What Subarus can fit 3 car seats?
The Subaru model most reliably capable of three car seats across the back row is the Ascent, thanks to its roomier second row. In other Subarus, three-across configurations can be possible only in certain trims and with specific seat types, but it isn’t guaranteed and varies by year and model.
Three-across car seats depend on several factors: the width of the back seat, the types of car seats (infant, convertible, booster), and whether you install with LATCH or a seat belt. Always test-fit your own seats in the exact configuration you plan to use, and consult both the vehicle’s manual and the car seat manufacturer for confirmation.
Models most likely to fit three car seats across
Below is a look at Subaru models where three-across seating is more plausible, noting that success hinges on seat type and exact configuration.
- Subaru Ascent (3-row): The largest Subaru, commonly capable of three-across seating on the second row when using a bench; success depends on seat width and the specific car seats being used.
- Subaru Forester (2-row): The second row is wide enough in many trims to accommodate three smaller or narrow seats, such as two infant seats plus a booster, though bulky seats may limit options.
- Subaru Outback (2-row): With a fairly wide second row, three-across is possible in some configurations using slim infant/convertible seats and boosters.
- Subaru Legacy (2-row): The width of the rear bench in many model years can allow three seats with the right slim seats or boosters.
- Subaru Crosstrek (2-row): In tight situations, three-across can be challenging but may be feasible with very narrow seats; not guaranteed in every year/trim.
- Subaru Impreza (2-row): Similar to the Crosstrek, three-across is not guaranteed and depends on seat widths, but narrow infant seats can sometimes fit across the back.
Concluding note: Larger models like the Ascent offer the best odds for a true three-across setup in daily use. In smaller Subarus, three-across may be possible only with carefully chosen, slim car seats and specific configurations. Always verify with a hands-on fit.
Practical tips for maximizing three-car-seat chances
Before you start testing, read these guidelines to improve your chances of a successful three-across setup.
- Measure your car seat widths and compare them to the back seat width of the exact model year and trim you’re considering.
- Choose slim-profile car seats when planning a three-across arrangement (for example, narrower infant seats or compact convertible seats).
- Prefer belt installation for the middle position if LATCH is limited or not available in that seat, and follow the car seat manufacturer’s installation instructions closely.
- Boosters can be used in outer positions to free up the center for a narrower seat, depending on your vehicle’s belt geometry and tether options.
- In each configuration, ensure all seats are securely installed and that there is no interference with airbags, seat tracks, or seat adjustments.
Concluding: Always test-fit with your own seats and consult the car seat and vehicle manuals. If in doubt, a dealership demonstration or a certified Child Passenger Safety technician can help you confirm a safe three-across setup.
Summary
In summary, the Subaru Ascent offers the strongest odds for a true three-across setup in everyday use, especially on its broad second row. Other Subarus—Forester, Outback, Legacy, Crosstrek, and Impreza—may support three car seats across in certain configurations, but success depends on seat width, seat type, and exact year/trim. The safest approach is to test-fit with your specific seats and confirm with official manuals and manufacturers.
