Why It Doesn't Tip When You Push It with Your Foot — The Hidden Engineering of the LC99 Base
Summary Most footrests tip or slide when you push them with your foot. The LC99 solves this with three design principles: a 512mm wide base, TPR non-slip pads, and a low center of gravity. It stays stable under pressure, yet moves smoothly when you want to reposition it. Why Footrests Keep Sliding Away You place a footrest under your desk, use it for a while, and then — it's slid out of position again. You pushed it with your foot without thinking, or it shifted when you changed positions. When... Read more...
Do Footrests Really Make a Difference? — 5 Research-Backed Facts About Their Effects
Do footrests actually work? "Isn't it just something you put your feet on?" Here are 5 research-backed answers. The bottom line: footrests reduce lower limb fatigue by 23% and can lower lumbar disc pressure by up to 15%. 1. 23% Reduction in Lower Limb Fatigue — When Your Feet Are Supported, Your Legs Rest A 2019 study published in Ergonomics found that participants using a footrest experienced 23% less lower limb fatigue compared to those without one. Researchers attributed this to the reduction of static load on lower body muscles... Read more...
How Far Has the Chair Evolved? — From Beanbags to AI Smart Chairs, and What's Still Missing
Over the past two decades, the office chair has never stopped changing. Cubicles gave way to beanbags. Beanbags gave way to standing desks. And now, sensors and AI can read your posture in real time through a smart chair. The ergonomic chair market reached $10.4 billion in 2024. But right now, at this very moment — where are your legs? Why Google Gave Up on Beanbags In 2003, the Googleplex opened its doors. Beanbags, slides, free cafeterias, nap pods. The experiment was to build not a place to work, but... Read more...
Same Chair, Different Back Pain — The Real Difference Is Your Foot Position
In any office, two people can use the identical chair and desk — yet one walks away at the end of the day rubbing their lower back, while the other stands up effortlessly. If the chair were the problem, everyone would hurt equally. But that's not what happens. The difference isn't made by the chair. It's made underneath the chair — specifically, by where your feet are. 80% of Your Sitting Posture Is Determined by Pelvic Tilt Research on lower back pain consistently points to one key variable: pelvic tilt....

Why Silver Film? — The Heating Technology Behind the LC99 Heat
Why Silver Film? — The Heating Technology Behind the LC99 Heat If you've ever worked at a desk with cold feet, you know how distracting it can be. ROUMO chose silver — the most thermally conductive metal on earth — to solve this everyday problem. Here's why. Cold Feet Are More Than Just Uncomfortable Even in heated offices, the floor-level temperature is often 5–10°C lower than at desk height. Warm air rises; cold air sinks. Your feet bear the brunt of that difference. A study by Cornell University found that... Read more...
What Happens to Your Legs After 8 Hours of Sitting? — 3 Studies Reveal the Truth About Lower-Body Circulation
An average of 7.7 hours. That's how long office workers spend sitting in a chair each day. But what exactly happens to your legs during those hours? If you think it's just "a little stiffness," the research tells a more serious story. Today, we break down 3 studies that reveal what prolonged sitting does to lower-body blood flow — backed by real data. Study 1. After Just 10 Minutes, Vascular Function Declines Researchers at the University of Missouri (Padilla & Fadel, 2017) conducted a comprehensive analysis of how prolonged sitting... Read more...
Your Back Pain Isn't a Back Problem — What the Kinetic Chain Reveals About Your Feet and Spine
When your back hurts, you try to fix your back. But the real starting point of the problem might be your feet. Kinetic Chain theory explains that your feet→ankles→knees→pelvis→spine function as a single interconnected chain. When the bottom of the chain (your feet) is unstable, everything above it — all the way up to your lower back and neck — collapses. Research shows that using a footrest reduces lumbar disc pressure by 10–15%, supporting this very connection. What Is the Kinetic Chain? The kinetic chain is a biomechanics concept describing...
