Purchase the optional, UV-resistant slip-on protective cover (shown on right side of image). This cover is not only great for holding your BackRest tightly in your favorite position, but also increases the life of your BackRest® holding up under intense sun and UV conditions. This sustains years of use in a car. Offered only in a durable but soft, black plush fabric. This actually adds to the overall comfort during use. MAINTENANCE: for maximum life, once per week open the valve and leave your BackRest fully inflated overnight.

For easy carrying open the valve and roll your cushion forcing all the air out and then close the valve. You will now have a small roll that will fit easily into a suitcase, briefcase or even a purse. When you're ready to use it, simply open the valve and it will self-inflate.
