Why it matters
Where the slouch shows up
Hover or tap a point to see what changes when you stay upright.
Neck and shoulders
When your head drifts toward the screen, your neck and shoulders carry the load. Sedriva notices the drift before you do.
Rounded shoulders
Hours at a desk pull the shoulders forward. A short buzz is your cue to open the chest and pull them back.
Mid back
The slouch usually starts in the middle of the back. That is exactly where the sensor reads the change in angle.
Lower back
Sliding down in your chair flattens the lower back. Sedriva reminds you to reset your seat, not just your shoulders.
Inside Sedriva
Built small. Engineered smart.
One sensor, one job: catch the slouch before it becomes a habit.
A sensor that knows the difference
Sedriva reads the angle of your back and reacts the moment it changes. No counting, no guessing, nothing to check on a screen.
Gentle vibration
A soft buzz, not an alarm. Only you feel it.
USB rechargeable
Charge with the included cable, then go cordless.
Light enough to forget
ABS shell with a soft silicone band that flexes as you move.
Fits how you fit
Flexible construction adapts to different body sizes.
How it works
Three steps, then you forget it's there
No app to set up and nothing to learn. Charge it, wear it, and let the reminder do the rest.
Charge it
Plug in the included USB cable. Once it is topped up, the cable goes back in the drawer.
Wear it
Rest it around the back of your neck so it sits flat on your shoulders. Nothing to tighten.
Feel the reminder
Slouch and it buzzes. Straighten up and it stops. That is the whole routine.
What to expect
Posture is a habit. Here's how it builds.
Everyone is different, but this is the pattern most people describe once they start wearing a reminder.
Day 1
You find out how often you slouch
The first day is the eye-opener. Most people are surprised by how many reminders they get before lunch.
Week 1
The reminders start to space out
You begin catching yourself before the buzz. The device turns into a backstop rather than a metronome.
Month 1
Upright starts to feel normal
Sitting tall stops being something you do and starts being how you sit. Keep it on for the long days.
Compare
Sedriva vs. a basic posture brace
A strap holds you in place while you wear it. A reminder teaches you to hold yourself.
| Feature | Sedriva | Basic brace |
|---|---|---|
| Detects when you start to slouch | ||
| Reminds you in the moment | Vibration | Passive strap |
| Trains you to hold yourself up | ||
| Discreet under a shirt | Usually bulky | |
| Rechargeable, nothing to replace | N/A |
Comparison against typical passive posture braces. Sedriva is a training aid, not a medical device.
Good to know
Questions people ask
It is lightweight and the silicone band flexes with you, so most people forget it is there. Start with a couple of hours a day and build up from there.
The product measures 4.9 in (12.5 cm) wide and 4.7 in (11.9 cm) tall.
Yes. It sits flat against your back, so it works under a shirt, a hoodie or a jacket.
A USB cable is included in the box. Plug it in, let it charge, then use it cordless for the rest of the day.
One Sedriva corrector, one USB charging cable and a user manual.
