Infant Car Seats Compatible with BOB Revolution Flex Duallie

Running with a double jogging stroller and a newborn takes planning, and the BOB Revolution Flex Duallie is only as ready for a newborn as the infant car seat you pair with it. This collection brings together the infant car seats and adapters that mount directly to the Flex Duallie's frame, letting you roll from the car to the trail without waking a sleeping baby. One important detail to keep in mind: the Flex Duallie accepts only one infant car seat at a time, making it the right setup for a baby-plus-toddler combination rather than infant twins.

Choosing the Right Infant Car Seat for the BOB Revolution Flex Duallie

• Adapter fit by model year: Each car seat brand requires its own dedicated adapter, and that adapter must be rated for the double BOB frame specifically. Confirming the correct adapter before you order saves a return trip.
• Weight range and shell height: Most infant car seats in this collection cover roughly 4 to 35 pounds. If your baby is tracking long on height, look for seats with extended headrest room and higher shell-height limits rather than relying on weight limits alone.
• Base installation method: Most seats here install using a stay-in-car base with LATCH or seatbelt routing. Some bases add a load leg or anti-rebound bar for additional stability in the vehicle.
• Canopy depth: A jogging stroller exposes your baby to more direct sun and wind than a typical side-by-side double stroller. Prioritize infant seats with deep, multi-panel canopies and UPF-rated fabric.
• Carrier weight: On long park runs or trail walks, you will lift the carrier in and out repeatedly. Seats in the 8-to-10-pound range reduce fatigue noticeably over the course of a morning.
• No-jog rule: An infant car seat attached to the BOB is approved for strolling only. You must not jog with an infant car seat in place; the running brake and forward-fixed front wheel are for use without the infant seat.

Brands That Pair with the Flex Duallie

The adapters sold through our BOB Baby Gear collection cover the major U.S. infant car seat brands, so you are not locked into a single manufacturer. Chicco KeyFit and KeyFit 35 owners will find a dedicated Chicco adapter that slots into the BOB's attachment points and holds the seat at a safe, ergonomic angle. Britax and BOB-branded B-Safe seats use their own adapter, covering the B-Safe, B-Safe 35, B-Safe Ultra, Endeavours, and Chaperone. Graco SnugRide Click Connect and Classic Connect owners have a Graco-specific adapter as well. Each adapter is sold separately from the infant car seat, and all are available in the BOB Baby Gear collection alongside BOB-specific accessories. If you are comparing infant car seat options more broadly, our best-selling car seats and full car seats collection show the complete range we carry, including options compatible with other stroller systems.

If you are unsure which adapter matches your exact Flex Duallie model year, our gear team can help you confirm the right fit before you order. Parents already using a Chicco KeyFit seat, for example, will find the crossover particularly straightforward: the same seat that clicks into the base in your car connects directly to the BOB frame via adapter, giving you a true travel system from birth through the infant stage without buying a second car seat.
