Pros
- One seat from the harness stage to a 120 lb booster

- Steel frame and two layers of side-impact protection
Cons
- Over 25 lb
- About 21 in wide, so nothing sizeable fits beside it
Our Verdict: Britax Grow With You ClickTight
The Britax Grow With You ClickTight scored 73 out of 100 across the three criteria we score every booster seat on, and took Best Harness-to-Booster Seat in our booster seat guide.
Britax makes it easy to get right. In harness mode the ClickTight panel swings up, you thread the belt, close it, and the seat locks in with no slack, and it carries a steel frame and two layers of side-impact protection.
Size is the trouble. It weighs over 25 lb and is about 21.5 in wide, so it takes up a whole seating position, which is why weight and size scored 5.5, the lowest in the guide.
Our Analysis, Comparisons and Test Results
Crash test
8 out of ten. The steel frame and two layers of energy management gave exceptional force dissipation in our crash testing.
Weight & size
5.5 out of ten. Heavy at over 25 lb and about 21.5 in wide, so it takes up a large share of any back seat.
Quality
8.5 out of ten. Industrial-grade steel frame construction with plush knit covers.
Should You Buy the Britax Grow With You ClickTight?
Buy it for a child who has just left the harness and a car where the seat will stay put.
If you only need a booster, the Alta V2 and the Solution G2 are far lighter and narrower.
Every booster seat here was scored on the same three criteria, so the question is not which one is good. It is which one suits what you will do with it most days.
