Design should not only be beautiful but durable, as well. While in some instances, a higher price tag may mean higher quality, this isn't always the case. Good design doesn't always have to be expensive.
In the case of pets and children, there is an inherent "wear and tear" factor to be considered. Even so, of course, we want to have all members of the family be able to feel joy and relaxation in a well-designed space.
This is where a thoughtful selection of pet- and child-friendly materials and finishes comes into play.
General rules of thumb
Some general design rules for pet- and child-friendly spaces include:
Washable fabrics.
Cushions with removable covers for easy washing or replacement.
Wipeable fabrics.
Sturdy construction.
