Using these sofa covers is super easy. Just stretch the cover over your sofa, whether it's a 1 - seat, 2 - seat, 3 - seat, or 4 - seat one. Make sure to adjust it properly to fit the shape of your sofa. When it comes to maintenance, these covers are machine - washable. Just throw them in the washing machine on a gentle cycle with mild detergent. However, avoid using bleach as it might damage the fabric.

With these simple steps, your sofa covers will stay in great condition for a long time.
