First concept sketch. The idea was a single chair that could serve two different functions depending on its orientation.

Development process. I flipped it around in different ways, refining the design little by little. After four iterations, the final design was set.

Laser-cut jig. More accurate and durable than paper printouts. Should’ve skipped the unnecessary engraving though—cost too much.

Pro tip: cutting two sheets of 3T MDF is cheaper and faster than cutting one sheet of 6T. Saves both material cost and cutting time.

Completed jig.
I kept looking at it, thinking, “Oh… so this is the vibe.”

One advantage of laser-cut jigs is being able to mark domino joint positions directly on them.

Drawings and wood layout plan.

Chose walnut for the build—a premium hardwood.
Costs about three times more than cherry. A plank sized 30×160×2480 mm goes for around 90,000 KRW.

Because there are many parts and large pieces, precise planning was needed to minimize waste.

Cutting roughly with extra margin left.

Gluing pieces together. Thought the wood was warped when it wouldn’t go through the planer properly, but it turned out the front roller was set too high. Need to check that next time.

The most efficient layout I managed.
“Most efficient” only because there might’ve been an even better one.

Before using the jigsaw, I made entry slots for the blade.

Lots of holes.
Tip for hole saws: lift and press repeatedly to prevent burning from sawdust buildup. Also, secure the wood tightly so it doesn’t spin with the drill.

Band saw for more detailed cuts.

Using a trimmer with the jig to match the shape.

Another “oh… this is it” moment.

Assembly always needs to be quick and precise.

“Stick well—yap!”

Planed the edges to round them off.

Final sanding for a smooth finish.

Applied oil generously.

And finally… wow.
