How Do Car Seats Fit in a 2025 Mini Countryman?
The verdict: The Mini Countryman is the brand’s largest vehicle and although it was updated for 2025 with more cabin space, its backseat is still tiny when it comes to accommodating some car seats. While we appreciated the Countryman’s easy-access Latch anchors, our rear-facing car seats needed more room. For this Car Seat Check, we tested the sport-oriented John Cooper Works edition.
Does it fit three car seats? No.
Take a look at how the Latch system and each car seat scored below in our Car Seat Check of the 2025 Mini Countryman.

Latch: Grade A
The two sets of lower anchors sit under flip-up plastic covers. The three top tether anchors sit three-quarters of the way down the seatback. All of the anchors are easy to find and use.
Infant Seat: Grade C
While it was easy to install this car seat thanks to accessible lower anchors, it impacted the front passenger’s legroom quite a bit. Our 5-foot-6-inch front passenger’s knees were uncomfortably close to the glove box.
Rear-Facing Convertible: Grade C
As with the infant seat, the convertible in rear form went in easily, but front passenger legroom was negatively impacted.
Forward-Facing Convertible: Grade A
After raising the head restraint to situate the convertible flush against the seatback, the convertible in forward mode fit well — we had no issues with the lower anchors or top tether anchor.
Booster: Grade A
We again raised the head restraint to make room for the booster’s high back. The SUV’s belt buckles are on stable stalks, so kids should be able to grasp and use them independently.
Grading Scale
A: Plenty of room for the car seat and the child; doesn’t impact driver or front-passenger legroom. Easy to find and connect to Latch and tether anchors. No fit issues involving head restraint or seat contouring. Easy access to the third row.
B: One room, fit or connection issue. Some problems accessing the third row when available.
C: Marginal room plus one fit or connection issue. Difficult to access the third row when available.
D: Insufficient room, plus multiple fit or connection issues.
F: Does not fit or is unsafe.
About Cars.com’s Car Seat Checks
Editors Jennifer Geiger and Jennifer Newman are certified child safety seat installation technicians.
For the Car Seat Check, we use a Chicco KeyFit 30 infant-safety seat, a Graco Contender 65 convertible seat and Graco TurboBooster seat. The front seats are adjusted for a 6-foot driver and a shorter passenger. The three child seats are installed in the second row. The booster seat sits behind the driver’s seat, and the infant and convertible seats are installed behind the front passenger seat.
We also install the forward-facing convertible in the second row’s middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit; a child sitting in the booster seat must be able to reach the seat belt buckle. If there’s a third row, we install the booster seat and a forward-facing convertible. Learn more about how we conduct our Car Seat Checks.
Parents should also remember that they can use the Latch system or a seat belt to install a car seat, and that Latch anchors have a weight limit of 65 pounds, including the weight of the child and the weight of the seat itself.
