Posa Smart Posture Trainer
A discreet clip for your upper back that gives a gentle buzz the moment you slouch — quietly turning good posture into a habit. Not a stiff brace.

Nobody decides to slouch
It happens quietly. You sit up straight, get absorbed in something, and twenty minutes later you are folded over the desk again. It was never about willpower — it is that nothing tells you the moment it happens.
A brace holds you up. It never teaches you to.
Straps do their job while you are wearing them. The real question is what your back does in the hour after one comes off.
It does the work for you
Webbing and tension pull your shoulders back. Nothing is being asked of you while it is on.
So it ends up in a drawer
Rigid straps dig in under the arms. Most people give one a few days, then quietly stop.
And nothing has changed
Take it off and you sit exactly as you did before, because the habit itself was never touched.
Posa works the other way round. It never holds you in place — it notices the moment you drop and leaves the correcting to you, because that is the part that stays with you once the device is off.
How it works
Clip it on
Sits discreetly on your upper back — under any shirt.
It buzzes when you slouch
A gentle vibration — your private reminder to lift up.
You straighten & build the habit
Day by day, sitting tall starts to feel automatic.
What you are actually clipping on
Four things it does, and nothing it does not.
A buzz, not an alarm
Silent to everyone but you. It vibrates the moment your upper back rounds forward, and stops when you lift.
Nobody sees it
It sits flat between the shoulder blades, under the shirt you are already wearing. No straps across the chest.
About a week per charge
Typical daily wear runs roughly a week. Tops up over USB-C, so a Sunday evening covers the work week.
Clips on in a second
One clip, no buckles to adjust and nothing to tighten. On before you have finished your coffee.
Your 14-day transformation
A simple, guided path from slouching to effortless. Tap each phase, or swipe.
How Posa compares
The brace is the thing most people try first, so it goes first. Tap to switch.
A brace does hold you upright, and that is exactly the trade-off: the muscles that should hold you get to switch off. Posa prompts, you straighten.

Free digital bonus, included with every kit

Customer Reviews
Great!!!
Clever and senitiv machine! The app os easy and good!
Well packaged, it's so soft, rubbery, flexible, comes with a charging cable. It's charging right now so I'll test it and let you know, but it looks very decent.
very car
Received without problems, simple packaging. The product is very good, although a bit demanding, it cannot be worn for a long time, one must be very attentive to the posture of the sword.
Buying from a shop you have not heard of
That is a fair hesitation, so here is the part most shops leave vague: exactly what you are covered by, and exactly who you are buying from.

Wear it for the full 90 days from delivery. If your back is no better off, email us and we refund the purchase price in full. No restocking fee, and you do not need to have kept the box.
