Quick answer
Choose the Wiz Car Seat Adapter if you own a Mompush Wiz stroller and a Chicco KeyFit 30, Fit2, or similar model. Pick the Ultimate 2 Car Seat Adapter for a Mompush Ultimate 2 stroller with a Maxi-Cosi Mico or Nuna Pipa car seat. Always confirm your stroller model first—these adapters are not interchangeable.

Why stroller model matters first
Each Mompush car seat adapter is designed for a specific stroller frame. The Wiz Car Seat Adapter works only with the Mompush Wiz Stroller, while the Ultimate 2 Car Seat Adapter fits only the Mompush Ultimate 2 Stroller. If you already own an Ultimate 2 stroller, the adapter is included with your purchase—check your box before buying a separate one.
Mixing adapters across stroller models can lead to an unsafe fit. Always match the adapter to your stroller’s brand and series, not the car seat brand alone.
Car seat compatibility: Chicco vs. Maxi-Cosi / Nuna
The Wiz Car Seat Adapter supports Chicco infant car seats: KeyFit 30, KeyFit 30 Zip, KeyFit 30 Zip Air, Fit2, Fit2 Air, and Fit2 LE. If you use a Chicco seat, this is your only Mompush option.
The Ultimate 2 Car Seat Adapter is built for select Maxi-Cosi Mico AP, XP, Mico 30, Mico Max 30, and Nuna Pipa / Pipa Lite seats. It does not work with Chicco models. Choose this adapter if you have a Maxi-Cosi or Nuna car seat and an Ultimate 2 stroller.
Installation and weight limits
Both adapters use a simple click-and-secure mechanism. The Wiz adapter requires the car seat to be tightly secured to the stroller—double-check the connection before each use. The Ultimate 2 adapter follows a similar straightforward install. Neither adapter includes a weight limit in the catalog, so always follow your car seat manufacturer’s maximum weight and height guidelines.
Decision rules for choosing your adapter
- Match your stroller first: Identify whether you have a Mompush Wiz or Ultimate 2 stroller. The adapter must match the stroller model exactly—using the wrong one compromises safety. Check your stroller’s nameplate or purchase receipt before ordering.
- Confirm your car seat brand: Wiz adapter works with Chicco seats only. Ultimate 2 adapter works with Maxi-Cosi and Nuna seats only. No cross-compatibility between these groups. If you have a Chicco seat, choose the Wiz adapter. If you have a Maxi-Cosi or Nuna, choose the Ultimate 2 adapter.
- Avoid duplicate purchases: The Ultimate 2 Car Seat Adapter comes included with the Mompush Ultimate 2 stroller. If you already own that stroller, you already have the adapter. Only buy the Ultimate 2 adapter as a replacement or spare.
