About SeatCheck

SeatCheck answers one stressful question fast: is this car seat still safe to use? We keep a hand-checked database of expiration policies for 14 major brands and their most popular models, each entry sourced from the manufacturer's own help pages and manuals.

The checker is free, runs entirely in your browser, and nothing you enter is uploaded anywhere.

How we source

Every brand page lists its sources. Where a manufacturer's policy varies by model or by year of manufacture, we say so rather than flattening it to one number. If you spot something out of date, the manufacturer's label on your own seat always wins.
