SE · Europe & UK · Lab test · weight 0.6 · 2015–2025

Swedish insurer's traffic-safety researchers assess rear-facing seats (9 months to 4-5 years) statically, without crash tests: 16 measured properties in three areas (rear-facing as long as possible, crash-protection features incl. Plus Test approval, minimising misuse). Grades are relative to the average of seats tested.

Scale: Betyg 1-4, higher is better. 2023-2025: 4 = >33% better than average, 3 = up to 33% better (Bra val level), 2 = up to 33% worse, 1 = >33% worse. 2015-2019 scale: 4 = very good/Bäst i test, 3 = Bra val, 2 = below average, 1 = undvik (avoid). Bra val label also requires no forward-facing approval under 105 cm and no serious safety flaws.
