The rear-facing position is widely recognized as the safest in the event of a collision. When that happens, you can opt for a convertible seat from our Radian series. The Radian all-in-one convertible car seat represents optimal safety and excellent value for money.

The best convertible car seat must be durable and able to withstand constant daily use. Diono offers many options, including the seats in the Radian series.

Besides engineering innovation, the Radian’s design includes innovative mechanical engineering. Its unique automotive-grade steel core construction sets it apart, and its strength gives parents additional peace of mind.

When choosing a car seat, comfort is a critical factor, like safety. The Radian series uses ultimate memory foam in each convertible car seat.

Along with the one-handed adjustable 12-position headrest, the child travels safely and well-supported, so they are just as comfortable on long vacation journeys as they are on a short school route.

The Radian series also has the practicalities covered with cupholders and easy-to-clean fabrics.

The value makes it an excellent choice for anyone seeking a sound, peace-of-mind solution for traveling with a child in a vehicle.

You should switch to a booster seat as soon as the child meets all 4 statements below.
-There's a shoulder and lap belt.
-The child is at least 40 lbs.
-The child is at least 5 years old.
-The child can sit properly the entire trip without leaning forward, slouching, etc.

Typically, this is somewhere between the ages of 4 and 7, although children aged 5-6 are still safer in a 5-point harness car seat.

The exact timing depends on the child's weight and height. In general, you can switch when the child is capable of sitting on the booster and is at least four years old, 40 inches tall, or weighs 40 lbs.

The difference is in how the seats transition. All-in-one convertibles are used for newborns and infants and transition from the rear-facing position to a forward-facing position with a harness as the child grows.

Convertible booster seats have a higher weight limit, so they are used for longer. They can transition from a forward-facing harness seat suitable for toddlers and preschoolers to a belt-positioning booster.

For safety reasons, when to switch isn’t decided by the child's age but by its weight and height. Typically, once the child is over 30 lbs. and at least 32 inches, they are switched out of an infant seat and into a convertible. Diono allows children as small as 5 lbs. to fit rear-facing in a convertible, which allows parents to save on transitioning from infant car seats.

Yes, convertible car seats can be used by 4-month-olds, as long as the weight of the child is 5 lbs or greater. There are rear-facing seats designed especially for newborns and babies under one year. What matters most is that the convertible seat is correct for the child’s height and weight and properly aligned with the seatbelt.
