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 and is classified as a challenging behaviour car seat.
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 info@incarsafetycentre.co.uk 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.
Magnetic Harness — Sizing Guide for Parents
The Magnet Vest is a magnetic safety harness designed to keep a child secure and comfortable in a wheelchair or seating system. Here's what parents need to know when choosing the right size.
Which size does my child need?
| Size | Best suited for |
|---|---|
| Small | Ages 4–12 years approx. (must be used together with a booster seat) |
| Medium (Standard) | Age 8 years approx. through to adulthood |
| Large | Adults from around 5ft 9" tall and taller |
Understanding the measurements
The vest is measured at four key points:
- A – Bib height: how far the front panel extends down the chest
- B – Width at shoulders: the distance across the top of the vest
- C – Width at neck: the gap at the neckline
- D – Bib width: the width of the vest at its widest point across the front
Sizing chart (in mm)
| Measurement | Small | Medium | Large |
|---|---|---|---|
| A – Bib height | 220mm | 260mm | 380mm |
| B – Width at shoulders | 210mm | 250mm | 340mm |
| C – Width at neck | 100mm | 120mm | 180mm |
| D – Bib width | 230mm | 290mm | 370mm |
Helpful notes from the manufacturer
- Bib height (A) is the most important measurement — it should be judged in relation to your child's sternum line (roughly where the breastbone ends). The harness neckline shouldn't sit too close to the throat, so use the sternum line as an upper guide.
- Neck width (C) has some flexibility, since the webbing straps adjust in use — but care should be taken to prevent chafing.
- Bib width (D) isn't a strict limiting factor, as the webbing continues around your child's waist for a secure fit.
In short
If you're unsure which size is right, the sternum line measurement (A) is the one to focus on first — it ensures the harness sits safely and comfortably without being too close to your child's neck.

MUST BE USED IN CONJUNCTION WITH THE 3-POINT SEATBELT This product should be used on a risk assessment basis only. This can be carried out by the parent/guardian.

Fantastic product. It is perfect for my child. Having peace of mind they and I am safe is transformative. The staff are super supportive and helpful.
Fantastic seat and harness, this has stopped our child escaping fron his seat.
Great car seat, the harness takes a little getting used to but once mastered it takes seconds to do up and undo.
Makes you feel relaxed to know that your child is in completely secure and safe.
Lovely helpful staff that talked us through it once fitted.
Axkid booster seat itself is sturdy and easy adjustable ,height and width adjusts with one click. The magnetic harness however is not fitted to the seat and is extraordinary to fit and adjust. I'm still not using it as can't get proper fit. Nowhere to fix the shoulder straps to stop them rising up and minimal instructions, also magnets really s.all and fiddly.
