Cotton bump under clothsWe make them in sizes to fit all our standard sizes of Instant tables and can make custom sizes too. We make the under cloth slightly shorter than floor length as the bump will stretch. To work out what size under cloth is needed to fit your table; add the diameter of your table to twice the height of the table and that gives you the diameter of your cloth. Use the 'own input' section below to specify the size of cloth you would like.
