Position the sectional slightly away from the wall if you wish to place its back against the wall. This will help prevent the top of the sectional from rubbing against the wall and becoming worn as people sit and stand.
Prevent pets from laying on the couch. Claws can tear leather or fabric, and pets can track dirt from outside to the sofa.
Keep food and beverages off the couch. Drinks are likely to spill and leave stains, while food can drop crumbs that either get ground into the fabric or sink into the seams of the couch.
Slide a protective cover or throw rug over the couch. You can find them in most color variations, and this allows you to wash the cover to remove stains and debris instead of having to wash the entire couch.
