Which Maxi-Cosi UPPAbaby Adapter Do You Need? (By Stroller Model)
Short answer: a Maxi-Cosi infant seat always needs an adapter on an UPPAbaby stroller — Maxi-Cosi isn’t UPPAbaby’s own brand, so it never clicks straight onto the frame. UPPAbaby makes a different adapter for each stroller line, and the right one is chosen by your stroller, not your seat: 0919-UMA-WW for the Vista and Cruz, 0918-MXA-WW for the Minu, and 0901-RMX-WW for the Ridge. Below is every UPPAbaby stroller with its exact Maxi-Cosi adapter part, the four Maxi-Cosi seats UPPAbaby actually lists, and the one Maxi-Cosi seat that officially doesn’t fit.
Every pairing gets one of three verdicts: Fits the seat clicks directly onto the frame, no adapter · Adapter compatible with a named adapter part · No fit not supported by the manufacturer.
The verdict: Maxi-Cosi on UPPAbaby is always an “Adapter” pairing
UPPAbaby designs its strollers to take its own Mesa infant seat with a direct click-in and no adapter. A Maxi-Cosi seat is a different brand with a different mounting bar, so it can never click straight onto an UPPAbaby frame — it needs a bridging adapter that matches your specific stroller on one end and the Maxi-Cosi (Mico-family) mounting style on the other. The good news: UPPAbaby publishes an official adapter for each of its current full-size and compact strollers, so this is a solved problem as long as you buy the part number that matches your stroller.
The same adapter also carries the matching Nuna, Cybex and Clek seats — UPPAbaby groups those brands together because they share a similar belly-bar release. That’s why the box is usually labeled “Maxi-Cosi / Nuna / Cybex.” If you want the wider picture of how these grouped adapters work, see our car seat adapter guide and the explainer on whether a universal car seat adapter exists.
Which Maxi-Cosi UPPAbaby adapter you need, by stroller

|---|---|---|
| Vista (2015–2019), Vista V2, Vista V3 | 0919-UMA-WW (single / upper position) | Adapter |
| Cruz (2015–2019), Cruz V2, Cruz V3 | 0919-UMA-WW | Adapter |
| Vista — second seat (double, lower position) | 0918-LMA-WW (lower adapter) | Adapter |
| Minu, Minu V2 | 0918-MXA-WW | Adapter |
| Ridge, Ridge V2 | 0901-RMX-WW | Adapter |

Vista & Cruz — the standard case
For a single Maxi-Cosi seat on a Vista or Cruz, the part is 0919-UMA-WW. UPPAbaby lists it as compatible with the Vista (2015–2019), Vista V2 and Vista V3, and the Cruz (2015–2019), Cruz V2 and Cruz V3 — it is not compatible with pre-2015 Vista frames. It’s a no-tools, color-coded click that sits your seat in the upper (primary) position, and the stroller still folds with the adapters attached.
If you’re running a Vista as a double and want the Maxi-Cosi seat in the lower spot, that’s a separate part — the lower car seat adapter 0918-LMA-WW. Most single-seat parents never need it; it only matters for a two-seat travel-system setup. This is the detail retailer listings tend to blur, and buying the wrong one of the two is the most common Vista adapter mistake.
Minu & Ridge — different strollers, different parts
The compact Minu and Minu V2 use adapter 0918-MXA-WW. The all-terrain Ridge and Ridge V2 use 0901-RMX-WW. These are not interchangeable with the Vista/Cruz part or with each other — each is shaped for that stroller’s own frame receivers, even though all of them accept the same list of Maxi-Cosi seats. Match the adapter to the stroller name on your frame, not to a photo that “looks the same.”
One scope note: UPPAbaby publishes Maxi-Cosi adapters for the Vista, Cruz, Minu and Ridge. Its umbrella-fold lightweight strollers (the discontinued G-Luxe / G-Lite and the G-Link) aren’t in the adapter lineup — those frames weren’t built to carry an infant car seat, so there’s no official Maxi-Cosi part for them.
Which Maxi-Cosi seats are actually on the list
Every one of these adapters names the same four Maxi-Cosi infant seats — all from the Mico family:
- Maxi-Cosi Mico NXT
- Maxi-Cosi Mico Max 30
- Maxi-Cosi Mico Max Plus
- Maxi-Cosi Mico AP
Two honest caveats sit on top of that list. First, the Maxi-Cosi Prezi is explicitly called out as not compatible — a genuine No fit, not an oversight. Second, if your Maxi-Cosi seat isn’t one of the four Mico models above — for example a newer or non-US model, or a non-Mico Maxi-Cosi seat — treat it as not officially supported until you confirm it on UPPAbaby’s current chart. It may physically resemble a listed seat, but a pairing no manufacturer has published isn’t a verified pairing, and on an infant seat that’s a safety line we don’t cross by guessing.
How to buy the right one in 30 seconds
- Read your stroller name and version off the frame (Vista V2, Cruz V3, Minu, Ridge…). The adapter is chosen by this, first.
- Confirm your Maxi-Cosi seat is a Mico (NXT, Max 30, Max Plus, or AP). If it’s a Prezi, stop — there’s no fit. If it’s anything else, check the chart before buying.
- Buy by part number —
0919-UMA-WW(Vista/Cruz),0918-MXA-WW(Minu), or0901-RMX-WW(Ridge). Only add the lower adapter0918-LMA-WWif you’re building a Vista double. - Test the click. The seat should lock with a firm, definite click and no lift or rock. If it takes force or can be lifted off, it’s the wrong part — re-check.
An infant seat on a stroller is only as safe as its attachment, so the part number really is the fit here — two adapters with near-identical names can serve different stroller frames. When in doubt, confirm against UPPAbaby’s own compatibility page before you buy, because adapters and model-years change.

Confirm before you buy. Compatibility and adapter part numbers change with model-years, and a wrong adapter is a safety issue. We cite each manufacturer’s own chart and show when we last verified it — but always confirm the exact pairing on the manufacturer’s current compatibility page or with their support before purchasing.
