Will the Britax Poplar fit in a 2015–2024 Chevrolet Colorado Crew Cab?

Yes — the Britax Poplar fits a 2015–2024 Chevrolet Colorado Crew Cab, with a caveat.
The Poplar is about 18.5" wide; the Colorado Crew Cab's usable rear bench is about 52". It fits one rear position comfortably. Three across is tight (55.5" needed vs 52"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.

Will the Britax Poplar fit in a 2015–2024 Chevrolet Colorado Crew Cab?

Yes — the Britax Poplar (18.5" wide) fits a single rear seating position in a 2015–2024 Chevrolet Colorado Crew Cab. 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 52" and three of these would need 55.5".

Can you fit three Poplars across a Colorado Crew Cab?

Probably not — three Poplars need about 55.5" but the Colorado Crew Cab's usable bench is only about 52". Consider a narrower seat — see our narrowest-seats guide.
