3 across in a Ford F-150 SuperCrew

The widest bench in this list at about 56", and it is flat — the SuperCrew is quietly one of the best three-across vehicles you can buy. Make sure it is the SuperCrew and not the SuperCab; the rear seat is a different proposition entirely.

15 seats can go three across a 2015–2024 Ford F-150 SuperCrew.
The F-150 SuperCrew's usable rear bench is about 56". Three of the narrowest seats below clear it (3× width ≤ 55.5"). It's edge-to-edge — test-fit.
