Long sitting days can quietly wear down your upper back.
Not because your posture is bad, but because the same muscles end up working for hours.

There’s nothing to force or consciously hold. It works in the background while you focus.
Slim, low-profile, and easy to wear under clothing.
Designed to fit into real routines without adding more effort to your day.

Less neck and shoulder tension
I’ve been using Postra for 20 minutes twice a day and noticed an amazing difference within just a couple of days. I feel far less pressure in my neck and upper back, and it’s made a big difference to my stress headaches as well.
Exceeded expectations
I’ve suffered from lower back, neck, and shoulder pain for years. Since using Postra, I’ve had no pain at all. I put it on every morning for 20 minutes, and I’m pain-free for the rest of the day. After using it consistently for a week, I’ve noticed I don’t even need to wear it every day anymore. I’m sitting up straighter naturally and feeling completely pain-free. I would totally recommend it.

Why most posture tools fall short
Most posture tools rely on reminders, alerts, or tight correction. They beep, buzz, or dig in, which works briefly, then gets ignored or uncomfortable. Many are poorly made, lose shape over time, or feel restrictive enough that people stop wearing them altogether. Relief is usually temporary, and progress depends heavily on willpower rather than real support.
The POSTRA difference

Soft, durable materials that don't dig into your arms or rub your skin.
Designed to blend in.
Clean, low-profile design that fits naturally into your day.
Doesn't nag you.
No alerts, buzzers, or posture policing.
Don’t settle for posture tools that rely on discomfort or discipline. Postra is designed to support your body when it needs it most. Simple, comfortable, and built to fit into real life.
Got a question?
How long should I wear it for?
How long should I wear it for?
You don’t need to wear it every day or for long periods.
Start small, even 10–15 minutes, and only increase when it feels natural.
Your body adapts gradually, so gentle consistency works better than “all or nothing.”
Will it dig into my armpits?
Will it dig into my armpits?
No. The straps sit just below the armpit.
They shouldn’t rub or dig in. If it feels tight, loosen it a little and let it rest naturally on your shoulders.
With the right fit, it feels supportive and easy to wear.
Can I wear it under clothing?
Can I wear it under clothing?
Yes, you can. It’s slim and designed to blend in.
You might feel it a little at first, but most people forget they’re wearing it after a few minutes.
Start with a loose tee or jumper until you find the fit that feels the most natural.
Will this actually fix my posture?
Will this actually fix my posture?
It helps you hold a healthier position by guiding your shoulders back and reducing the habits that pull you forward.
It’s not a medical device and it won’t “fix” everything on its own, but it does make good posture easier to maintain.
The real progress comes from small daily habits plus gentle, consistent use.
Most people notice they sit and stand straighter without thinking about it after a few weeks.
