The Houdini 13 Harness is a paediatric vehicle harness that features unique rear fastening for positioning children who have problems associated with attention or require postural support to travel safely in car. The Houdini 13 is designed so all of the buckles are behind the seat backrest and cannot be tampered with for extra safety. To fit the harness easy access is required all the way round the seat back and underneath the base of the seat cushion. Please note that this vehicle harness is not classed as safety harness but as a medical device for postural support. To comply with safety regulations, the vehicle safety belt must always be worn over the top of the harness.
