There are 2 simple ways to fold the Stella pushchair:
With the seat unit on the frame
The seat needs to be in forward-facing postion with the backrest put forward. For more compact folding, fully lower the handlebar. The pushchair can stand upright when folded and locks automatically.
Without the seat on the frame
The pushchair will fold flat without the seat unit. To fold, push the central button below the seat frame and rotate the front wheels inside the frame. Front wheels should be in swivel mode.
