No matter what you are making or building, the base determines the strength and the lifespan of the product. If you have a weak foundation, your building will fail. You don't think about a building's foundation after you finish construction, unless the building fails. And often we don't think about it once it's finished; that is, until there is a problem. That's why it's "all about the base."
It all started with people making products that stood the test of time. Materials were once chosen because they would stand up to the wear that life puts on things. This is true about tables as well as everything else. Back in 1958, Frank Jacobs created the first 4-prong "standard" table base and made it out of cast iron. He believed in that product enough to stand behind it. He built the table bases with the intention that they would be around for a very long time.
So many things today are as cheaply made as possible. The idea is that when they fail, you will buy them again... and again. The manufacturers reflect their faith in the design by offering you the bare minimum warranty. One way that some table base manufacturers cut costs is by using stamped steel for their top plates and thinner gauged steel on their columns.
Not only do we build our table bases to last, we want the finish to last as well. No painted finish can out last powder coat. The metal surface gets a coating of dry thermoset polymer powder that we then bake on the metal. This forms an evenly applied, coating that will resist scuffs and look great for lots of years. This is the best protection for the table bases. Since we build them to last, they need a finish to last as long.
