Reupholstering is fixing up old or worn-out furniture by replacing or adding fabric. For example, you could reupholster an old sofa with new material, replace the cushion on a dining chair, or update the fabric on a headboard. For these kinds of jobs, especially when working with thick or stacked materials, a heavy-duty sewing machine is essential because it can handle thick fabrics while keeping the quality of the stitches the same. Without a heavy-duty machine, problems like broken needles, uneven or puckered stitches, and long-term stress on regular sewing machines could damage the motor.
