Know before
you feel it.

Your body changes before you feel it. Three sensors read those changes through full contact with both thighs when you just sit, and compare them with your own normal. This is how.

01

Your body moves first.

Before an injury announces itself, the body compensates. Heart rhythm shifts. Recovery slows. One leg quietly starts carrying more load than the other. These changes are small, but they are measurable, and they show up weeks before pain does.

Three signals, read together.

Each sensor sees something the others miss. Because they record the same heartbeat at the same instant, they can check each other, and the algorithms can tell a real shift from a noisy morning.

Contact area matters. A wrist strap reads through a few square centimetres of skin. The seat reads through both thighs at once, with your seated weight pressing the signal into the sensors.

Sit. Lock. Read. Stand.

1You sitBioID recognises you from your own signal signature. Guests are never measured.
2Signals lockECG, PPG and BCG align beat for beat. Load cells log seated weight and balance.
3ReadingEnough clean beats for heart rate, HRV, SpO₂, respiration and blood pressure trends.
4PowerThe four load cells time the push. Sit-to-stand power in W/kg.
Then it compares today with you.

Not with a population average. Every reading is set against your own baseline, built from your first weeks of sits. When something moves outside that band for long enough, you and whoever you've chosen get a heads-up: get it checked.

Install it, connect it, then just sit.

The Casana Pro installs just like any other toilet seat. No plumber required. Most people complete installation in a few minutes with basic tools.

Fitting the Casana Pro to a toilet with the two standard bolts
1Install

Two standard US toilet bolts, 5.5 inches apart centre to centre. Elongated toilets only. Check yours first.

2Connect and register

A simple setup connects the Seat to your home Wi-Fi. Register up to five people; BioID recognises each from their own signal signature.

3Everyday use

Just sit. Readings appear in the Companion App on iPhone, Android or the web. There is no screen and no camera on the Seat.

Living with the Casana Pro

Batteries
Battery powered, no charging. The battery should last several years; Casana sends new batteries as needed.
Cleaning
Clean it like a normal toilet seat, without abrasive materials.
Guests
Guests use the Seat normally. It won't calculate readings for anyone who isn't registered.
