Designed for families with discerning taste, the Diono Radian® 3QXT+ all-in-one car seat offers first-class travel from birth to booster, cocooning children in safety and comfort as they grow. The 3QXT+ meets families’ needs for the luxe lifestyle with premium fabrics, adjustable calf support, and layers of memory foam cushioning and head support to keep little passengers safe and comfortable from the newborn stage and rear-facing for longer, to forward-facing and through the booster years.
“They’ve put a lot of thought into the safety features and design.”
“The newborn and infant padding is quite extensive. There are 4 different accessory pads that can be used based on your newborns height and weight. They all feel very cozy and supportive. When the padding is removed, the toddler setting is still very comfortable and has memory foam padding on the seat.”
“The calf support is adjustable and makes long rides in the car more comfortable without pinching a nerve or causing legs to fall asleep. The head rest has 12 different positions and gets very tall for the booster setting.”
“There are lots of accessories and you should read all the instructions and the manual so you know what each one does. I watched the instructional videos. For example, there is a “safe stop” harness accessory that I would have never thought to use if I didn’t do a deep dive into the instructions. For children less than 40 pounds, it’s necessary to install with a forward facing seat. Take your time and read and learn about every feature.”
“I like how safety-focused the design of the car seat is, and that you can use this from newborn to booster.”
