What exactly does the sleep ergonomics simulator measure?

The sleep ergonomics simulator records two things at the same time. Sensors in the measuring mattress measure how your body pressure is distributed across the entire mattress surface. A depth camera also records your body shape when you lie on your side and back, including your shoulder and pelvic width, contours and proportions. The sleep ergonomics simulator calculates your individual sleep ergonomics profile from both data sources. It shows where your body needs support or pressure relief — the basis for building your mattress.

How long does the measurement take?

The measurement itself only takes a few minutes. It is part of the sleep ergonomics analysis, which also includes the conversation with your sleep advisor, going through the results together and the rest-test. So plan a little more time for the whole appointment.

Do I need to prepare for the measurement?

No. You are measured in your everyday clothes and don’t need to change or prepare. Just bring along what you notice about your sleep, for example whether you wake up tense in the morning or often change position at night. These details help your sleep advisor interpret the readings correctly.

What happens to my readings?

Only the readings needed to set up your mattress are stored. They allow you to be measured again within ten years, for example if your body has changed. Your mattress can be adjusted at any time, because it is built in modules.

Is the measurement a medical examination?

No. The sleep ergonomics simulator measures how your body lies and is used to set up your mattress for you. It does not replace a medical examination or diagnosis.

Why isn’t it enough to simply rest-test a mattress?

In a typical rest-test, the first impression decides, and it is often misleading. It can’t reliably tell you whether a mattress supports your body properly. That’s why the sleep ergonomics simulator measures first, and your sleep advisor sets up your mattress according to the readings. Only then do you try it out. For us, a rest-test means more than just trying: during the appointment, your sleep advisor checks whether all ergonomic criteria are met, such as spinal support, zone allocation, shoulder position and waist support, in different sleep positions and with the right pillow.

How much does a sleep ergonomics analysis with the sleep ergonomics simulator cost?

Nothing. The advice and the sleep ergonomics analysis on the sleep ergonomics simulator are free of charge. You find out how you lie and what your mattress needs to do. Then you decide in your own time.

Where can I find the sleep ergonomics simulator?

You’ll find the sleep ergonomics simulator in our centers and partner stores. Body pressure measurement is part of every sleep ergonomics analysis. The additional 3D capture of your body shape is currently being introduced step by step. When you book your appointment, you’ll find out whether it is already available at your location.

The ProSim4D
sleep ergonomics simulator

Developed by the Proschlaf® Institute and recommended by sleep researchers: the patented sleep ergonomics simulator measures how your body lies in just a few minutes. This creates a mattress that supports and relieves pressure exactly where you need it.

Why measure?

Measure instead of guess.

You can tell straight away whether a mattress feels good. But you often notice only much later whether it supports your body properly. That takes an objective measurement, independent of anyone’s opinion — yours or ours. That’s exactly what the sleep ergonomics simulator is for.

Objective.
The sleep ergonomics simulator records how your body actually lies. Your mattress is based on readings, not assumptions.

Patented.
At its heart is the patented measuring mattress with a pneumatic unit, developed by the Proschlaf® Institute in Salzburg.

Straightforward.
The measurement takes just a few minutes. You stay in your everyday clothes, with no preparation needed.

Personal guidance.
Your certified sleep advisor guides you through the measurement and explains what the results mean for you.

How the sleep ergonomics simulator measures

Four dimensions. One sleep ergonomics profile.

The ProSim4D sleep ergonomics simulator records your body in four dimensions: the three spatial dimensions of your body shape and the pressure your body exerts on the mattress. Only together do they show how you really lie.

Body pressure:Sensors in the measuring mattress record how your body pressure is distributed across the entire mattress surface. This shows where your shoulders and pelvis sink in, and where your body needs support or pressure relief.
Body shape:A depth camera moves over you and records your body shape when you lie on your side and back, just as you actually lie. Your shoulder and pelvic width, contours and proportions are determined automatically.
Sleep ergonomics profile:Both data sources are combined. The pressure shows what happens between your body and the mattress; your body shape shows why. From this, the sleep ergonomics simulator calculates your individual sleep ergonomics profile.

From sleep ergonomics profile to mattress

Calculating is good. Feeling is better.

Your sleep ergonomics profile doesn’t stay on a screen. During your appointment, your sleep advisor builds your mattress to match your readings, zone by zone. While you rest-test it, they check that it meets all the ergonomic criteria before your mattress is made.

This is possible because our mattresses are modular and not glued:

Support elements in the base core, matched to your sleep ergonomics profile
Top layers above the base core, in different materials and firmness levels to match your personal feel
Made in Austria to this exact configuration

Many people have their aha moment on the sleep ergonomics simulator: there’s a world of difference between lying down and lying really well.

How the measurement works

The simulator measures. Your sleep advisor understands.

The sleep ergonomics simulator provides objective data. But it can’t ask questions. Your sleep advisor will talk with you about how you sleep, what wakes you at night and what could change. Here’s how your measurement works:

Understanding:Your sleep advisor asks about your sleep, your everyday life and your needs. Then they calibrate the sleep ergonomics simulator and explain what will be measured.
Measuring:First, you lie on your side, then on your back, and simply relax. The measurement takes just a few minutes.
Reviewing:You look at your results together.
Building:Your sleep advisor builds your mattress to match your sleep ergonomics profile, zone by zone.
Rest-test:You lie on your configuration while your sleep advisor checks that it meets all the ergonomic criteria, from spinal alignment to the right pillow.

More than a pressure measurement

The sleep ergonomics simulator compared

Other providers also take measurements when you buy a mattress. But the measurement methods commonly used on the market usually capture only part of the lying situation: sensor mats are placed on a mattress like a thin topper; other methods put the measuring technology in a slatted bed base; and some scan your body while you’re standing. The sleep ergonomics simulator takes a different approach. Its measuring technology is part of the mattress itself, and it combines body pressure and body shape in a single measurement.

“A pressure image shows exactly where pressure occurs. Only when we combine it with body shape can we understand why it occurs there. That’s exactly what the sleep ergonomics simulator makes visible.”

Research and development

From research. For your sleep.

The sleep ergonomics simulator was developed at the Proschlaf Institute in Salzburg in collaboration with medical professionals, sleep researchers and physiotherapists. For more than 30 years, the institute has researched how the body behaves during sleep: how pressure affects the body, how sleeping positions affect sleep, and how the body’s needs change over the course of life.

Developed across disciplines:Medicine, sleep research and physiotherapy all inform the measurement.
Patented technology:The measuring mattress and its pneumatic unit are patented.
Award-winning:Received the Innovation Award of the Province of Salzburg in 2009.

“How well we sleep also depends on how we lie. The sleep ergonomics simulator makes this lying situation measurable, instead of leaving it to how it feels.” — Hans Malzl, sleep researcher and inventor of the sleep ergonomics simulator

At the heart of the schlafTEQ method

Since receiving its award, the sleep ergonomics simulator has been continually developed, most recently with the addition of 3D body-shape recording. Its calculations are now based on more than 25,000 measurements, and every sleep ergonomics analysis adds to this database.

Few measurement methods on the market have a data and experience base of this size. In the DACH region, the sleep ergonomics simulator is the most widely used tool for sleep ergonomics analysis for fully customised mattresses.

It is the central element of the schlafTEQ method:

Advice:Your sleep advisor gets to know you and your sleep.
Measurement:The sleep ergonomics simulator objectively records how your body lies.
Lie well:Your mattress is built to match your readings.
