Measure round your natural waist and use the waist column. Between two sizes? Take the larger one — the band adjusts down but not up.
S and M are the smallest sizes the maker offers; check the weight range before choosing them. For XXXL, message us and we will confirm the measurements before you order.
The problem
Nobody decides to slouch. It happens in millimeters.
The screen pulls your chin forward. Your shoulders follow. You find out at 5pm.
How it works
Three parts, one job
Keep the reminder gentle enough to wear for hours.

Wide and foam-lined. Sit outside the bra line.
Spreads the pull. Mesh center so it breathes.
Two front tabs. Loosen a notch after lunch.

Before you buy
Which size do I order?
Which size do I order?
Measure your waist and use the table in the Size guide above rather than guessing from the letter — this brace is sized by measurement, not by US clothing size. If you are between two, take the larger one; the waist band adjusts down but not up.
How long should I wear it each day?
How long should I wear it each day?
Start at 20–30 minutes for the first few days, then build up to one or two hours. Published guidance on posture braces recommends a few hours a day at most — the goal is training your own awareness, not leaning on the brace permanently.
Will it show under my clothes?
Will it show under my clothes?
Under a sweater, sweatshirt or blazer it does not show. Under a thin fitted t-shirt you will see the outline of the shoulder straps if you look for it, so most people wear it over a base layer rather than against the skin.
Will it fix my posture?
Will it fix my posture?
It holds the reminder while you are wearing it, and most people feel the difference on day one. It will not rewire years of desk habits on its own — no brace does. Wear it through your worst hours and add a few minutes of upper-back strengthening and it becomes a habit rather than a prop.
Can men wear it?
Can men wear it?
Yes — it is unisex and sized by waist measurement. Men typically take one size down from the women’s equivalent shown in the size guide.

Thirty days to decide
Your back shouldn’t be the thing you notice most at the end of a working day. PostureOn gives you the nudge — a steady pull across your shoulder blades that reminds you where upright is, for the hours that matter most.
