📋 目次
1What age, height, and weight range is a Group 3 booster seat suitable for?
Group 3 booster seats are for children aged 6–12 years, typically 120–150 cm tall and 15–36 kg. They’re designed for kids who’ve outgrown forward-facing car seats but still need head and seat support for proper 3-point belt positioning.
2Should I choose a high-back or backless booster seat?
High-back boosters offer better head and neck support, especially in vehicles with low seat backs, and often include built-in harnesses. Backless boosters are more portable and suitable for older kids with good posture and mature seat belt fit in most cars.
3What safety features should I prioritize in a Group 3 booster?
Look for ISOFIX or belt installation for stability, a 3-point harness or belt-positioning system, and side-impact protection. Seats with adjustable headrests and anti-rebound bars enhance safety in a crash by reducing forward and lateral movement.
4How do I know if the booster seat fits my child properly?
The seat belt should lie flat across the shoulder and lap, not dig into the neck or stomach. The child’s back should be fully supported, and their knees should comfortably bend at the seat edge. If they slouch or climb out, the seat may be too small or not right for their maturity level.
5Are LATCH (ISOFIX) attachments worth the extra cost?
Yes — ISOFIX reduces installation errors and provides a more secure fit than seat belts. While not required for Group 3 boosters, it’s a valuable feature for easier setup and added peace of mind, especially for parents who frequently switch vehicles or install the seat themselves.
