In fact, this car seat can support children in the rear-facing position until they reach the weight of 50lbs or until they turn eight years old. It is worth noting that Diono Rainier® 2AX is not equipped with the booster option and that you can only use its built-in belt system.

Diono Rainier® 2AXT

diono rainier 2axt black The Booster capacity and the head support system that allows you to choose from twelve different positions are the most noticeable differences between the two Rainier models. The addition of the Booster feature extends that car seat’s weight capacity to 120lbs which ensures that you won’t have to search for a replacement as your child grows. In addition, you can choose from a variety of covers that are made from high-quality fabrics in case you don’t like the seat’s original design.

Here are the Diono Rainier® 2AXT most important features:

  • Adjustable headrest with 12 available positions
  • This seat has the Booster capacity and can support children that weigh up to 120lbs

Diono Rainier® 2AXT Prestige

diono prestige The only difference between the Diono Rainier® 2AXT and Diono Rainier® 2AXT Prestige models is the material used for the finish as all other features are identical. The design of the car seats from the Prestige series is inspired by the interiors of classic cars, and you can choose between Tan leather, Black Red leather, and Beige Oyster leather options. Also, the manufacturer claims that the models from their Prestige line become better over time as patina gives them a stylish look that matches a vehicle’s upholstery. Moreover, you will get a two-year warranty if you opt for the Diono Rainier® 2AXT Prestige car seat.

The installation process

Installing a child safety car seat may be trickier than it initially seems, because the manual may not contain all the information you need to install a Diono Rainier car seat in your vehicle. Making sure that the seat is properly installed can be challenging even if you follow the manual closely because it is difficult to prevent the seat belt from twisting. The paths where the belt should go are clearly visible but they are located near the base which is the reason why it can be difficult to reach them. In most cases, the ease of installation depends on how compatible your vehicle is with the Diono Rainier model you’ve selected. Furthermore, you must consider the size of the model you want to purchase since the height of the seated torso ranges from 8.27 to 17’’. Keep in mind that you may have to move the passenger seats in order to place this car seat in the rear facing position. However, all of the models from the Rainier series are narrow, which means that you won’t have trouble finding space for it in your car’s backseat. The tether strap becomes more important once you start using the Diono Rainier’s Booster option, and you must make sure that it is secure before you allow your child to sit in the car seat. Unlike most safety car seats, Diono Rainier models enable you to use the tether to provide additional safety while the seat is in the rear facing position.

The cost of Diono Rainier car seat models

Which of the Diono Rainier models you are going to choose depends on your budget, and you should be prepared to spend at least $300 if you want to get a car seat from this manufacturer. The Diono Rainier® 2AX car seat can be purchased for $299 which makes this model the least expensive option from the Diono’s Rainier series. A Diono Rainier® 2AXT seat can cost between $249.99 and $399.99 Although the models from this series may seem expensive, their Booster feature enables you to use them for up to ten years. In addition, you’ll get a two-year warranty if you opt for any of the models from the Rainier series. The Diono Rainier® 2AXT Prestige car seats are the most expensive since you have to spend $2.250.00 if you want to acquire a Tan Leather, Black Red Leather, or Beiger Oyster Leather model.

FAQs About Diono Rainier car seats

Is it difficult to clean a Diono Rainier car seat?

No, it isn’t, as you can clean the harness strap or the memory foam using cold water and clean cloth. Keep in mind that you will have to replace the harness strap if you expose it to any type of liquid for a long period of time.

You can continue using any of the car seats from the Rainier series until your child reaches the weight of 65lbs or 120lbs or until it outgrows the seat’s height limit of 57’’.

Can I install a Diono Rainier car seat on my own?

Yes, but the installation process can be difficult until you get used to it, which is why you should have assistance during the first installation of the seat.

The Verdict: Are Diono Rainier car seats worth investing in?

The idea behind all-in-one safety seats is to provide you with a safe and comfortable seat your child can keep using as it keeps growing.
