*High Back Booster not included*
The Magnetic Harness offers additional restraint to support passengers who may otherwise open regular harness buckles. This harness is secured to the high back booster 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.
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.

My son previously had a Crelling harness but had worked out how to unclip the straps and I was at a lose to what to use next.
So far the magnetic harness is working so well and I have high hopes it’ll work moving forward. It’s a little tricky installing due to adjusting in the back but once sized up correctly it’s so easy to use.
Staff at the Essex branch of in car safety were great and explained everything and answered all my questions. Would 100% recommend
Thank you so much to the lovely ladies at towcester theu were so amazing with my son and helped me understand how to use the product.
amazing just amazing my 6yr old grandson hates it as he cannot escape now
