The Joolz Geo2 expandable set broadens both yours and your babies’ horizons without making your stroller any wider or any less maneuverable. The expansion set consists of a cot and a seat, which transform your Joolz Geo² into a duo stroller for your second child, or a twin stroller for twins. The stroller still folds down nice and compact with two seats, and there’s plenty of walking space for you. It has an ergonomic design that ensures comfortable transport from your baby’s birth, and for the years to come.
