Here are some home care hints you hopefully might find handy. Periodically changing the parts that get walked on the most helps even out the wear.
Cushions take the most punishment.
Regularly flip them over so that the fabric on each side wears evenly. Once a week, vacuum the sections of the furniture that receive the most contact - seats, back, and arm rests. When crushing does occur, moisten the area with warm water and let it sit. Then brush the carpet pile back and forth to help it stand up straight. Blot up remaining moisture.
