Choosing a stroller or car-seat setup starts with one question: are you adding an infant seat to a stroller you already own, seeking a compact frame to use with an infant seat, or starting with a coordinated stroller-and-car-seat combination? The four options here serve distinctly different roles. Two are BOB Gear Duallie adapters made for particular infant-car-seat families, while Graco offers both a lightweight stroller frame and a complete travel system.
Quick take
- For an existing BOB Duallie and a Britax or BOB infant seat: Choose the Bob Gear Infant Car Seat Adapter for Bob Duallie Jogging Strollers S02984600. It is the Britax/BOB-specific route and adds a snack tray for the second child.
- For an existing BOB Duallie and a Chicco infant seat: The BOB Gear Duallie Jogging Stroller Infant Car Seats Adapter for Chicco Branded is the focused match. Its compatibility list includes Chicco KeyFit and Fit2 models.
- For the smallest stroller-frame approach: Pick the Graco GoMax Frame Stroller Compact Lightweight Universal Car Seat Carrier Black. Its 8.7 lb stroller-frame weight and diaper-bag-sized fold language suit a compact setup.
- For a full stroller-plus-infant-car-seat combination: Select the Graco Merge 360 Travel System Stroller SnugRide Lite DLX Infant Carrier Combo. It includes the SnugRide Lite DLX Infant Car Seat and a stroller with four wheels that rotate 360° at the push of a button.
The listed range runs from $119.18 to $275.99, with the lowest price 57% below the highest. That gap largely reflects the difference between an adapter or frame and a combination that includes both stroller and infant car seat.

Decision matrix
Choose by the gear already in your household. The two BOB Gear choices are not interchangeable general stroller purchases: each is an adapter for BOB Duallie jogging strollers from specified 2016-and-later lines. The S02984600 version connects compatible Britax and BOB seats, while S02984700 is built around listed Chicco models. Start with the infant car seat you intend to use, then choose the matching adapter.
Choose by how much is included. The GoMax is a stroller frame; an infant car seat is separate. Its role is to create a Graco-car-seat travel arrangement without bringing along a conventional full stroller. The Merge 360 is the all-in-one direction because the title and description include both stroller and infant carrier.
Choose by maneuvering and storage priorities. GoMax emphasizes a very compact fold, height-adjustable handlebar, front-wheel suspension, and easy-access basket. Merge 360 emphasizes four-wheel 360° rotation, a one-hand reclining seat, canopy, child tray, parent cup holder, and storage. Those differences make GoMax the more streamlined frame option and Merge 360 the fuller everyday-stroller format.
Keep the BOB adapter use case specific. Both BOB Gear descriptions state that jogging or running with the adapter and infant car seat in use is not recommended. They are intended to convert a compatible Duallie into a travel-system arrangement rather than to preserve the jogging use case during infant-seat use.
Concise product notes
Bob Gear Infant Car Seat Adapter for Bob Duallie Jogging Strollers S02984600
This adapter makes sense when a compatible BOB Duallie stroller and a Britax or BOB infant car seat are already part of the plan. The named compatible seats include B-Safe Gen2 variants, B-Safe 35 models, B-Safe Ultra, and Endeavours, and the adapter permits one infant seat while providing a snack tray for the second child. No tools are required for installation, and it folds with the stroller. At USD 144.53, it is less than the Chicco-focused BOB adapter. Its limitation is narrow fit: it is for the stated Britax and BOB seat families and specified Duallie stroller lines, not a standalone stroller or included car seat.
BOB Gear Duallie Jogging Stroller Infant Car Seats Adapter for Chicco Branded
For a Chicco-centered setup, this BOB Gear adapter is the direct choice. It lists compatibility with Chicco KeyFit, KeyFit 30, KeyFit 30 Zip, KeyFit Zip Air, KeyFit Magic, and Fit2 infant car seats, and it also includes a snack tray for the second child. The no-tool installation and fold-with-stroller design help keep the converted Duallie arrangement straightforward. At USD 171.57, it is the higher-priced of the two adapters. The tradeoff is equally specific compatibility: the adapter is for listed Chicco seats and designated 2016-and-later BOB Duallie stroller families, so it does not replace either a stroller or infant car seat.
Graco GoMax Frame Stroller Compact Lightweight Universal Car Seat Carrier Black
The Graco GoMax frame is the concise answer for families who want their Graco infant seat to supply the seating portion of the setup. It accepts the GoMax Insta-Install Infant Car Seat or Graco SnugRide infant car seats, has a listed stroller-frame weight of 8.7 lb, and folds to a compact size described as practically as small as a diaper bag. A height-adjustable handlebar, front-wheel suspension, and large storage basket broaden its day-to-day utility. At USD 119.18, it is the lowest-priced option here. The key limitation is scope: an infant car seat is sold separately, so GoMax is not the complete stroller-and-car-seat combination offered by Merge 360.
Graco Merge 360 Travel System Stroller SnugRide Lite DLX Infant Carrier Combo
Choose the Graco Merge 360 when the goal is to begin with both major pieces together. The combination includes the SnugRide Lite DLX Infant Car Seat, described for rear-facing infants from 4-30 lb and up to 32 inches, alongside a stroller with 360° wheel rotation, a convertible 3- or 5-point no-rethread harness, one-hand recline, canopy, and removable child tray. A leatherette handle, parent cup holder, and ample storage add convenience-oriented details. Its USD 275.99 price is the highest in this comparison. That reflects the broader included setup, but it may be more equipment than needed for someone who already owns a compatible car seat or BOB Duallie stroller.
Final recommendation
Match the choice to the gear you already have rather than comparing all four as like-for-like strollers. A compatible Britax or BOB seat points to the S02984600 adapter; a compatible Chicco seat points to S02984700. If a Graco infant seat is already chosen and minimal folded size is the priority, GoMax is the streamlined frame option. For a stroller or car-seat setup that begins with an included SnugRide Lite DLX carrier and adds the Merge 360's rotating-wheel stroller, the complete travel system is the clearest fit.
