You’ve heard of firmness, softness, and even “sleep numbers”—but have you ever heard of interface pressure?

This little-known but powerful metric may be the missing link between restless nights and truly restorative sleep. At Pressure’s Off, interface pressure is at the core of our mattress innovation—and once you understand it, you’ll never think about sleep the same way again.

What Is Interface Pressure?

Interface pressure refers to the amount of force between your body and the surface you’re lying on. More specifically, it’s the pressure applied to your skin and underlying tissues by the mattress beneath you. Certain parts of the body—like the shoulders, hips, and lower back—bear more weight and thus experience higher pressure levels.

High interface pressure may seem harmless, but it silently affects your body all night long.

Why It Matters: The Pressure Problem

When certain parts of your body are under sustained high pressure, blood flow within the capillaries can be restricted. In response, your body instinctively shifts positions to relieve that pressure—often without you even realizing it.

These subconscious movements, while necessary to protect tissue health, disrupt sleep cycles. You may not remember tossing and turning, but your brain does—losing out on vital time in deep and REM sleep.

In fact, clinical studies show that many people change positions up to 40 times per night due to pressure-related discomfort. That’s 40 micro-awakenings—each one chipping away at the restorative power of your sleep.

Firmness Isn’t the Fix

Traditional mattress marketing focuses on firmness levels—soft, medium, firm. But here’s the catch: firmness is subjective and doesn't necessarily correlate with healthy sleep. What one person finds comfortable, another finds painful.

That’s where interface pressure is different. It’s an objective measurement—quantifiable, testable, and independent of preference. And it’s the foundation for our technology at Pressure’s Off.

Our Solution: Pressure-Aware Design

Over 40 years of research have gone into designing the Pressure’s Off mattress. Through clinical studies, pressure-mapping sensors, and real-world testing across diverse body types, we’ve learned how to evenly distribute pressure across the entire sleeping surface.

Our proprietary EqualEase technology ensures that no single part of your body bears more stress than it should. Meanwhile, SmartContour layers dynamically adapt to your shape, allowing key areas like shoulders and hips to gently sink, preserving spinal alignment while reducing pressure build-up.

The result? Fewer movements. Longer, deeper sleep cycles. And a noticeable difference in how you feel when you wake up.

The Future of Sleep, Measured Scientifically

As the science of sleep advances, interface pressure is emerging as a more meaningful benchmark than subjective comfort. It’s a metric that explains why you’re tossing and turning—and what needs to change to stop it.

At Pressure’s Off, we’re proud to lead the charge in pressure-based sleep innovation. Our goal isn’t just to build a better mattress. It’s to give you better sleep, backed by measurable science.
