How to Choose the Best Booster Seat
Decide between highback support and backless portability
The Graco Junior Maxi i-Size R129 is the only highback option listed, providing a 10-position height-adjustable headrest for children starting from 100cm (around 3.5 years). Backless models like the My Babiie MBCSB10 and Cozy N Safe Neo are restricted to taller children from 125cm (approx 6 years), but they are significantly more compact to carry and store.
Check whether you need i-Size height compliance or weight ratings
Models like the Kinderkraft I-Boost 2, My Babiie MBCSB10, and Cozy N Safe Neo meet the R129 i-Size standard, which uses child height (125-150cm) to judge fit. If you prefer traditional weight-based sizing, the MyChild Brundle covers Group 2/3 starting from 15kg, while the Cozy N Safe Tambu is rated specifically for Group 3 (22-36kg).
Compare seat padding and washable covers for comfort
The Cozy N Safe Tambu uses memory foam padding for longer journeys, whereas the Cozy N Safe Neo features a deep padded seat design and the MyChild Brundle includes padded armrests. If accidental spills are a concern, the Kinderkraft I-Boost 2 includes machine-washable covers for easy cleaning.
Weigh up seat weight against extra belt positioning aids
At only 700g, the MyChild Brundle is the lightest option for moving between cars, weighing less than the 1kg My Babiie MBCSB10 and the 1.2kg Kinderkraft I-Boost 2. However, the My Babiie MBCSB10 includes a dedicated shoulder belt positioning hook, and the Kinderkraft I-Boost 2 incorporates built-in belt guides to help seatbelts rest correctly.
