A baby high chair is a special seat for small children that allows them to sit upright and eat on their own. The hard plastic seat shape is suited to hold the frame of your baby, but it is not the most comfortable material. That's why high chairs come with a soft padded seat cover. If your cover is getting old and worn from use, you can easily make your own using the old one as a pattern. By making your own seat cover, you can design the cover using exactly the fabric you want.
Fold the fabric in half with the right sides facing away from each other and lay it out on a table. Fold the old seat cover in half and place it on top of the fabric along the folded edge.
Trace around the folded seat cover onto the fabric using a pencil. Follow the edges carefully so you copy the exact shape of the seat.
Add ¼ inch all around the traced shape on the fabric and cut the fabric out carefully using the sewing shears. Cut out the same shape from the quilt batting.
Lay the fabric on top of the batting with the right sides facing away from each other. Sew the pieces together at ¼ inch away from the edges with the sewing machine.
Copy the shape of the straps or pocket on the old seat cover onto the wrong side of another piece of fabric. The strap or pocket is the means of securing the seat cover onto the high chair.
Sew the fabric and batting together along the seams and folds of the old seat cover. The seams will allow the new cover to fold and shape to the high chair seat.
Cut out the straps or pocket from the fabric and sew them onto the batting side of the new seat cover. Remove the strap holes in the new seat cover according to the old cover holes.
Sew the bias tape around the entire edge of the new seat cover to cover the raw edges. Cover the raw edges of the strap holes in the same way.
Press the folds on the cover with the iron to help the new cover take its shape better. Fit the cover into the high chair and pass the straps through the holes.
Use a washable, durable fabric so you can throw the new cover into the washing machine if your child gets it dirty.
Don't use a lightweight fabric that will tear when used excessively or you will have to replace the cover after a short period of time.
