Your mattress. Adjusted to you.
Answer a few questions about your body and sleeping position. Sleep Calibration uses your answers to calculate a personalised setting recommendation for Scal Plus or Scal Pro. You can adjust your mattress to feel firmer or softer whenever needed.
1-3 minutes
Step 1 · The frame
Two models. One question: How do you want to lie?
Just like at the optician: you only choose the frame. The strength – your setting – comes from the measurement and fits every model.
Scal Plus
by Sleep Calibration
More balance for comfort and reliable support.
Scal Pro
by Sleep Calibration
The finest tuning for maximum individual calibration.
The principle
Frame and strength. Two decisions that have nothing to do with each other.
Eyesight is measured. Blood pressure is measured. Now sleep is, too. Your calibration doesn't recommend a model – it delivers the settings for your core. And those work identically in every model.
A matter of taste
The model = the frame
Scal Plus or Scal Pro. Comfort layer, climate, cover. Needs no measurement – available right away.
A matter of measurement
The calibration = your strength
Support and pressure relief per zone, calculated exactly for your body. Before or after your purchase – you decide.
Cause instead of symptom
No tracker.
- Trackers measure symptoms: pulse, phases, lying awake.
- We measure the cause: how your body needs to lie.
- A score describes your sleep.
- A setting changes it.
- One produces data.
- The other produces sleep.
Feel free to keep your tracker. After the calibration it finally has something good to report – many of our customers see it in their own sleep data.
Zero effort
The only thing you have to do for your health: sleep.
No app. No routine. No time spent. From now on your recovery runs automatically – every night, for eight hours.
Why Sleep Calibration?
Every body needs a different level of support.
Too soft or too firm is not a coincidence - it is missing calibration.
Sleep Calibration calculates the counterpressure that fits you.

FAQ
Common questions about Sleep Calibration
The key answers worth reading before you decide on a sleep system.
Why might you not sleep optimally even with a “good” mattress?
A good mattress is not automatically adjusted correctly for your body. Body shape, weight and sleeping position determine how much support and pressure relief you need.
Conventional mattresses usually offer fixed firmness levels and predefined comfort zones. Sleep Calibration uses your information to calculate a personal setting recommendation for Scal Plus or Scal Pro. The sleep system is adjusted accordingly and can later be made firmer or softer if required.
You no longer have to adapt to the mattress – the mattress is adjusted to you.
Why is buying a conventional mattress so uncertain?
When buying a conventional mattress, you usually choose from a few fixed firmness levels. Online selection is often based on general recommendations; in a store, it is based on a few minutes of testing. Neither fully reflects how your body lies for many hours every night.
Sleep Calibration separates the choice of model from your personal setting. Your body details, weight and sleeping position are used to calculate a setting recommendation for Scal Plus or Scal Pro. The setting can be adjusted again later.
You no longer choose only by H2, H3 or feel – you choose a mattress that is adjusted to you.
Why can your sleep change even when you have changed nothing?
Even if your sleeping habits remain the same, your mattress changes over time. Continuous pressure, body heat and moisture can soften materials and alter their original support.
This can also change pressure distribution – often gradually and without you noticing at first.
Scal Plus and Scal Pro are not limited to one unchangeable firmness level. The sleep system can be made firmer or softer and readjusted to your current needs.
You can correct the setting instead of immediately replacing the entire mattress.
Why should you decide how your mattress fits you – rather than the other way around?
With a conventional mattress, you choose a model and a fixed firmness level. Your body then has to adapt to that specification – even if your weight, sleeping position or personal needs change.
With Sleep Calibration, you decide how the mattress should be adjusted to you. Your information is used to create a personal setting recommendation for Scal Plus or Scal Pro. The sleep system can later be made firmer or softer if required.
Until now, you adapted to the mattress. With Sleep Calibration, the mattress is adjusted to you.
Why is ergonomics with Sleep Calibration more than a promise?
Ergonomics should not be a vague promise – it should suit your body. Sleep Calibration combines your body details, weight and sleeping position with defined criteria for support and pressure relief.
This creates a specific setting recommendation for Scal Plus or Scal Pro. It is transferred to the sleep system, documented and can later be reproduced or adjusted.
It is more than simply “feeling comfortable” – you receive a transparent setting for your body.
Why is a durable, adjustable mattress worthwhile in the long term?
When firmness or comfort no longer feels right, a conventional mattress is often replaced completely. That costs money, creates extra effort and consumes new materials.
Scal Plus and Scal Pro are adjustable and modular. Changes can therefore often be addressed through a new setting or by replacing individual components instead of replacing the entire sleep system.
You are not repeatedly investing in a new mattress, but in a sleep system that can adapt over the long term.
How can a mattress remain hygienic for many years?
Every mattress comes into contact with body heat, moisture and skin particles night after night. Over time, these can also accumulate inside. A clean cover alone does not solve this completely.
Scal Plus and Scal Pro are modular. Depending on the selected cover and component, individual parts can be removed, cared for or replaced when required. An additional mattress protector can further reduce the penetration of moisture and impurities.
You care for or replace what is actually affected – not automatically the entire sleep system.
What do I receive after the Sleep Calibration calculation?
After you provide information about your body and sleeping position, it is evaluated. You then receive a personal setting recommendation for Scal Plus or Scal Pro.
The recommendation describes how the adjustable sleep system should be configured for you. It can be transferred to your chosen model, documented and adjusted later if your needs change.
You choose the model. Sleep Calibration provides the personal setting.
Who is Sleep Calibration particularly suitable for?
Sleep Calibration is suitable for people who want more than a fixed H2 or H3 firmness level. What matters is the desire for a mattress that is personally adjusted and can be adapted later as needs change.
This is particularly useful if body weight, sleeping position or personal comfort preferences change, or if conventional mattresses consistently feel too firm or too soft.
For anyone who no longer wants to adapt to the mattress – but wants the mattress adjusted to them.
Why does the mattress need no electricity while you sleep?
Scal Plus and Scal Pro use an air-cushioned, adjustable core. Once the sleep system has been configured, the selected support remains in place without a permanent power supply, sensors or electronic components inside the mattress.
A pump is only required when the setting needs to be changed. While you sleep, the system works without cables, an app or continuously running technology.
Personally adjusted. No electricity at the bedside.
Does every day count for you?
Then every night should be set exactly to you. Experience Sleep Calibration yourself and feel the difference from the very first night.
