How to Make a Marshall Spring Cushion
Use a paper or a stiff paper pattern to fit the cushion to the chair size. As you make the pattern, add the normal 1/2" seam allowance all around. Add an additional 1/4" crown allowance to the sides and the front, but leave all the corners their actual size plus the seam allowance. (Don't add the 1/4" crown allowance to the corners.) Since each spring in the spring unit is approximately 3 inches in diameter, you probably won't be able to get an exact size unit to fit the chair. It is common to fill in padding around the edges of the springs to fill up the area that the springs don't fill. Many time cotton is used to till the area around the springs. In this particular spring unit we used foam scraps to fill in the area around the springs. Because this cushion was extra deep we use a thicker piece of foam on the front and the back. You'll need to add however much foam or padding is needed to fill up the distance around the springs. Starting with a Marshall spring unit that is the right size for your chair:
