Filippa extension leaf 45 cm in whitewashed oil-treated oak. Fits the Filippa round dining table in the same finish. When purchasing the dining table, one extension leaf is included, and this additional leaf allows for further extending the table. In total, it is possible to use two extension leaves in the dining table, creating a dining table of 210 cm. Remember to store the extension leaves flat in the same room temperature as the table.
Also, remember that oil-treated surfaces should be treated with furniture oil before use and then regularly 2-3 times per year. This is especially true for parts of the table's top surface, to maintain resistance to stains and scratches. Before oiling the furniture, the surface needs to be cleaned to remove dirt and grease, a wood cleaner intended for the purpose should be used.
