Can I use my Venicci car seat on another pushchair?

Hi, Beck,

It depends on the car seat you have, as there are multiple models. If the adapters for it - even now, for the Venicci frame - have this U-shaped attachment system, you can pair the car seat up with ANY stroller frame that has Maxi-Cosi/Cybex adapters available. Like this (the upper part have to have that U, the lower part can differ):

If the upper part of your adapters for your car seat is different, you won't be able to pair it up with other stroller chassis than a Venicci which offers those compatible adaptors.
