Certain tables can accommodate more leaves than others. Our Amish builders create guidelines for which tables can have more leaves added. They are the experts on their products and have high standards of stability. If a certain table is only available as a solid top in certain sizes, it is likely because adding leaves will compromise the stability. As long as you stay within the guidelines laid out by our Amish builders for each table, your stability will remain intact. Some styles may require additional support legs after a certain length.
