Sometimes a coffee table that isn’t the standard height or width is exactly what a room needs. In this instance a very low coffee table creates a crisp horizontal plane in the foreground offsetting the long horizontal line of the credenza in the background. A higher table would have blocked the view of the credenza and competed with it; the varying heights add interest.
A lip edge or tray top on a coffee table is always a smart choice if you have a tendency to spill your coffee or have kids that will be using the coffee table for snacks and drinks. They’re also good if you entertain often and don’t want to worry about red wine getting spilled on your carpet.
