The problem with most high back booster seats is that they tend to be expensive and outside the budget of many people. This is not an issue with the Evenflo Big Kid 31911718. It is one of the best high back booster seats that you can get based on price alone.

The entire seat is covered with energy-absorbing foam that not only provides comfort but also protects the user during an impact. The headrest is also plush and comfy. Since this is a 2-in-1 seat, you can quickly change it from a high back booster design to a backless seat.

Furthermore, it contains 2 handy elastic cup holders to the sides. If a liquid spill on the seat covers, they can easily be removed and are machine washable. There are also 2 hand rests to the sides for maximum comfort.

The only issues we take with it is that the build quality is not the best we have seen. For the price, it is understandable. Also, the bottom lumbar padding is not very thick and could have been better.

Notes: This seat is only intended for children that are at least 40 inches in height. If not, it will be uncomfortable and cannot be used.

How to Buy the Best High Back Booster Seat

How To Buy The Best High Back Booster Seat

1. Weight Capacity

One of the most important factors to consider when purchasing a high back booster seat is weight capacity. It is essentially how much weight the seat can carry and still comply with the safety standards set by the manufacturer.

Most top-rated high back booster seats will have a weight capacity range of at least from 30 lbs to 100 lbs. Additionally, keep in mind that the weight capacity of a high back booster varies depending on the age and height of the child.

There will basically be 2 weight capacities ranges to consider. Remember that the high back booster seat can be rearranged to be used in a high back mode and backless booster mode. Each has different weight capacities.

2. Solid Frame

Most high back booster seats have a solid metal frame that gives it its shape and durability during an impact.

This solid metal frame is then coated with a thick layer of plastic, which in turn has a soft foam on top for comfort.

So, if you want to get a high back booster seat that can resist any type of impact, then you must also consider the frame inside.

Moreover, a model that comes with a metal frame will also result in a seat that is more durable and last longer.

3. Adjustable Back and Headrest

By having the possibility to adjust the back and headrest of the high back booster, you make it more flexible and comfortable to your child.

Additionally, a model that comes with an adjustable headdress will be safer because it allows you to make specific adjustments based on the height of your child.

Not all models have an adjustable back and headrest, so we recommend firsthand that you check if your model of choice has this functionality. It should be easy to adjust, and you don't need special tools to do so.

4. Side Protection

In case of an impact to the side of the vehicle, it is important that your high back booster seat is protected. Ensure that the model has reinforcement to the side of the seat for additional protection.

It could be anything from a metal frame protecting the interior of the sides or soft padding and foam reinforcements added by the manufacturer.

5. Accessible Harness Adjuster

Most high back booster seats can be installed in 2 modes. A backless booster seat mode and a high back seat mode.

Whenever you change between those 2 modes, you do so by snapping or releasing a harness on the high back booster seat.

So, if you frequently change the mode of your booster seat, then you must make sure that your chosen model has an accessible and easy to use harness adjuster.

6. Seat Belt Guides

The seatbelt remains the best safety accessory to use for your child in a car. Therefore, you must ensure that the seatbelt is easily accessible despite having a high back booster seat installed.

Check if the manufacturer makes any provision for passing the seatbelt through seatbelt guides. The high back booster seat must never get in the way or make it difficult for you to harness your child with the seatbelt.

7. Easy to Install

Check if the manufacturer makes any mention on how easy their high back booster seat is to install. You should be able to securely install or remove the seat in a matter of minutes, if not seconds.

More importantly, the seat much comes with an instructions manual that will show you exactly how to do it. This is important, especially if you have never installed a high back booster seat in your vehicle before.
