Sestala corrects the force ceiling in its own published standard

Europe, 3 September 2026 - Sestala today corrected the single number at the centre of its own published safety standard: the force ceiling every machine in its network must hold to is 70 newtons, not the 100 newtons stated in the company’s release of 20 August. The correct figure has stood on Sestala’s safety pages throughout; the 20 August release carried the wrong one. The number governs the hardest any Sestala machine may ever press, in every market where the company operates.

The ceiling itself has not moved. It sits in the machine’s safety layer, not in a setting a person or the session software can raise: force above 70 newtons, roughly the pressure of a seven-kilogram weight at the firmest of the ten levels a member can choose, is refused outright. The thermal ceiling stays at 40°C at the contact surface, the stop control still halts motion within 450 milliseconds and stays halted until the person on the table says otherwise, and the neck remains excluded from the motion path entirely. None of the underlying engineering changed; only the number printed in the 20 August release was wrong.

Sestala publishes the figure at all because no European standard sets one for a machine built to touch a person on purpose, repeatedly, by design. EN ISO 13482:2014 requires a maker to derive and validate its own limit rather than supplying one. A number published to fill that gap is only useful if it is exact, which is why the company is issuing a correction rather than quietly editing the earlier page.

“A number we are asking a partner, an insurer or a regulator to check against has to survive being checked against us first,” said Jörg Olbing, founder. “We published 100 newtons by mistake three weeks ago. It is 70, it has always been 70 in the machine, and we would rather say so plainly than let two numbers sit on our own site at once.”

The numbers, for reference:

• Force ceiling: 70 N, fixed in the machine’s safety layer, never a user or software setting
• Comparison: roughly 7 kg at the firmest of the ten pressure levels a member chooses
• Thermal ceiling: 40°C at the contact surface
• Stop response: motion ceases within 450 ms of the stop control; the machine stays stopped until the person on the table says otherwise
• Motion path: no cervical or neck work, enforced in the machine’s hardware geometry
• Markets: Germany, Switzerland and the United Kingdom; first studios open 2027

Sestala builds and runs precision recovery - machine recovery sessions delivered to a standard its founder would lie down on himself.
