One of the best ways to ensure your new slipcover looks good is to make sure you buy one that fits your sofa correctly. Follow our guide above to determine the exact size you need before buying. A well-fitting slipcover is a fantastic investment and will look great on your couch. Maintaining your slipcover is pretty straightforward. If you find your slipcover creasing or wrinkled, you can help remove them by dabbing your slipcover with a damp hand towel for 15 minutes. In the case of deeper wrinkles, you can mist the cover and manually press the fabric with your hands. You can also use a handheld steamer for hard to smooth creases.
