What is the exact seat height I need for a standard 30" conference table?

For a standard 30" conference table, the ideal chair seat height is 17"–19" for most adults — this puts the seated thigh roughly parallel to the floor with feet flat and provides adequate knee clearance (4"–6") under the table apron. Chairs with a pneumatic adjustment range of 16"–21" accommodate the full range of adult seated users. If your table has an apron (the side panel below the table surface), measure from the floor to the bottom of the apron — you need at least 24" of knee clearance.
