These wedges narrow the Cricket seat, bringing the sides in so a smaller child sits centred and supported, not floating in a seat that is too wide for them.
Getting the width right is what keeps the pelvis square. Too much room and the child settles against one side, the trunk follows and the whole posture goes with it. Narrowing the seat now also means the same chair still fits in two years, once the wedges come out.
They fit against the seat side parts, so those need to be on the chair for the wedges to work.
