In the Cargoo it is possible to add a single seat that comes including an adaptor. Choose this if you prefer only one seat in the Cargoo or e.g. if you need to carry three children (buy this combined with two rear end seats). If you already have the two rear end seats then add this seat in the middle towards the side. This enables you to carry an extra child. Buy one more and you have room for four.
For Kangaroo Luxe, Lite and Cargoo.
