towards prevention or correction of postural presentations. It has been specially designed for use
with the HOGGI Bingo-OT seat unit only, with full cooperation with HOGGI GmbH team.

to provide postural support and wheeled mobility to children with disabilities who are partially or
permanently non-ambulatory and limited to a sitting position.

unit and follow all instructions provided in the Bingo-OT/COBRA Base’s user manuals. It is the

used as recommend by the Hoggi Gmbh. This manual along with the Bingo-OT/COBRA Base's
user manuals must be passed on to the user of this product.

recline or remove the supports prior to raising the backrest angle to protect the child with
potential pinch points with the mechanisms, lateral trunk, pelvic supports and arm supports.
• Ensure the child’s fingers are clear of the base of the backrest or it’s tubes when reclining
because there is a potential crush point between this and the cushion.
• When using the hip belt or shoulder harness, ensure the position of the harness is anatomically
correct. Ensure the pad is not impeding on the throat.
