Cybex Priam 4: Will the Cybex Priam 4 carrycot will fit on to the older Priam frames?

Hey, Angelina,

Officially, the carrycot is only Priam 4 and e-Priam 2 compatible, so I will unfortunately answer you no. In theory, the attachment system looks similar, but I think they updated some components, so you won't fit it right onto the older frames anymore.
