Simple Wood Stool

Stand the four legs up in their final position and mark the inside corner of each one before cutting anything else. Because the leg-end angle is only 5° and is a double bevel, it's genuinely easy to lose track of which corner is which — always remember the marked corners face the inside of the leg.

Build two identical leg frames, joining the short rungs and one pair of top supports to each pair of legs, referencing the marks from the first step.

Add the additional rungs to each leg frame. Don't forget the glue on these — they're bracing rather than primary structure, and the glue is what keeps a stool this size from developing a wobble under real weight.

Attach the remaining top supports to join the two leg frames into the complete stool base.

Attach the seat by screwing up through the top supports into its underside — this hides every screw hole from the surface people actually see and sit on.

Fill any exposed holes, sand thoroughly, and finish.
