Diono Rainier

Diono Rainier provides extended foward-facing and rear-facing capabilities, as research has shown that children are safer in the event of a crash when their car seats are rear-facing. Children can comfortably rear-face in this car seat from 5 to 50 lbs. When kids are ready to forward-face the Rainier, it is approved for children weighing 20 to 90 lbs. in 5-point harness mode. As of the date of this publication, this is the highest forward-facing capacity of any car seat with a 5-point harness. Additionally, it converts to a booster for children between 50 and 120 lbs. or up to 57″ in height.

This Diono Rainier seat comes with a body support pillow (to be used for infants and toddlers) and a head support pillow (to be used for infants). However, it is important to note that parent can use this seat with their newborn as long as their baby is at least 5 pounds. If you are on a budget, purchasing this seat to begin using at birth will save you money in the long run, since it would probably be the only car seat your child would ever need thanks to its industry-leading 12 year product life (from the date of purchase).

Diono Rainier Review

What distinguish the Diono Rainier from every other car seat is that they have the largest forward-facing capacity of any 5-point harness car seat currently sold in the United States at 20-90 pounds with up to 57″ of height. Each transition in child seats signifies a decrease in safety (e.g., rear-facing is safer than forward-facing, which is safer than a booster position, which is safer than simply using a seat belt); the longer you can keep a child forward-facing in a harness, the better.

Something else that’s neat about the Rainier is that it’s one of only a handful of seats in the United States that can currently be tethered while rear-facing as well as while forward-facing. It isn’t required to rear-face tether, but rear-facing tethering does have its advantages. Diono Rainier is also simply an easier seat to install than most, due to its narrow base width of 17 inches. That means it’s actually possible to install 3 across in a number of mid-sized vehicles.

As with any product there are always positive and negative, below is what customer like and dislike about this booster car seat we found on Diono Rainier Review online.

Pro: Nice looking and Comfortable, Easy To Install, Sturdy, Safety, Narrow so will fit 3 across, Long use life.

Cons: Heavy, The Price is not Cheap.

Review from user that purchase this Diono Rainier: “We were in an accident not too long ago and had a diono rainier. Our kid didn’t suffer at all. We swear by diono and with the insurance money bought a higher model. My daughter is tall and this seat really adjusts well to her and still doesn’t take up as much room as the other bulky models. Love it and it’s 12 year lifespan! ” (Read More Reviews…..)
