Will the Graco SlimFit fit in a 2014–2024 Mini Cooper Hardtop?

Yes — the Graco SlimFit fits a 2014–2024 Mini Cooper Hardtop, with a caveat.
The SlimFit is about 18.5" wide; the Cooper Hardtop's usable rear bench is about 44". It fits one rear position comfortably. Three across is tight (55.5" needed vs 44"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.

Always confirm the fit and install yourself before every trip. The SlimFit's width (Graco published spec (rotating cup holders stow to ~18.5 in)) and the Cooper Hardtop's rear-bench width (Very small car — narrow rear bench (~44"); typical for subcompact, approximate, verify install) are both approximate — confirm with a test-fit before buying.

Common questions

Will the Graco SlimFit fit in a 2014–2024 Mini Cooper Hardtop?

Yes — the Graco SlimFit (18.5" wide) fits a single rear seating position in a 2014–2024 Mini Cooper Hardtop. 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 44" and three of these would need 55.5".

Can you fit three SlimFits across a Cooper Hardtop?

Probably not — three SlimFits need about 55.5" but the Cooper Hardtop's usable bench is only about 44". Consider a narrower seat — see our narrowest-seats guide.
