A form that asks nothing of the room.
Looks sharp. Feels soft.
Ishi 石 begins with oak and a rule of subtraction — a form clarified, not decorated. We drew it by taking away: every edge softened until there was nothing left to force. Between stone and concrete, on a floor of river pebbles, it finds its first quiet.
A presence,
not a piece.
The Ishi 石 began as a question we kept asking in our architecture practice: why does a stool need legs? A stool is the simplest form of seating — a surface at sitting height. Its body is panel-built from combined solid oak boards, then shaped until the construction disappears into one quiet volume that meets the body.
The result is a shape that appears impossibly thin from across the room but feels substantial under your hand. It looks like it might tip. It won't.
At 430mm, the height is deliberate — low enough to pair with a sofa, tall enough to sit on comfortably. Flip it upside down and the seat becomes a surface for a book or a glass. One form, two functions.
The object.
Four hundred millimeters of North American oak, turned and tapered until one curve ran the full height. The grain you see is not applied — it is the tree's record, preserved. Run your hand from the top down. The edge that looked sharp is where your palm falls.
Six cushions. One oak base.
Kvadrat · Dedar · Leather
Materials that
earn trust.
Full-grain Italian leather, tested past 50,000 flex cycles — it only deepens with the years. Microfiber chosen for the way it holds light, not for the logo on it. Kvadrat wool rated to 45,000 rubs. Nothing here is here to impress you. It is here to last longer than the room.
We chose the materials first, then designed the cushion around them.
One base. Many moods.
Add a cushion. Change the fabric. Or leave it bare — the oak speaks for itself.
Natural Oak — deepens to honey over years. Charcoal — ultra-thin pigment layers, hand-sanded. Deep enough to read as charcoal, thin enough to feel the grain.
In the Space
One form, three rooms. In a sunlit corner where the day settles. At a window where tea turns cold. On a reading floor beside books and light. Ishi doesn't announce itself in any of them — it lets the room speak first.
What Goes Into This
19 days of wood preparation. Kiln-dried twice over nineteen days — because moisture is the enemy of a clean joint. Every joint tested with a flashlight. The curve is machined to the computed profile, then every edge hand-shaped to match. Water-based finish in multiple passes, each sanded between coats.
Direct by design. Built to outlast the room it's in.
This is the work an international jury saw when, of every stool entered to the SIT Furniture Design Award this year, they named one. The Ishi.
Dimensions
The ENWA Collection
Why Ishi exists
The ENWA curve, at the scale of one hand.
Ishi is the smallest expression of the collection: the same architectural edge logic, reduced to a stool you can move through a room. The silhouette stays precise from a distance; the edge softens under the hand.
Form
Table DNA at object scale.

The Ishi is panel-built from combined solid North American oak boards — not cut from one log. Its continuous exterior curve is digitally designed, machined to the computed profile, and resolved by hand so it reads as one calm form: stool, side table, or quiet sculptural object.
Solid wood. The Ishi Stool is made entirely from solid North American white oak (FAS grade, ~1,350 lbf Janka hardness) — never veneer, MDF, or engineered board. It is panel-built from combined solid boards, kiln-dried and sealed at 9–10% moisture for long-term stability.
The Ishi Stool is designed by Mililab, an architecture and design studio based in Tokyo, Japan, as part of its ENWA collection of eight solid-oak pieces. Mililab applies the same edge geometry it uses in architecture to furniture — precise from a distance, soft under the hand — and ships direct, DDP, to 34 countries.
