  "title": "Double stroller adapters for two car seats",
  "question": "Which double stroller adapters allow two car seats to be used at once?",
  "answer": "Bugaboo Donkey Twin adapters for Maxi-Cosi car seats (855180MC02): The video shows the twin adapter assembled by twisting its two halves together into one bar, then clicking the bar across the Donkey frame until both sides lock. The adapter connects a Maxi-Cosi or Nuna Pipa car seat to a Bugaboo Donkey using a click-and-go system. With two Maxi-Cosi seats mounted, users report the Donkey becomes very wide and can fail to pass some shop alarm gates, a supermarket checkout except the extra-wide one, and some hospital department doors.\nPEG Ypsi Double Adapter: The set includes the upper and lower adapters needed to create space between the main stroller seat and lower Companion Seat. The maker's USA/Canada manual says the Ypsi/Z4 double adapters can be used only on the Ypsi/Z4 chassis model numbers IP24* and IPMS32*, while the maker's Europe manual also lists IP38*; the two manuals disagree on the compatible chassis model numbers.\nUPPAbaby 2024 UPPAbaby Vista Lower Adapters - Bassinet / Mesa Series Infant Car Seats: The 2024 Lower Adapters let a UPPAbaby Bassinet or Mesa car seat attach to a Vista stroller as a secondary seat. The store page lists compatibility with RumbleSeat V2+, UPPAbaby Bassinet, Mesa V2 and Mesa Max infant car seats. The lower position is not for the regular Vista V2 stroller seat; the seat made for the lower position has a lower weight limit to prevent the stroller flipping forward.\nVeer Car Seat Adapter for &Roll / &Jog - Graco: Up to 2 adapters can be used on &Roll with the Second Seat Adapter Kit; only 1 infant car seat can be used on &Jog. Attaches to &Roll or &Jog frame to use an infant car seat. Adapter weighs 0.75 lbs.",
