The Magnetic Harness offers additional restraint to support passengers who may otherwise open regular harness buckles. This harness is secured to the vehicle seat and is fastened at the front of the occupant. The design of this harness is effective for passengers who would otherwise remove themselves from standard products. The front panels are shaped for support and comfort. You push the ‘magnetic buttons’ shut to secure the harness and simply use the magnetised keys to release them again. This harness can be used in a car or a bus. Suitable for children up to mid-teenage. It can be opened in an emergency by simply pressing the buckle at the rear of the seat.

It fits perfectly with this car seat which is why we have paired it, to get the best use possible.

The car seat will be sent in the colour we have available unless otherwise stated by the customer. Please contact us at to specify a colour, or if you have any further questions.

Price includes the cost of our Seat Belt Cutter & Window Hammer that comes with a window sticker that explains where the seat belt cutter is kept, in case of emergencies.
