“I sit at a desk nine hours a day and by four o'clock I am folded over the keyboard like a question mark. This does not force you upright, it just keeps a light pull on the shoulders so you notice the second you start slouching. Two weeks in and I catch myself sitting up without it.”

Pick your size from your height, weight and chest measurement. If you are between two sizes, or you are broad through the shoulders, take the larger one. Measure your chest by wrapping a soft tape around the fullest part, under the arms, level and snug. The elastic stretches to fit, so it should sit firm and easy to breathe in, never tight.

“I bought it for the school run and the desk and I honestly forget it is on. Slips on over my head in about four seconds, no buckles to fight with, and it sits flat enough that nobody has noticed it under a jumper.”
Renee P.Customer experience“I am six foot two and 215 pounds and the XL fits the way the chart said it would. The shoulder straps are wide so there is no digging in, and the mesh part actually breathes. Wore it under a work shirt for a full shift with no rub marks.”
Danny R.Customer experience“Comfortable and easy to wear, and it does make me stand taller at the counter. I went between sizes and took the smaller one first, which was too snug. The larger size was right, so take the size up if you are on the line.”
Ify A.Customer experience“Three of us at the office ordered them after mine turned up. The thing I like is there is nothing to adjust. You pull it on and it stays where you put it all day, and it comes off just as fast when I get home.”
Tom B.Customer experience“I wear mine over a t-shirt in the morning while I do the housework and under a blouse at work. It is light, it washes fine by hand, and the elastic has not gone slack after a month of daily wear.”
Sandra M.Customer experienceFrequently asked questions
Here is what people want to know before they order.
How do I pick my size?
Use the chart on this page. It runs S to XXL against your height, your weight and your chest measurement, and all three should point at the same size. If you are between two sizes, or you are broad through the shoulders, take the larger one. The elastic stretches to fit, so it should feel firm and easy to breathe in, never tight.
Can I wear it under my clothes?
Yes. It is a slim one-piece band that sits flat across the shoulders and the upper back, so it disappears under a t-shirt, a shirt, a blazer or a sweater. Plenty of people wear it over a t-shirt at home and under a shirt at work.
Is it complicated to put on?
No. Slip your arms through the loops, pull it up over your shoulders and you are done, usually in under ten seconds. There are no buckles, no hooks and no straps to tighten, so there is nothing to readjust once it is on.
How long should I wear it for?
Start with a shorter stretch, around thirty minutes to an hour, and build up as it starts to feel normal. It is designed for everyday comfort rather than all night, so take it off before bed and stop wearing it if anything feels uncomfortable.
