Top 10 Best High Back Booster Seats On The Market 2021 Reviews
1 Britax Frontier – The Flatback Booster Seat
The Britax Booster Seat, like most of the best high back booster seats, is designed for children in transition, particularly in those fast-growing years between toddlers and big kids. It boasts easy installation and eliminates most of the hassle of rethreading the harness as your child grows. Instead, it is designed to be as easy to use as a seatbelt.
There is one caveat to this ease of use though. Several reviews have pointed out that if you use this booster seat in a vehicle seat that has a concave back on it, the harness will not tighten correctly.
2 Graco Nautilus 65 LX – 3 Phase Booster Seat
Graco is a big name in children’s products. They have years of experience creating products to keep children safe at affordable prices. They manufacture some of the best high back booster seats available.
The Nautilus 65 LX is no exception. It is based around the idea of transitioning your child from 22 pounds to 100 pounds in three phases. Each of these phases is supposed to work with a simple harness adjusting system that shifts from three different positions, without having to rethread everything. In fact, Graco all but guarantees you will not have to rethread this seat ever.
Unfortunately, there seem to always be exceptions to the rule. Sure enough, some reviewers have claimed that they received their booster seat and needed to rethread it immediately. Whether this is refurbished seats being sold as new or simply quality control not keeping up with marketing, it has left some customers disappointed. After all, simplicity is the selling point with this high back booster seat.
3 Graco Affix Youth Booster Seat – For No-Headrest Vehicle Seats
Here is another great Graco product. This seat starts with slightly larger toddlers (40lbs) but will continue to be one of the best high back booster seats for children up to 100lbs.
It allows for easy self-buckling, letting your children learn to buckle themselves into the seat as they grow. The harness is designed to be adjusted in the front, simplifying the transition from smaller to larger children who use this booster seat.
The single problem reviewers have written about the Affix Booster Seat is that it will not work properly in a vehicle seat with a headrest. However, if the headrest is flat and flush with the seat, this high back booster seat may work for you after all.
4 Britax Pioneer Combination Harness – Britax Runner Up
Here is a second version of the Best High Back Booster Seats from Britax. Most customers buy this seat as a secondary version of the Frontier and use it in their secondary vehicle. They do this because it is less expensive than the Frontier and hope to benefit from the company quality at less cost.
Unfortunately, this booster seat is harder to install than the Frontier. Additionally, the harness becomes unable to fully secure your child once they reach 45-50lbs, requiring the use of the seat belt. This booster seat is certainly useable, but it does not compete with the Frontier.
5 Chicco KidFit – Kids Comfort Booster Seat
Chicco is well known for creating plush and comfortable car seats, ranking them among the Best High Back Booster Seats. The KidFit is a prime example of this ingenuity at work.
The double foam padding provides a contoured design that maximizes comfort for your child. There are 10 different positions you can arrange it into as your toddler grows. Also, parents love how easy it is to install and use. This is a very lightweight and popular booster seat.
However, there is one small complaint some reviews make. The plastic piece on the side of the booster seat does not always hold the seat belt well, making it difficult to secure.
6 Diono Monterey XT – The Booster for Big Kids
Diono makes one of the best high back booster seats for bigger bodied kids. Kids that fit the ranges of 40 to 120lbs can come in a variety of shapes and sizes and sometimes booster seats run too narrow for comfort.
The Monterey XT provides a wider base for your child. It is comfortable and affordable and will safely transition your child as they grow from 38 to 63 inches tall. The only downside to this booster seat is that slimmer children have a much more difficult time fitting in it securely.
7 Evenflo Chase Harnessed Booster – Harness to Belt Booster
Evenflo is another company that creates quality car seats and some of the best high back booster seats on the market. The Evenflo Chase is no exception.
This combination booster car seat fits children from 22 to 110lbs and transitions them from a five-point harnessed seat to a belt-positioned seat as they grow. Because of this transition, you can expect to get several years of use from this booster seat.
