There is so much to love about a black small dining table. It will make its presence felt with its dark, brooding shape, rather than its physical size, and it will stand out well against a backdrop of a different colour. Black might only be the colour of part of the table, and the wood or metal frame in particular, with glass or concrete used for the top. The options here are many.
On a practical level, a black small dining table could be an extendable option, taken up to its maximum size when required, or it could be a drop-leaf or folding style. Assess the amount of space you have, and decide if you really only need to bring the table out on certain occasions.
A black small dining table might make its home in a small dining room, or to the side of a kitchen or lounge. There will definitely be black dining room furniture available, and you could balance two halves of a lounge/dining space with a black sofa on one side. Try a black side table too.
