Abstract: A waterproof carrying bag having a flexible, liquid impervious body portion with an internal storage cavity and a substantially rigid neck portion having an inner surface defining an opening into the container. A closure seats on the neck portion, covering the opening. The closure has a sealing gasket which is compressed between the closure and the neck portion when the closure is seated on the neck, substantially preventing the passage of moisture between the closure and neck portion.

Abstract: Camping mattress having a head section and a foot section adapted to be rolled up for carrying, and being tapered in plan view such that at least one of the sections decreases in lateral dimension toward its outer end and the mattress is wider toward the center and narrower toward the end. The mattress has two sheets of flexible air-impervious material sealed together to form a plurality of chambers, a body of resilient material in one of the chambers, and a valve controlling air flow into and out of the chamber with the resilient material to regulate expansion and compression of the material.

Abstract: A mattress construction includes a water mattress and a resilient peripheral cushion extending about the water mattress. A flexible cover is positioned on the resilient cushion, with the resilient cushion including a peripheral inner rail and a peripheral outer rail, the interior surface of the inner rail providing peripheral support for the water mattress. The inner and outer rails are interengaged whereby the inner rail resists upward movement of the outer rail.

Abstract: A mattress construction includes a water mattress and a rigid, peripheral and bottom support for the water mattress. There is a resilient cushion extending about and over the water mattress and the rigid support. A flexible cover is positioned about the resilient cushion. There are lift-off, lock-down means in the form of facing peripheral hook and loop fastener strips which integrate the cushion, cover, water mattress and support into a unitary structure.
