If it's depth you're worried about, the walls can be adjusted back. We had to move the walls several inches back for the UppaBaby risers to fit. I was minimally involved with Baby so not sure where else in strollers risers would be going and if we're supposed to have them, we didn't get them sent to us.
I ended up doing this - we’ll see if it comes back to bite me in the end once we get the signing.
