Some loveseat fabrics are treated with stain-resistant coatings to prevent stains from setting and adversely impacting the appearance of the loveseat. While these fabrics still require careful cleaning, they are less likely to retain stains, making them the best choice for loveseats in heavy use areas.
Loveseat covers are also an option if stains are a concern. Most loveseat covers are machine-washable and are available in a variety of styles to fit a loveseat without bunching or riding up. Some loveseats come with a slipcover, making it even easier to clean.
