This extension raises the back of the Cricket to support the upper trunk and shoulders, for a child who has outgrown the standard back height or who needs support carried further up than the seat unit gives on its own.
A taller back keeps the shoulders from falling behind the chest, which helps head position, breathing and line of sight. It is often the piece that makes a Cricket keep working for a growing child.
It is also the accessory that comes up when a chair is being set up for use with a head rest, since the head support needs something to mount to and work from.
