Stroller or Car-Seat Setup: Choose Between BOB Single, Duallie, and Graco Adapters

Match the adapter to your stroller configuration and infant car-seat brand: the key divide here is BOB single versus Duallie double use, plus Nuna/Cybex/Maxi-Cosi, Britax, or Graco/Baby Trend pairing.

Last updated Aug 9, 2026

Choosing a stroller or car-seat setup gets complicated when the adapter names sound nearly identical. The useful shortcut is to start with two non-negotiables: whether the stroller is a BOB single or a Duallie double, and which infant car-seat brand needs to connect. These four adapters separate into clear pairing paths rather than interchangeable alternatives.

Quick take

For a BOB single jogging stroller paired with Nuna, Cybex, or Maxi-Cosi, the two identically named BOB Single Car Seat Adapter listings are the direct match. They share model S12046000, but differ in condition and in how specifically the stroller and seat compatibility is described. The Bob Stroller Infant Car Seat Adapter for Duallie Double Strollers is the dedicated choice for a Duallie double stroller and Britax car seat. The Car Seat Adapter for BOB Gear Strollers Compatible with Graco Baby Trend addresses a different car-seat pairing, with Graco and Baby Trend named in its title.

Decision matrix

  • Single BOB stroller plus Nuna, Cybex, or Maxi-Cosi: Focus on either BOB Single Car Seat Adapter listing. Select based on the listed condition and whether the named stroller models and removable receivers in the used listing suit the setup.
  • Duallie double stroller plus Britax: The Bob Stroller Infant Car Seat Adapter for Duallie Double Strollers is the purpose-specific match, rather than either single-stroller adapter.
  • BOB Gear stroller plus Graco or Baby Trend: The grey-and-black Car Seat Adapter for BOB Gear Strollers Compatible with Graco Baby Trend is the listing aimed at that brand pairing.
  • Condition is your first filter: The Graco/Baby Trend adapter is marked New, the first BOB Single listing is marked New other, and the remaining single and Duallie adapters are marked Used.

Product notes

BOB Single Car Seat Adapter - Maxi Cosi, Nuna, Cybex Car Seats - New other

At USD 42.00, this BOB Gear adapter is positioned for a single jogging stroller paired with Nuna, Cybex, or Maxi-Cosi infant car seats. Its description identifies it as a genuine BOB Gear accessory and specifies metal and plastic construction. That makes it a sensible fit for someone who wants the stated brand pairing with a BOB single jogging stroller and prefers the listing's New other condition designation. The trade-off is its focused use case: it is described for select BOB single jogging strollers, so it does not address the Duallie double stroller and Britax combination represented elsewhere in this comparison.

BOB Single Car Seat Adapter - Maxi Cosi, Nuna, Cybex Car Seats - Used

The USD 34.95 used BOB Single adapter shares the same S12046000 model number and the same core Nuna, Cybex, and Maxi-Cosi purpose as the New other listing. It stands out through a more detailed compatibility description, naming Cybex Aton 2 and Cloud Q, several Maxi-Cosi models, Nuna Pipa and Pipa Lite, plus BOB Alterrain, Rambler, Revolution Flex, and Revolution Pro stroller lines. The description also includes an adapter frame and two removable receivers. Its concrete limitation is condition: it is listed as Used, which distinguishes it from the New other version of the same adapter.

Bob Stroller Infant Car Seat Adapter for Duallie Double Strollers

This USD 35.96 adapter is the clear specialist for an infant setup involving a Duallie Double stroller and a Britax car seat. Unlike the two BOB Single adapters, its title and description directly center a double-stroller application, while the listed black color and 31-inch length add useful identifying detail. Choose it when the stroller is specifically a Duallie double and Britax compatibility is the needed connection. The limitation is equally direct: this is not the listing for the Nuna, Cybex, or Maxi-Cosi pairings named on the BOB Single models. It is marked Used, with scuffs and scrapes described from normal use.

Car Seat Adapter for BOB Gear Strollers Compatible with Graco Baby Trend

At USD 75.94, the Car Seat Adapter for BOB Gear Strollers Compatible with Graco Baby Trend is the distinct choice for shoppers using either of those named car-seat brands. It is marked New and listed in grey and black, with aluminum noted in the material composition and a one-unit package quantity. Pick this adapter when Graco or Baby Trend compatibility is the deciding factor for a BOB Gear stroller setup. Its limitation is its narrower stated pairing focus: Graco and Baby Trend are the car-seat brands named here, while the other adapters are aimed at the separate Nuna/Cybex/Maxi-Cosi or Britax routes.

Final recommendation by use case

Choose the used BOB Single Car Seat Adapter when a named compatible BOB single stroller and its detailed Nuna, Cybex, or Maxi-Cosi compatibility list are the priority. Choose the New other BOB Single Car Seat Adapter for the same core single-stroller brand pairing in that listed condition. For a Duallie Double and Britax combination, go directly to the Bob Stroller Infant Car Seat Adapter for Duallie Double Strollers. If the car seat is Graco or Baby Trend, the Car Seat Adapter for BOB Gear Strollers Compatible with Graco Baby Trend is the targeted match.
