If you have kids, or are just naturally messy yourself, it is a good idea to avoid having too much open shelving.
Shelves have a tendency to rapidly overflow with toys, books, games or knick-knacks. They can also make it look like the kids have taken over your living room.
Avoid the over-cluttered look by utilising closed storage, which effectively reduces visual chaos. Alternatively, have a mix of open and closed storage so you and the kids can see some things, but it’s easy to clear away the messy bulk.
