Where a child needs trunk support in sitting but not full harnessing, the four point vest is usually the right first step. It holds the shoulders and upper trunk back into the backrest and leaves the arms free for play, school work and self feeding.
Four anchor points spread the correction across the chest, so the child is supported broadly across the chest. Carers can tension it quickly and release it just as fast, which is worth a lot at the end of a school day. Therapists get a stable trunk to work from, which is often what unlocks head control and hand function further up the chain.
Five sizes follow the chair sizes, so as the seat is adjusted or the child moves up a frame the vest can follow.
