If you are looking for a table to suit an urban-industrial decor theme, don’t go all-out with a (heavy) metal table but consider a (lighter) wood table with some metal design features.
Consider a designer pack-and-go dining table. Plywood is lightweight and durable, and a plywood table can be flat-packed and assembled as needed at home. Your dining table then can be packed up and moved as necessary. Plus it works well in a home with modern Nordic or contemporary Asian style.
Marble is a big investment, but without exception marble dining tables are nearly always showstoppers. Tables crafted from quality imported marble are extremely beautiful.
They also have an uncomplicated design suitable for most schemes, although, pleasingly, many country tables feature elegantly turned legs that support the tabletop.
