinforced steel/aluminum frame. I’m forever grateful for how well made this carseat is. Thank God for the friends who purchased it as a shower gift. This carsest saved my baby’s life.”

    I have now had the Diono RXT in Spring print with the angle adjuster for about 6 weeks now. I love this seat I love its low profile sides its 45lbs weight limit and that it can be used with an AA to give it a more upright angle and more front to back space. I found it east to install and adjust. I maybe alone on this but I love the shoulder pads. I would most defiantly recommend this to my friends looking for a seat to last a good couple years. My only cons with the seat is it is quit heavy at 25lbs and its only really good for rf and ff as the booster function is often out grown when the the harness is out grown ff. Other then that a great choice.”

    -Mom22, Silverdale, WA

    We bought this car seat about 5 months ago and it was the best decision! We searched and searched for the perfect car seat that was 1st of all safe, user friendly, long lasting, and stylish. My mom had purchased a different convertible seat for her vehicle for my daughter, but once she saw mine, she returned hers and purchased the same exact one I have. The red is beautiful ❤️ Thank you Diono for giving us the confidence my little girl is safe.
