Will the Cosco Scenera Next fit in a 2018–2023 Kia Rio?

Yes — the Cosco Scenera Next fits a 2018–2023 Kia Rio, with a caveat.
The Scenera Next is about 17" wide; the Rio's usable rear bench is about 47". It fits one rear position comfortably. Three across is tight (51" needed vs 47"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.

Yes — the Cosco Scenera Next (17" wide) fits a single rear seating position in a 2018–2023 Kia Rio. 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 47" and three of these would need 51".

Can you fit three Scenera Nexts across a Rio?

Probably not — three Scenera Nexts need about 51" but the Rio's usable bench is only about 47". Consider a narrower seat — see our narrowest-seats guide.
