The covers are thick twill or canvas type fabric

I bought the Sofa with the white cover 2 years ago, and additionally I bought one extra sofa cover, also in white. I added a little extra stuffing into the seat cushions to make them more plump, but other than that, I am amazed at how this sofa and the 2 covers have endured through the heavy use they have received, constant daily use, catnaps, several moves about the room, etc! The frame of this living room furniture is strong and sturdy. The price was so cheap, since I make use of their Coupon Codes. The covers are thick twill or canvas type fabric, very sturdy and wash well. I line dry them, and love the new, fresh outdoor scent when they come off the line! Sometimes I iron them, or use fresh off the line for that shabby, lived-in look. A great value for a very modest price for the budget-conscious!
