Black tables are notoriously tricky, especially if they are veneered, because the smallest scratch will show up. If you are the careful type, however, black is super cool and will always be so.
The only real consideration in buying this style of table is whether to go for an upmarket one, such as a French colonial table, or one with the rustic appeal of an English country farmhouse.
First, marble tables of any kind are bulky and heavy. Second, they have to be well looked after, as the marble can crack and stain. To avoid stains, keep the table cleared and clean at all times, covering it with a tablecloth or placemats when red wine and foods that can damage marble are on the menu.
To visualize how a bigger piece of furniture will look, take the time to block out the length and width on the floor, and also the height of the table. I usually stand on my tape corners with a tape measure, then try to fill in that space with furniture of a similar size, and take a step back to see how it’ll feel. It also helps to have a friend stand there with the tape measure while you have a look.
