The way you used to stand
A carefully-chosen shoulder strap, an honest twenty minutes a day, and the four-week Method to make it stick.

Every posture corrector we found looked like it belonged in a hospital
"I don't feel old. I just don't want to look at a wedding photograph and see somebody else's posture in mine."
Worn under a shirt, not over a life.
A one-millimetre profile in brushed cotton. Invisible beneath linen, cotton, or your favourite blouse. Nobody will know but you.
No armpit chafe. The category's quiet failure, solved.
We chose this strap specifically because it doesn't dig where every other posture corrector does. It is wide, brushed-cotton, and bevelled at the edge. You'll forget you're wearing it by nine.
A four-week Method, then put it in a drawer.
Twenty minutes a day, for four weeks. The Method is yours forever: printable workbook, daily morning email. By Sunday of week four, the Corrector retires. The way you stand stays.
A simple object, chosen carefully.
The Corrector is one object, in seven sizes from XS to XXXL. We chose it for the strap, the weight, the discretion under a shirt. The four-week Method, the workbook, the daily email prompts: these are what we made to go with it.

Brushed-cotton strap
Wide, breathable, finished with a softened edge. Forgets the underarm exists. The one feature competitors quietly fail at.
One-millimetre profile
Knitted in a two-layer construction that disappears beneath a cotton shirt. Wear it to brunch. Wear it to a wedding.
Sculpted lower-back panel
The Corrector encourages the upper back to open, then quietly steps out of the way. Never a brace. Always a reminder.
One seam, no hardware
No buckles, no plastic clips, no clinical edges. Adjusts with a single fabric pull. Lays flat on a folded shelf.
Four weeks. Then it lives in a drawer.
Each Corrector ships with the printed four-week Method card. The full Method: a 28-page PDF guidebook and one short morning email each day. It arrives in your inbox within minutes of ordering. The Corrector is the metronome; the body learns the rest.
Notice.
Twenty minutes each morning, while the kettle heats. You will catch yourself catching yourself.
Soften.
The shoulders begin to release. We add four standing minutes, by an open window.
Strengthen.
Three small movements a day. The Corrector reminds. The body remembers more than you'd think.
Graduate.
By the end of week four, you'll wear the Corrector twice. Then once. Then it lives in its drawer.As needed
The honest sheet.
Everything we'd tell a friend before they ordered. Everything we'd want to know before we did.

You will probably ask these.
Is this a medical device?
No, and we don't pretend it is. The Corrector is a posture-training tool: a wearable reminder, paired with our four-week Method. If your back is in active treatment, please ask your physiotherapist before beginning.
Can I wear it under a shirt?
Yes. This is the brief we designed against. The Corrector sits at one millimetre beneath a cotton or linen shirt and disappears under a knit. Several owners have worn it to weddings without anyone noticing.
How long do I wear it each day?
Twenty minutes is the protocol. Some owners wear theirs longer in week one; we'd quietly suggest you don't. The point is not the wearing. It is the noticing.
Will it hurt under the arms?
It is the question we are asked most, and the question that drove the brushed-cotton strap. If by week one it does, contact us and we'll send a different size at no charge.
What is the 30-night guarantee?
Wear the Corrector for thirty mornings. If by the end you'd rather not have it, email us at info@getlindra.com and we'll refund you in full. You can keep the Corrector. Give it to a friend or donate it. We're a small new brand and we'd rather refund you than make you pay for return shipping. That's the trade we offer for being honest about being new.
How long does shipping take?
We ship free to anywhere in the world. Most orders arrive within 7–10 days. Exact timing depends on your location — Australian orders typically arrive sooner.
First reviews coming soon.
Lindra is brand new. The first owners are receiving their Correctors and beginning Week One of the Method now. Their real reviews, written in their own kitchens and in their own words, will appear here over the next few weeks.
If you order today, you become one of those first voices. There’s still time to be a Founding Member.
