Made from the same materials that we use for our ground pads. Self-inflating seat and back. We use the densified polyester fiber that is unaffected by temperature or water. The shell is our non-skid 300-denier polyester used for both sides of the chair. You will not slide off the chair, nor will it slide on the ground. Side release buckles allow you to lay it flat. It also has a web strap and side release buckle on one side so you can roll it and secure it like our ground pads. The chairs are available in two sizes.
