## Indications for use
Chunc pediatric attendant controlled wheelchair is intended for clients with moderate to specialist needs and has been designed with the occupants and attendants need first and foremost. Chunc manual wheelchairs empower physically challenged persons by providing a means of mobility. This includes temporary and permanent conditions such as: Arthritis Tetraplegic Multiple Sclerosis Amputee Quadriplegic Polio Paraplegic Spina Bifida Cerebral Palsy Muscular Dystrophy and Any other immobilizing or debilitating condition The modular design of the wheelchair chassis, frame and seating allows for flexibility and ease of modification to suit postural, functional and social needs. This coupled with material choice and the frequent use of like parts across the wheelchair have enabled us to keep costs at a minimum. Attendant functions have been designed to be easily identifiable from engineered functions using unified adjustments with color coding which are also simple to use and maintain. By moving away from the cumbersome welded steel structures of conventional wheelchairs we have been able to utilize a selection of materials and manufacturing techniques to ensure the wheelchair is lightweight and therefore comfortable to use. Chunc is currently manufactured and marketed in the UK and has been approved by the National Health Service (NHS) and has the relevant CE marking. Chunc also provides the ability for Bus Transportation and motor vehicle transportation with the use of wheelchair tiedown and occupant restraints systems (WTORS) that meet the requirements of SAE 12249
