Replacing a cane chair seat with a cushion is an easy fix if the cane is damaged or completely missing. This will allow you to make the chair functional and attractive since you can select any color and pattern of fabric for this type of seat cover. Making the chair cover is not difficult but it will require a few extra steps to make the cushion secure so that the chair is safe to sit on.
Remove any remaining cane using pliers and a flat screwdriver to loosen and pull any nails or staples holding the cane in place.
Place paper over the seat of the chair and draw an outline of the seat size and shape. Cut out the paper outline and fit the paper to the chair until it matches exactly.
Position the paper over 3/8 inch plywood. Trace the outline of the chair seat onto the plywood. Cut out the shape in the plywood using a jigsaw.
Place the plywood over the chair seat. Drill holes at each corner through the plywood and the chair base. Connect the plywood and chair base together with nuts and bolts. Tighten the nuts and bolts with a wrench and pliers.
Spray the top of the plywood with spray adhesive for foam. Press 2 inch foam into the adhesive. Trim the foam around the plywood using an electric carving knife.
Place a sheet of quilt batting on the work table. Position the chair upside down with the cushion centered over the quilt batting. Pull the top center piece of quilt batting to the underside of the plywood and staple as near to the edge of the chair as possible. Pull the bottom center to the back and staple followed by the left and right sides. Make sure the cushion is smooth. Continue stapling the batting to the chair bottom until you reach the legs. Cut and fold the batting around the legs and trim off the excess batting. Repeat for the remaining legs.
Position decor fabric face down on the work table. Center the upside down chair over the fabric so that the batting touches the fabric. Staple the fabric to the chair in the same manner used for the batting. Continue until the entire cover is attached. Trim off the excess fabric and the chair is ready to use.
