The real problem
Why your back hurts by 5pm
Hours hunched over a desk train your spine to stay slumped. By the afternoon your upper back aches, your neck stiffens, and slouching becomes your default — even when you stand up.
😣
Dull ache between the shoulder blades by afternoon
🦴
Stiff neck and tension headaches from forward head posture
🪑
Slouching feels “normal” — even when you try to sit up
😴
Low energy and shallow breathing from a collapsed chest
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.

I'm a nurse on 12-hour shifts. By week two I stopped getting that knot between my shoulder blades.

Skeptical at first. Now my wife says I look two inches taller in photos. Sold.

The 14-day guide actually made the difference — five-minute resets I can do between standups.
Real stories, real change
★★★★★
I sit for 10 hours a day as a developer. This device single-handedly saved my upper back — the end-of-day ache is just gone.
★★★★★
After my second pregnancy I rounded forward constantly. Posa gave me the little nudge I needed to stand tall again.
★★★★★
I bought it for the gym but wear it at my desk now. The buzz is genuinely gentle — not a shock, just a reminder.

🎁 Included free
Free digital bonus, included with every kit
Every Posa ships with the Posture Blueprint & 14-Day Ergo Guide — short, practical, and built to make the habit stick.
What if I only have 5 minutes a day?
+
That's all you need. The guide is built around micro-routines — short resets you can do between meetings to undo hours of sitting.
How does proper posture reduce back tension so fast?
+
When your spine stacks correctly, the load moves off strained muscles and onto your skeleton. The guide shows you exactly how to find — and hold — that aligned position.
Do I need any equipment?
+
No. Every routine in the guide uses just your body and your Posa. No gym, no mat, no extra gear.

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. Most wearers say no one ever notices it.
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?
+
Many people feel less tension within the first week or two as the gentle reminders help them sit and stand taller. Building a lasting habit 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.
