Will the Graco Milestone fit in a 2020–2024 Kia Soul?

Yes — the Graco Milestone fits a 2020–2024 Kia Soul, with a caveat.
The Milestone is about 19.5" wide; the Soul's usable rear bench is about 48". It fits one rear position comfortably. Three across is tight (58.5" needed vs 48"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.

Common questions

Will the Graco Milestone fit in a 2020–2024 Kia Soul?

Yes — the Graco Milestone (19.5" wide) fits a single rear seating position in a 2020–2024 Kia Soul. 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 48" and three of these would need 58.5".

Can you fit three Milestones across a Soul?

Probably not — three Milestones need about 58.5" but the Soul's usable bench is only about 48". Consider a narrower seat — see our narrowest-seats guide.
