How Much Difference Do Bed Roller Pressure Settings Make? A Practical Load Test
TL;DR
A practical mechanical test of Movelio Bed Roller, carried out with a 110 kg test person using the S-Roller on the lower back, measured 12.4 kg of load through the roller at the lowest setting and 76 kg at the highest.
That is a 6.13× difference, corresponding to an approximately 513% increase in measured roller load from the lowest to the highest setting.
One of the main ideas behind Movelio Bed Roller is adjustability. The goal is not to provide one fixed sensation, but to let the user control how much load is transferred through the roller.
But how much difference do the lowest and highest pressure settings make in practice? We decided to measure it.
How we performed the test
To simulate the Bed Roller geometry during normal use, the roller was placed directly on a weighing scale. The top of the scale was positioned at the same height as all four wheels, allowing the frame to remain level.
We then recorded how much load was transferred through the roller at different frame settings. Both the I-Roller and S-Roller were tested. This article focuses on one of the clearest comparisons: a 110 kg test person using the S-Roller on the lower back.
The test was conducted with Movelio Bed Roller. Bed Roller Professional uses the same pressure-adjustment system: the same gravity-based principle, I-Roller and S-Roller, frame geometry, six height levels per side and 36 pressure and angle combinations. The measured load difference therefore applies to both models, even though Bed Roller was the model physically used for the test.
Important test note
The 110 kg test condition is a measurement setup, not a recommendation that overrides the stated user limits. Movelio Bed Roller for home use is specified for users up to 100 kg. Bed Roller Professional is specified for users up to 130 kg. Always follow the limit for the model being used.
The values—12.4 kg, 76 kg, 6.13× and approximately 513%—were measured with Bed Roller. Because Bed Roller Professional has the same pressure-adjustment geometry and roller system, the measured difference also applies to Bed Roller Professional. Individual results will still vary with the user, body area, position and setup.
From 12.4 kg to 76 kg of measured load
Practical Bed Roller test result for one 110 kg test person using the S-Roller on the lower back. Individual results will vary.
From the lowest to the highest setting, the measured load through the S-Roller increased by approximately 513%.
For the user, this means the highest setting transferred more than six times as much body weight through the roller in this test. It shows how widely the massage intensity can be adjusted—from relatively gentle contact to substantially higher mechanical load.
Why can the difference be so large?
Adjusting the frame does more than move the roller slightly up or down. It changes how the body is supported and how much body weight is transferred through the roller rather than the surrounding support surface.
At a lower setting, more of the body remains supported elsewhere. At a higher setting, substantially more load can be transferred through the roller. This helps explain why a limited change in frame height can produce a large change in the measured load.
I-Roller and S-Roller distribute load differently
Total measured load and local pressure are not the same thing. Two rollers can carry the same total load while feeling very different because the contact area is different.
I-Roller
Broader, more evenly distributed contact across a larger area.
S-Roller
More focused contact through two raised zones with a central channel.
The S-Roller can therefore feel more targeted and intense, while the I-Roller provides a broader and more evenly distributed sensation. The image shows the actual roller profiles; it is not a pressure map.

Why 36 pressure combinations matter
Each side of Bed Roller has six height positions. Because the sides can be adjusted independently, the system provides up to 6 × 6 = 36 pressure and angle combinations.
These combinations do more than make the experience feel “harder” or “softer”. They let the user change body position and load distribution gradually, including angled setups with different heights on each side.
Explore adjustable massage at home
Bed Roller combines 36 frame combinations with I-Roller and S-Roller, so you can begin gently and adjust the experience yourself.
More pressure is not always the goal
The highest setting is not automatically the best setting. The purpose of the wide adjustment range is control.
A new user may prefer to begin gently. Different body areas may call for different loads, and the same setting may feel different from one day to the next. Increase gradually, remain in control and reduce the setting if the sensation becomes uncomfortable.
If you are unsure where to begin, Movelio Companion App can guide you on body area, roller choice, starting pressure, duration and frequency—while you remain in control of every setting.

What exactly did we measure?
The weighing scale measured the load transferred through the roller. It did not directly measure pressure inside muscles or other tissue.
In physics, pressure is force divided by area. Actual contact area varies with body shape, position, roller type and load. For that reason, this practical test should not be interpreted as a clinical or medical study.
It demonstrates a mechanical point: changing the Bed Roller setup can substantially change the amount of load transferred through the roller. Results will vary between users and setups.
The result at a glance
Tested model: Movelio Bed Roller
Test condition: 110 kg test person, S-Roller, lower back
Lowest measured roller load: 12.4 kg
Highest measured roller load: 76 kg
Highest compared with lowest: 6.13×
Increase from lowest to highest: approximately 513%
The difference between settings is therefore not only theoretical. In this test, changing the setup produced a substantial difference in measured roller load. Combined with the contact characteristics of I-Roller and S-Roller, this gives users a broad range of ways to adjust the experience.
Frequently asked questions
How much did the load change between the lowest and highest settings?
For the stated test condition, measured load increased from 12.4 kg to 76 kg. The highest value was 6.13 times the lowest, an increase of approximately 513%.
Does a 513% increase in roller load mean 513% more pressure in the body?
No. The scale measured total load through the roller. Local pressure also depends on contact area, body position, body shape and roller type.
Which feels more focused: I-Roller or S-Roller?
S-Roller provides more focused contact through two raised zones. I-Roller spreads contact more broadly and evenly.
Is the highest pressure setting always best?
No. The value of the system is adjustability. Begin gently, choose a setting that feels appropriate and increase only when you remain comfortable and in control.
Choose the Bed Roller for your setting
Bed Roller is designed for personal use at home. Bed Roller Professional is built for frequent use by multiple people in clinics, gyms and workplaces.
Practical test limitation: This was not a clinical study. It was a mechanical comparison under the described conditions. Measurements may vary with the user, body area, position, roller and setup.
