It depends on the purpose you intend for your furniture cover. Among common furniture, fabric material includes vinyl, polyester, and fleece. Among the three, vinyl is the cheapest. Its durability depends on the fabric’s thickness. Polyester, on the other hand, is stronger and can be attractive when colored correctly. Unlike vinyl, polyester is more reliable in terms of water protection. Fleece, a common material used for inner linings of furniture covers and other fabric, gives a plush, softer feel on the furniture cover. It also helps lessen the risk of fabric deterioration or damaging the furniture due to exposure to outside elements.
