Fixed hip supports narrow the seat around a child’s pelvis and give them a stable base to sit on. With the pelvis held, the trunk has something to work against and a child can hold their head and shoulders more easily through the day.
This version is supplied without covers. That suits a service replacing hardware where the covers are still in good order, and it suits a prescription where the covers are being ordered separately in a particular colour or replaced on a cycle of their own.
The fixed mounting sets the supports at a chosen width and holds them there, which is what you want for a child whose position is settled and who benefits from the same setup every time they are seated.
