Abstract
A method of packaging a self-inflating air mattress comprising an open cell foam core and an air impervious envelope. A plurality of mattresses are stacked intermittently between forming boards and evacuated. Each bag is then rolled up and placed in a flexible tubular container and the vacuum released on the mattress to provide a sung package. To remove the mattress, the container and mattress are compressed, the inflating valve closed, and the mattress slipped from the container.
