Washing Instructions

Does this harness require a vehicle tether point?




No. This harness does not require any tethering; it is not a safety harness. It is simply attached to the vehicle seat with the securing straps.


If I can’t pass the strap between the seat and the backrest, what can I do?



This can be common. Most vehicles have a carpet flap at the rear which prevents the straps coming vertically around the seat. In virtually all cases the carpet can be cut with a pair of scissors or a knife to provide access through.



How do I Care for my Harness when it needs washing?


  • Harnesses must be cleaned by Hand washing only, in warm water up to 70 or 80 degrees.
  • Use a mild detergent/anti-bacterial liquid wash.
  • Mild disinfectant can be used.
  • Do not use Bleach or Tumble Dry your harness.

I just wanted to let you know that the car harness has been a great success with my client and  it has made an enormous difference to his quality of life and especially his ability to get out of the house and back to school this term.

The Houdini 22 is working really well for this active client. What the family really loves about it is, it only has 2 buckles when attaching him into the car. This child gets agitated if it takes too long to transfer him in or out of the car, and this harness is really quick to use. We put the torso section of the harness on him inside the house (where he can’t run away) and then hold on to the harness while walking him out to the car and just click it in. We love this as it is really easy to use. When he gets to school, he is always in a hurry – we just unclick it and he runs into the classroom and the teacher takes the harness off!
