Graco TurboBooster Highback Booster Review 2026 — What 1,648 Parents Say
The TurboBooster is the seat you buy when the harness years end. It does not strap your child in — it lifts them up so the car’s own seat belt crosses the shoulder and hips where it should, then converts to a backless cushion when they outgrow the back. At $110.99 on Amazon.ca it is one of the most-bought booster seats in Canada, and across 1,648 verified reviews it holds a 4.6 / 5.
Parents reported it is light, genuinely easy to move between cars, and comfortable enough that kids stop complaining about it. They also reported one thing the product page does not lead with, and it changes how you live with this seat day to day.
A strong, affordable belt-positioning booster for a 4-to-10-year-old, and an easy grandparent-car or second-car seat because it moves in seconds. The catch is structural: it installs with the vehicle belt only, so when no child is in it, it is not attached to anything. Buyers who came from a harnessed seat also found it noticeably lighter-built. Buy it for the job it does; do not expect it to feel like the seat it replaced.

What is it?
It is a belt-positioning booster, not a harnessed car seat. There is no 5-point harness: the seat raises your child and its open-loop belt guides route your vehicle’s own lap and shoulder belt across the strong parts of their body. Graco rates it for 4 to 10 years, 18–45 kg (40–100 lb), up to 144 cm, and it is crash tested to meet or exceed the Canadian CMVSS 213.2 standard.
The 2-in-1 part is real value: the back comes off, so the same purchase covers the highback years and then the backless-cushion years. It weighs about 4.2 kg, which is why it keeps turning up in reviews as the seat that lives in a grandparent’s car.
Who it’s for
- Age: 4–10 years, and only once your child has genuinely outgrown their harnessed seat.
- Size: 18–45 kg (40–100 lb) and up to 144 cm (57 in).
- Best for: a second car, a carpool, or a grandparent who needs to move it constantly.
- Not for: a child still within the limits of a 5-point harness — a harness is the more protective stage, and moving up early gives that away.
What 1,648 parents actually said
Across 1,648 reviews the TurboBooster averages 4.6 / 5, with 92% of parents at 4 or 5 stars. The praise is remarkably consistent — light, easy, comfortable, and cheap enough to buy a second one. The criticism is narrower but worth reading before you buy, because it is about how the seat behaves rather than whether it works.
One honest limit on what follows: the 3% one-star band (roughly 49 buyers) is not readable in our sample, so the complaints below are what buyers documented, not a complete census of every objection.
What parents loved
The most repeated praise. At about 4.2 kg parents reported it is "super lightweight and easy to move in and out of the car," which is why it keeps getting bought as the grandparent or second-car seat.
— Verified buyerReviewers described installation as "super easy" — there is no harness to route or re-thread, so switching it between vehicles is a genuinely quick job rather than a weekend project.
— Verified buyerParents reported children find it comfortable and like the hideaway cup holders, with one grandparent noting their grandson "loves pulling out the cup holders." Height-adjustable armrests and a multi-layer headrest do the rest.
— Verified buyerWhat frustrated some parents
The most important complaint, and it is structural: this booster installs with the vehicle belt only, with no lower anchors. One parent spelled out the consequence — you "have to remember to buckle the booster seat when there isn't a child sitting there (for projectile risk) — which might be annoying to have to remember daily." That is a habit you must build, not a defect you can fix.
— Critical reviewerBuyers coming from a harnessed convertible noticed the difference immediately, with one saying it "definitely feels flimsy compared to our Britax Harness" seat. The light weight that makes it portable is the same light weight that makes it feel less substantial.
— Critical reviewerNot universal, but documented: one grandparent reported that when their grandson first sat in it "he didn't find it comfortable — but has since gotten use to it." Expect a short adjustment period rather than instant approval.
— Critical reviewerBest for / skip if
Best for
- A second car, carpool or grandparent vehicle
- Kids who have truly outgrown a 5-point harness
- Parents who need to move a seat between cars often
- Getting the highback and backless stages in one buy
Skip if
- Your child still fits their harnessed seat
- You want a seat that stays anchored when empty
- You want the heft of a harnessed convertible
- You need lower-anchor (UAS) installation
Our verdict
At 8.3 / 10, the TurboBooster earns its popularity. It is inexpensive, it is light, it converts through two stages, and 92% of 1,648 buyers rated it 4 or 5 stars. For the job it is designed to do — positioning a vehicle belt correctly on a 4-to-10-year-old — parents reported it does that job well and without fuss.
The deductions are honest ones. It is loose in the car whenever a child is not in it, and that is a daily habit you have to adopt rather than a flaw you can engineer around. It also feels lighter-built than the harnessed seat most families arrive from, which is a real perception even where it is not a safety finding. Neither is a reason to avoid it; both are reasons to know what you are buying.
This is a summary of buyer consensus, not safety advice. Follow Graco’s height and weight limits, your vehicle manual, and Transport Canada guidance on when a child is ready to move from a harness to a booster.
