Get the Correct Size of Furniture
Furniture placement is often very difficult. I always put a room into a scale drawing to see the relationship of pieces and what sizes look and feel the best. But what is most challenging is to make sure the sofa size is not too large or too small. I find that sometimes the pieces of furniture can measure the same, but look very different in the space.
A coffee table should be no more than 15 inches from the sofa so that it can to used to place drinks or put your feet up. Side tables should be the same height as the sofa arm or slightly lower.
There can be really neat accent pieces or perhaps a great leather ottoman. Side tables are much more interesting if they do not match. Look for fun unique pieces that make a space interesting and make it uniquely yours.
