Vibrating posture trainer
A small unit worn between the shoulder blades that vibrates discreetly as soon as the back rounds. Where a strap constrains you all the time, this one does nothing as long as the position holds — and you are the one who straightens up.
Shipped from Europe within 24 to 48 hours
Shipped from our European warehouse, prepared within 24 to 48 hours. Nothing ships from Asia, no customs fees on delivery. Shipping €7.99 in France, free from €65; from €5.90 elsewhere in the European Union — the exact amount is shown before you pay.
14 days to change your mind
From the day you receive it. You write to us, we arrange the return, we refund you — without you having to justify anything. That is the right of withdrawal: it exists so you can change your mind, no reason needed.
2-year warranty — if the product is faulty
It covers defects: a product that stops working, breaks on its own or does not do what its page says. Free repair or replacement, plus 6 extra months of warranty after a repair. It does not cover changing your mind — that is what the 14 days above are for — nor normal wear or accidental damage.
Electrical device: CE marking and recycling
Intended for the European market, with a European plug and CE marking. At end of life, do not throw it away with household waste: bring it to a recycling centre or a WEEE collection point (a shop, a drop-off bin). The crossed-out bin symbol on the product is the reminder.

At the end of a day sitting down, the shoulders have rolled forward....

An office chair never fills the hollow of the lower back. The gel...
You do not see yourself slumping. The posture trainer is worn between the shoulder blades: you record your position while sitting up straight, and it vibrates as soon as you move away from it. It holds nothing — it signals. The difference matters: you are the one who straightens up, and the movement ends up coming on its own.
What the signal changes
- The slumping you do not feel, the kind that comes in the second hour at the screen.
- The permanent constraint of a strap you end up taking off after three days.
- The reminder that never comes: nobody in the office is going to tell you to sit up straight.
- The cable: it recharges over USB-C and is used cable-free.

Signalling, or holding
It is a position reminder, not a treatment. If your pain persists, talk to a healthcare professional.

- The manufacturer does not publish a battery life: we cannot quote you one.
- Comes in grey and black. A comfort item, it is not a medical device.

Your questions
The ones we actually get asked. Click to expand.
How does it know I am not sitting well?
You record the starting position while sitting up straight, and the device vibrates when you move away from it. It is a tilt sensor, not a diagnosis.
Can the vibration be heard?
No, it is felt. It is made to call you to order, not to be heard by the next office along.
What is the battery life?
The manufacturer states a full charge in an hour and a half but does not publish a battery life. We would rather not put forward a figure we cannot check.
What is the difference with a strap corrector?
The strap holds you. This one does not hold you: it signals to you. You are the one who straightens up, and that is what makes the difference over time.
