The real problem

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.

🪑 You sit up straight — and five minutes later you have dropped again
😣 A dull ache between the shoulder blades by mid-afternoon
📷 Slouching feels normal, until you catch yourself in a photo
🔁 Stretching helps for an hour, then you are back where you started

How it works

1

Clip it on

Sits discreetly on your upper back — under any shirt.

2

It buzzes when you slouch

A gentle vibration — your private reminder to lift up.

3

You straighten & build the habit

Day by day, sitting tall starts to feel automatic.

Everything worth knowing before it arrives.

Questions, answered

Does it hurt when it vibrates?
Not at all. The vibration is a soft, gentle pulse — closer to a phone buzzing in your pocket than anything sharp. It's a reminder, never a shock.
Can I wear it invisibly under a tight t-shirt?
Yes. Posa is slim and sits flat against your upper back, so it stays hidden under most shirts, blouses and sweaters.
How long does the battery last?
A full charge lasts about a week of normal daily wear. It recharges quickly over USB-C, so a Sunday-night top-up easily carries you through the work week.
How fast will I notice a difference?
Most people notice the reminders doing their job within the first few days — that's the awareness part. Building a habit that holds without the buzz takes consistent daily wear over a few weeks.
What is the refund policy?
You're covered by our 90-Day Money-Back Guarantee. If you're not feeling more confident in your posture, send it back for a full refund — no questions and no restocking fees.
Ready when you are

Start sitting taller this week

Clip it on Monday morning and let it do the noticing for you. If it is not for you, send it back — you have three months to decide.
