If you have a Stokke Steps Baby Set, you can adjust the seat and footrest to three different positions. To do this, first loosen the screws on the side of the seat using the included allen key. Then, slide the seat up or down to your desired position and retighten the screws. Next, use the allen key to loosen the screws on the underside of the footrest. Finally, adjust the footrest to your desired position and retighten those screws as well.
