How to Put New Batting on a Couch

Drape quilt batting over the back of the sofa from the top of the seat cushions upward, over the top and down the back to the floor. Drape the second piece of batting over the seat cushions forward to the front of the sofa and down to the floor.

Sew the batting together along the joint where the seat back and seat cushions meet. Sew the batting to the batting, not to the leather or cover of the furniture. Use a curved upholstery needle and heavy-duty thread. It is OK to use large stitches, since your sewing will not be visible on the finished cover.

Drape batting over the side of one of the arms next. Cut and shape the batting to follow the side of the arm and where the arm and the back of the sofa meet. When the shape is correct, sew the arm batting together with the sides of the first and second pieces of batting. Sew as tightly to the sofa shape as possible so that the batting is snug against the existing fabric. Repeat with the second arm. As you sew the second arm, stretch the fabrics to increase the tightness of the fit.

Cut batting to fit the shape of the front of the arms. Sew the front batting to the arm batting that wraps over the sides of the arm, keeping the edges and corners smooth and the fit tight. A small section of the front arm batting may also be sewed to the seat base batting where it drapes from the front of the seat to the floor. Repeat for the second arm. Trim along the bottom of the sofa so that the batting is even.
