Methodology & sources
We organize public facts to help you shortlist — and we're explicit about what only your manuals and a technician can decide.
What we publish
- Manufacturer-stated specs: stage/modes, the narrow-for-3-across flag (by published width), extended-rear-facing capability, FAA approval, and lightweight/travel suitability.
- We don't store exact weight limits as gospel — confirm them on the manufacturer's page (we link the method).
What we never do
- No claim that a seat fits a specific vehicle — that's a test-fit + manual question, and we say so on every page.
- No safety ratings of our own; we point to NHTSA and certified CPSTs.
- No fabricated specs; dated "last verified" on every page.