However, since this is designed as a transitional car seat, it does not recline as well as seats meant for younger children.
8 Graco Highback Turbobooster – Layered Design
Here is the second Graco car seat to make it on the Best High Back Booster Seats list. Like the Diono booster seat, this design runs a little wide and starts with 30lbs kids instead of 20lbs like many of the other car seats. The inside width is 16.5 inches, which may be too wide for slimmer children.
One of the key components, according to reviewers of this booster seat, is that it seems to have layers. It has a layered headrest. Additionally, the back seems to act as a layer as well. The seat back is attached to the bottom, but not to the car seat itself, so it can be easily removed as you graduate your child up from a toddler in a harnessed car seat to a big kid, depending more on the seat belt.
9 Evenflo Big Kid AMP – Removable Back Transition Seat
This is the second Evenflo booster seat on the list of Best High Back Booster Seats. This is another example of a transition car seat with a removable back.
In addition to the removable back, this seat has an easy one-hand adjustment that moves the seat between six different positions to help grow right along with your child. The Big Kid AMP also comes with two cup holders for drinks and is padded with an energy absorbing liner keeps your child cool and comfortable.
Among reviewers, the only complaint has been that some bigger kids appear less secure in the seat and it could benefit from having a latch to keep them secured better.
10 Cosco Finale DX – Economy Booster
Cosco is another leading brand of child safety accessories. The Finale DX is another version of the five-point harness that transitions to booster seat model. Cosco’s version focuses on removable and easy-to-clean seat pads and cupholder accessories.
This seat meets all the federal ASTM and JPMA safety standards. However, some reviewers have noted that the plastic parts of this seat are less durable than some of the competitor booster seats. That said, there are enough savings in overall value to include this on our list of Best High Back Booster Seats.
Best High Back Booster Seats Buyer’s Guide
The number one concern with the best high back booster seats is safety. All of these booster seats have been tested and most have reviewers who have shared a testimony of their helpfulness in the case of an accident. If the seat could not perform its most basic function, it would not be on this list. However, some of the safety-related functions go beyond government testing and may depend upon certain aspects of your child as well.
For instance, children of different sizes will be kept more secure in some seats more than others.
All of these seats are transitional seats. This means they cover a range of height and weight capacity for your child. However, some have lower or higher ranges than others.
On the lower, lighter end, the Graco Nautilus, the Evenflo Chase, and the Chicco Kidfit all are safe for children just over 20lbs. These seats all will stay with your child up to about 100lbs.
For kids who may have larger bodies (even if they are not heavier), there are several good options as well. The Diono Monterey XT is made for bigger kids. You can also check out the Evenflo Big Kid AMP and Graco Highback Turbobooster. Any of these should be able to accommodate bigger kids, and several of them start out at a 40lb weight capacity and go up above 100lbs.
If safety is the number one concern of parents, ease of use is easily number two. it comes in two kinds of categories: installation and transitioning between kid sizes.
As far as installation goes, most of these seats are fairly easy to install in ideal vehicle seat conditions. That last phrase, “ideal vehicle seat conditions” is what makes all the difference.
In short, most of the seats made for bigger kids tend to fit in a wider variety of vehicle seats. Evenflo, as a company, probably does the best out of this top ten best high back booster seats list. The Cosco and Chicco seats tend to fit in most places as well. The Cosco is actually designed to fit three in a back seat. Additionally, the Diono seems to work in most conditions.
The Graco and Britax both have complaints about being difficult to install or not fitting in vehicles where the seat back has any kind of curve in it. All of their models on this list have issues from the reviewers regarding the trouble they have fitting in certain vehicle seats.
Comfort is probably the child’s first priority, but it often fits further down the list of priorities for parents. If you are looking for comfort, Chicco is the brand to check.
Chicco has a reputation for developing plush car seats, and the KidFit lives up to that expectation. If you want to look elsewhere among the best high back booster seats as well, the Evenflo seats are padded with energy absorbing foam liners that help keep your child cool in the seat.
