Rainier Convertible Plus Booster Review (Diono)

Rainier Convertible Plus Booster
What It Is

The Rainier Convertible Plus Booster from Diono is a convertible car seat that can be used as a rear-facing seat for infants, a forward-facing seat for toddlers, as well as a booster for a child up to 120 pounds. A two-piece infant body pillow insert provides comfort and extra support for your rear-facing infant. It features a steel frame that is sturdy and solid to keep your child safe, while also space saving. The seat itself is also spacious enough to grow with your child.

The Rainier meets the stringent European standards of safety, especially in regard to side impact with its extra deep sidewalls and 12-point height adjustable head support. It also uses the Latch System to click right into your car for easy installation. However, if your car does not accommodate the rigid Latch System, the car seat can still be rigged through the seat belts.

Why Is It Useful?

While this is a higher price point car seat, it is built to last. We like that it grows with your child, which adds to the value.

Who It’s For

The Diono Rainier Convertible Plus Booster is for use from birth up to 120 pounds.

What To Be Aware Of

In rear-facing position, it accommodates children 5-50 pounds. In forward-facing position, it accommodates children 20-90 pounds. And in booster mode, it holds 50-120 pounds.

This car seat is fairly heavy at 28 pounds.
