The most preferred component for knock-down dining tables (tables with tops and bases sold separately) are wooden table tops, thanks to their versatility, durability, and ease in joining and fixing them onto a table base
Apart from versatility, there is another advantage of procuring wooden tabletops separately and that is the ease in transportation, readymade tables tend to be more voluminous and exporting or selling them separately for commercial or reselling use is hardly viable
Thankfully, manufacturers the world over abide by standard measurements for the spider (the bit that holds the wooden too to the base) which allows for easy fixing of the tabletop with the bottom,
At FurnitureRoots, we mainly sell these separately in wholesale orders to commercial dining businesses, mainly restaurants, cafes, bistros & food courts. We make these using hospitality grade materials and we also suggest table bases that go along with them
