When ordering new upholstery, you have the option of choosing a cushion or a cover.
A cover is only the pre-sewn fabric. It does not include new foam or new wood. When you receive a new cover, you must cut off the old one and staple the new one to your old piece of wood.
A cushion is fabric, foam, and wood all put together for you. When you receive a new cushion, you must un-bolt the old one from your table frame and reuse the bolts to put on the new one.
Note: there is no option to purchase headpiece covers as they are difficult to replace without compromising the integrity of the fabric.
