A small extra cushion for the Rabbit Up, used where a support needs padding out to sit correctly against a child. Bony prominences, an asymmetric trunk or a child at the lower end of a size band can all leave a gap that the standard padding does not fill.
Adding the cushion spreads the load across a wider area and keeps pressure off the spots that redden first. It also gives you a quiet way to fine tune a position without changing the whole support, which matters for a child who is sensitive about being adjusted. The cover wipes clean and the cushion comes off for laundering when it needs it.
