From my experience, it’s surprisingly difficult to find ready made sectional slipcovers. Until fairly recently, Sure Fit used to sell them, but they have decided to discontinue this range.
I’ve contacted several stores in my search for sectional covers, but no one seems to make slipcovers specifically for sectional furniture. However, SlipcoverShop.com have some useful advice. They suggest it is possible to use slipcovers on a sectional, providing you treat it as two or three entirely separate pieces of furniture. Of course, it depends on the style and seating arrangement of your particular seat, but many standard size sectionals can be covered by using both a sofa and a loveseat slipcover together. There will inevitably be a lot of extra fabric to hide, where the arms would be. But this can be dealt with by tucking it into the gaps where the seats meet.
Another option to consider is to get some custom slipcovers made to fit the exact dimensions of your furniture. For instance, you might need a combination of fitted sofa or loveseat covers and armless slipcovers. This is an affordable solution if you order them from SlipcoverShop.com. You will need to take careful and accurate measurements to ensure your new covers will fit correctly, but a real bonus is that your custom covers should be delivered within only 5 business days.
