One of the first things you will have to ask yourself is where you will be placing your dining table. A round table curiously seems to draw all elements that surround it towards it, thereby anchoring itself (and the chairs) visually more than a rectangular table would. It also takes up less space.
For dining chairs that are built to last, there's no better material than oak. One of the strongest, prettiest and most accessible woods currently available, oak can be whittled by any master craftsman, into a fabulous set of dining chairs that will last a lifetime. Because oak is such a beautiful material, it can be turned to represent any design genre to an incredible standard. Contemporary, retro or traditional chairs will always look great in oak, not to mention bench seats.
