Ordered these for a rather high back dining chair with a support/brace that connects to the back posts and the seat on each side, so I wasn't sure they would work.  To my delight, the slipcovers fit the back of the chair nicely with a tailored look and fit over the brace, too.  The back section of the slipcover was tall enough for the high back.  The fabric is a heavy cotton duck, or similar to a lighter weight canvas, but softer.  The skirt hides the entire leg of the chair. I am very happy with these and the price was the best!
