It's like an Apple Watch, but for your spine.
Traditional braces hold your shoulders back for you, so it's easy to come to rely on them. Postuven uses gentle haptic feedback to prompt you to sit tall yourself — training the habit, not forcing it.

The Posture Problem
The hidden toll of the desk slouch
60 lb
Load on your neck
Tilting your head forward to look at a screen can place an estimated load of up to ~27 kg (about 60 lb) on the cervical spine, compared with 4–5 kg in a neutral position.

8+ hrs
Spent seated each workday
Many desk workers spend eight or more hours a day seated, much of it leaning toward a screen — which makes the slow slouch easy to fall into and hard to notice.

Brilliant little gadget that reminds me during work about my posture through buzzing. Simple design, great value.
A great device, so easy to use and sense. Works very well, let's get in better health with this product wearing it all day.
Great item! Works perfectly, highly recommend. I'll be purchasing another for my son!
Works as described to correct your posture — when you slip out of position it reminds you to sit up properly.
Works well. I use it while working from home to stop myself slouching.
Works well and is very helpful for its purpose. One small improvement would be a few seconds' delay so not every movement triggers it.
Why We Built It
Born out of frustration with the desk slouch
Like a lot of people, we spend most of the day at a desk — and we felt it. By mid-afternoon, necks were tight and shoulders had crept forward toward the screen.
We tried traditional back braces, but they were hot and restrictive, and posture tended to slump straight back down once they came off. They did the holding for us, rather than helping us build the habit ourselves.
So we set out to make something different: a lightweight, strap-free trainer that gives a gentle nudge when you slouch — more like a quiet coach on your back than a cage around it.
