Will the Chicco Fit4 fit in a 2017–2021 Subaru Impreza?

Yes — the Chicco Fit4 fits a 2017–2021 Subaru Impreza, with a caveat.
The Fit4 is about 19" wide; the Impreza's usable rear bench is about 49". It fits one rear position comfortably. Three across is tight (57" needed vs 49"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.

Common questions

Will the Chicco Fit4 fit in a 2017–2021 Subaru Impreza?

Yes — the Chicco Fit4 (19" wide) fits a single rear seating position in a 2017–2021 Subaru Impreza. Because this vehicle has limited rear legroom, a rear-facing install may require sliding the front seat forward. Three across is tight — its rear bench is about 49" and three of these would need 57".

Can you fit three Fit4s across a Impreza?

Probably not — three Fit4s need about 57" but the Impreza's usable bench is only about 49". Consider a narrower seat — see our narrowest-seats guide.
