The real problem isn't 'my desk is small.' It's 'my legs have nowhere to go.'
Your chair is only half. When your legs feel right, your day feels different.
Year Three of Remote Work — What Lives Under Your Desk Now
When you first set up a home workspace, the space under your desk was probably empty. Over time, a PC tower moved in. Then a power strip. An air purifier. Cardboard boxes. A half-used shopping bag. At some point, the space left for your legs shrank to just enough to tuck in two feet[^1].
Most people describe this state as "my desk is too small." But the real driver of fatigue isn't the size of the desk. It's whether your legs have somewhere to go when they want to change position.
What Legs Need Is Options, Not Stillness
An objective measurement study of office workers found that people sit for more than 5 hours a day at work, with a large share of that time accumulated in long, uninterrupted stretches[^2]. When one position is held too long, people unconsciously cross their legs, pull their feet under the chair, or leave one foot flat and the other lifted.
That isn't discomfort — it is a natural attempt by the body to keep circulation and muscle activity alive. Legs instinctively rest across several positions, not one. So what the space under your desk really needs, before "more room," is options.
The Real Dimensions of a Korean (and Global) Desk
According to Size Korea's Korean body dimension survey, the average height for Korean adults is about 173 cm for men and about 160 cm for women[^3]. Most domestic desks, however, are still 72–75 cm tall. At that desk height, a person of average build would need a chair as low as 43–47 cm just to place their feet flat on the floor.
In practice, the opposite happens. Chairs rise. The space below fills with cables and household objects. Legs spend eight hours a day not quite finding their place.
Clearance Guidelines — and a Realistic Alternative
BIFMA, the North American standards body for office furniture, includes knee and foot clearance as a basic design principle for computer workspaces[^4]. It generally recommends clearance of at least 510 mm wide and 380 mm deep beneath the work surface.
That ideal rarely holds up in a small home office. So the realistic alternative is to place a point of support inside whatever clearance exists. That is exactly the job of a footrest. Instead of asking the legs to decide where to go every few minutes, it says: this is your place[^5].
ROUMO's Answer — 512 mm Wide, 81 Combinations
ROUMO's Dual Rest LC99 is built at 512 mm wide — essentially matching BIFMA's recommended minimum of 510 mm. With 81 combinations (9 height settings × 9 front-back angles), it lets you sit in the same spot but shift your legs several times across the day. Heights and angles change with a knob — no tools — and the board slides easily when you nudge it with your feet, so even a small room can give legs a set of real options.
You can't always enlarge a room. But you can redefine what a small space does. One device that quietly tells the legs, your place is right here, is often enough to let them rest again.

Summary
- A cramped-feeling desk is usually not a size problem — it's that legs have no second place to go.
- Office workers sit more than 5 hours daily, and legs naturally want to change position.
- BIFMA recommends at least 510 mm of knee-and-foot clearance.
- LC99 provides a 512 mm-wide support with 81 position combinations — a place for legs inside whatever clearance you have.
