FLUX STOOL

Flux Stool — Solid Walnut Stool
No back. No padding. No compromise on the wood.

The Flux Stool is the seat for people who prefer the material over the upholstery. A backless solid walnut stool with a hand-carved saddle seat, turned cylindrical legs, and a full stretcher system that doubles as a footrest — it is a piece rooted in Japanese craft tradition and built from 100% FAS-grade North American black walnut with nothing added and nothing hidden.

It works at the Flux dining table, beside the Senu Desk, at a kitchen island, or anywhere a seat needs to be moved, repositioned, and used without ceremony. At 44.5cm seat height and pre-assembled out of the box, it is also the most immediately usable piece in the collection.

The Seat: Carved Saddle Form

The defining feature of the Flux Stool is its seat — a single piece of solid walnut carved into a concave saddle profile that is wider at the front than the back, with the front corners upturning slightly outward in a wing-like flare. This is not a flat board with rounded edges. It is a three-dimensionally sculpted surface that follows the natural seated posture: wider where the thighs rest, narrower where the body centres, with a gentle scoop that keeps the sitter positioned without the need for a back support.

The carving is done entirely in solid walnut — no bentwood lamination, no moulded composite. The grain of the wood runs the length of the seat, and the natural figure of the walnut becomes most visible in the curved sections where the light catches the changing grain direction.

All edges across the seat — the top surface, the underside perimeter, and the distinctive upturned front corners — are fully rounded and hand-sanded smooth. There are no sharp transitions anywhere the hand or leg might contact the piece.

The Joint: Seat to Leg

Where the seat meets the leg frame, the Flux Stool uses a curved bracket — a yoke-form connection piece that flows organically from the top of the leg into the underside of the seat, distributing the load of the seated weight across a broader contact area rather than concentrating it at a single point. The joint is pinned with an exposed dowel, visible as a small detail on the outer face of the bracket — the same craft signature found across the Senu collection's exposed elm pins.

This connection method is structurally superior to a simple mortise-and-tenon at this angle because it manages the lateral force that occurs when a sitter shifts weight sideways — the most common cause of stool joint failure over time.

The Base: Turned Legs, Full Stretcher System

The four legs are solid walnut turned to a cylindrical profile — rounded rather than squared or tapered. The cylindrical form is a deliberate craft choice: it requires more precise lathe work than a square leg, produces a softer visual weight, and is more comfortable against the leg when the stool is tucked under a table.

The legs are connected by a full stretcher system — side stretchers on both flanks and a front stretcher completing the base frame. The front stretcher is positioned at a height that functions naturally as a footrest when seated, keeping the feet elevated off the floor and reducing fatigue in extended sitting. It is the detail called out specifically in the original product documentation, and it is the difference between a stool that is comfortable for ten minutes and one that is comfortable for a meal.

100% Solid Walnut — No Exceptions

Unlike many of the other pieces in the collection that use secondary hardwoods for internal structure, the Flux Stool is built entirely from FAS-grade North American black walnut. Every component — seat, legs, stretchers, bracket joints — is the same material. The grain is consistent across the whole piece, the colour reads as unified, and there are no material transitions that require concealment.

It is the simplest brief in the collection and the one that leaves nowhere to hide. The wood is the product.

Pre-Assembled — Ready to Use

The Flux Stool ships fully assembled. There is no flat-pack, no Allen key, and no assembly instruction sheet. Take it out of the packaging and use it. For a piece this compact and this structurally unified, factory assembly is also structurally superior — the joints are set under controlled conditions with consistent clamping pressure, rather than assembled by hand in a home environment.

Specifications

Measurements may vary ±1cm due to the natural properties of solid wood.

Pair With

The Flux Stool is designed to sit alongside the Flux Dining Table — the walnut grain, Dabao lacquer finish, and mid-century craft proportions are consistent across both pieces. It also works at the Senu Desk as a backless desk stool, or used independently as a bedroom or entryway seat. Sold individually; works in pairs or sets of four beneath the Flux dining table.
