If the legs are uneven, or the last leg will not come together quite as nicely as the first leg, the difficulty is usually the result of each screw being completely tightened before moving on to the next step during assembly.
The instructions call out an initially loose connection for both chair leg supports and stool:
- Loosen the bolts for attaching the braces without removing them and ensure that all legs are touching the floor.
- Work on each leg in turns, tightening the bolts little by little and watching that no gapping around the braces prevents an even connection.
- Watch the spacing of the braces around the legs.
