With the Veer infant car seat adapters, attaching your infant car seat to the Cruiser XL frame is a breeze. These adapters are compatible with major brands of infant car seats including the Britax B-Safe 35, Britax B-Safe 35 Elite, Britax B-Safe Endeavours and Britax B-Safe Ultra. Once attached, you can place your car seat in any of four positions: facing you, facing the outside world, above the front seat or above the back seat of the Cruiser XL. Please note that the Cruiser XL can accommodate only one infant car seat. If you have twins aged 6 months or older, you should consider using the Toddler Comfort Seat.
