Simple Modern Bar Stool

Attach the short seat aprons to the seat with 2-1/2" screws and glue.

Attach the longer aprons to both the seat and the shorter aprons with screws and glue, boxing the underside of the seat.

Build two matching leg assemblies from the front legs, back legs, diagonal braces, and leg supports, using 2-1/2" screws and glue at every joint. Keep the assemblies as close to identical as you can — any mismatch will make the stool rock.

Assemble the seat and both leg assemblies, screwing up from underneath the seat so no screw holes show on top. Sand every edge and finish as desired.
