These wedges sit behind the Cricket back upholstery and let you give the back some contour. Used low, they fill in behind the lumbar spine and help hold the pelvis upright. Used higher, they bring support forward where a child has a curve or drops back on one side.
For a clinician this is a quick way to build a bit of contour into a light folding chair, and it can be adjusted at review without changing the seat unit.
They are a sensible first step for a child who slides into a posterior pelvic tilt in the chair, before anything more involved is considered.
