The radian 3QXT by Diono is another all-in-one car seat, accommodating babies weighing between 4 lb and 120 lb. The rear position can hold a child of up to 50 lb, the weight of an average 4-year-old, increasing the child’s safety.
The car seat comes in five different colors. It has a slim design, which makes it possible to fit in most vehicles. The frame is steel, and impact-absorbing foam surrounds it.
The Peg Perego Primo Viaggio car seat is suitable for babies from 5–45 lb. As with the previous examples, the attaching system of this car seat uses a fixed base and a carrier, which is easy to click in and out and is suitable for use on a stroller.
This car seat is rear facing with five available positions for the headrest. The harness connects at three points and has soft cushioning on the straps.
The Britax B-Safe 35 is similar in many ways to the Chicco KeyFit 30. There is more leeway for taller babies, but the width is narrower. The maximum user weight is 35 lb, and the maximum standing height is 32 inches.
As with the Chicco KeyFit 30, this model has a clip-in-and-clip-out function, with a fixed base in the car. People can adapt the carrier to comply with different stroller bases when they use it outside of the car.
The Britax B-Safe 35 has an adjustable shoulder harness, making it suitable for babies of different sizes.
