Smart Posture Trainer — Posture Sensor with Vibration Alert

You start the day sitting up straight, but after an hour of working from home you're slouching towards your screen again — without even noticing. That's exactly the 'without noticing' part this smart posture trainer tackles. You wear the small, discreet sensor on your back; the moment you start to slouch, you feel a gentle vibration as a friendly reminder. No restrictive strap, just a nudge that makes you aware of your posture. Ideal for working from home and long desk days. Please note: this is a comfort and training product, not a medical device.

Why you'll love this

• A nudge the moment you start to slouch — you catch yourself in the act
• A gentle vibration instead of restrictive straps
• Small and discreet: no one will know you're wearing it

Frequently asked questions

Is this right for me?
Do you want to sit up straighter, more consciously, while you work? This trainer gives you a nudge to help. If you have back complaints, consult a specialist. This is a comfort product, not a medical device.

How quickly will I receive it?
Usually 3–8 working days from our EU stock; if your item ships from a warehouse outside the EU, it typically takes 7–15 working days. You'll always receive a track & trace code.

What if it's not right for me after all?
You have a 14-day cooling-off period. Report your return by email; the direct cost of returning the item is for your own account — for a parcel this size, typically between €7 and €15. If the product arrives defective or the wrong item was delivered, we'll cover those costs. See our returns policy.

How long should I wear the sensor each day?
Start with one to two hours a day while working and build up gradually. The goal is to become more aware of your posture.

Safety and use

Use the sensor according to the included instructions and build up wearing time gradually. This is a comfort and training product, not a medical device: stop if you experience pain, tingling or skin irritation, and consult a doctor or physiotherapist for persistent back complaints. Keep the device and its small parts out of reach of children under 3 — choking hazard.
