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.
If your coffee table has a lower shelf you don’t have to fill both levels but if you choose to try lining up the items on each tier. Use two pairs instead of threes and don’t forget to play with heights. A lidded storage box or small basket can help keep the bottom level looking sharp while giving you a place to stash items like remote controls.
