Monterey 5 5isT FixSafe is 25% smaller than average booster seats. Each vehicle model is different and allows for various seating positions. Where it may fit 3 across in one vehicle, it cannot be guaranteed in all vehicle makes and models. Consumers should consult their vehicle owners manual for appropriate car seat placement locations within their vehicle for locations that may fit 3-across. The SPECS section of the Monterey 5isT FixSafe product page includes product dimensions that can be used to determine fitment with existing car seats in vehicle.
