Place the new seat on the seat bracket, lining up the screw holes in the seat with the appropriate holes on the bracket.

Note that the bracket has two sets of holes for mounting the seat, so choose the appropriate set for the height of the rider. A taller rider will use the further set while a shorter rider will use the set closer to the handlebars.

Insert the screws from the top of the seat, using your spanner to hold the nuts under the screws.
