Spare and replacement covers are available for all models. These covers are identical to the one your cushion arrived in when you purchased.
The medical grade cushions come with a medical grade cover. They are more substantial than the general use cushion covers and are required, by law, to have a flame retardant lining. Other sizes are available. If you don't see your size listed please order the model of cover that you need and send us an email on the "Contact Us" page and state the size you need.
