Abstract: A multi-layer air mattress having an upper section with one or more layers of comfort material and a lower section having one or more layers of support material. A middle layer is arranged between the upper and lower sections and includes apertures for retaining air springs. The air spring has two cups that are sealed to a form plate to create a welded joint that encapsulates a sealed internal cavity. An invertible nipple is pressed into the internal cavity to reduce the cavity volume and self inflate the air spring.

Abstract: The invention provides a mattress comprising an array of air springs, each in communication with a supply of air for selectively varying the air pressure within said spring, so as to provide a resilient body against which a user may recline; an aperture in an upper surface of each air spring, providing access to a cavity within said spring, said cavity open to ambient pressure and sealed from the air supply.

Abstract: The invention provides a mattress 5 comprising an array of air springs 30, each in communication with a supply of air 65 for selectively varying the air pressure within said spring, so as to provide a resilient body 30 against which a user may recline; an aperture in an upper surface of each air spring, providing access to a cavity 50 within said spring, said cavity open to ambient pressure and sealed from the air supply 65.

Abstract: A landscaping vegetation border unit that is elongated and is formed by a pair of spaced apart sidewalls and a bottom wall which has an open top. The unit defines an internal compartment. Each of the sidewalls are divided by a series of transverse slots that form each of the sidewalls into a plurality of separate panels. The bottom wall includes an adjustment means that will permit the sidewalls to be bent. The soil and growable vegetation is to be placed within the internal compartment with the border units to then be used to separate to divide separate cement sections in a landscape environment.

Abstract: A human body support structure which provides a crossed series of cords mounted within an enclosed space formed by a rigid frame. Mounted on each of the cords are pins with a longitudinal axis of the pins being oriented perpendicular to the cords. Located between directly adjacent pins is a spacer with each spacer being mounted on a cord. The cords are slightly stretchable assuming a taut relationship when mounted relative to the frame. A human body is to be placed against and supported on the upper surface of the pins.
