Vacuum upholstered furniture once every one or two weeks to remove abrasive dirt and grit that can build up and damage the fabric.
Rotate and flip furniture cushions every so often to spread out the wear on them and prolong the life of your furniture.
Put on a rubber mitt and run your hand over your upholstered furniture to remove pet hair or make it easier to pick up with a vacuum cleaner.
Keep your blinds or curtains closed during the day while you are not at home. This will reduce your furniture's exposure to sunlight, which can cause the fabric to fade.
Have your upholstered furniture professionally cleaned every one to two years.
