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.
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.
Trestle tables can give you flexibility along the sides of the table, but can limit space at the ends of it. Look closely at how much space there is between the edge of the table and where the trestle supports are attached to make sure there’s room for your knees.
If you fall in love with a metal or marble table, don’t be discouraged from buying it, but do think about how you might safely transport it. As suggested above, choose a small, round marble table, or go for a wooden table with detachable legs.
