Claims17
In a mattress construction:
- a water mattress comprising a flexible bladder for holding a body of water, a rigid circumscribing framework defining a cavity for the mattress and providing lateral support of the body of water in the mattress, and an outer shell overlying the framework and cavity, said outer shell comprising a cushion of resilient padding extending along the top and outer sides of the framework and a flexible cover secured to the cushion and overlying the cavity and the top and outer sides of the cushion.
In a mattress construction:
- a water mattress, a rigid circumscribing framework exteriorly engaging the water mattress to provide lateral support for the water therein, said framework including a water impervious, flexible liner extending along the sides of the framework and beneath the water mattress, an insulative pad overlying the water mattress, a cushion of resilient padding extending along the top and outer sides of the framework, the upper surface of the cushion being generally level with the upper surface of the insulative pad, and a flexible cover comprising a top panel having two superposed sheets of fabric and an intermediate layer of insulative padding extending over the upper surfaces of the insulative pad and cushion, a side panel extending along the outer side of the cushion, and a bottom panel secured to the under side of the cushion, the side panel being joined to the top and bottom panels by binding tape and stitching along the upper and lower side edges of the cushion.
In a mattress construction:
- a water mattress, a rigid circumscribing framework providing lateral support for the water mattress, a cushion extending along the upper and outer sides of the framework, said cushion being of sufficient thickness above the framework to make the framework substantially imperceptible to a person sitting or lying on the lateral margins of the mattress, and a flexible cover overlying the cushion and the water mattress.
In a mattress construction:
- a water mattress comprising a flexible bladder for holding a body of water, a rigid circumscribing framework defining a cavity for the mattress and providing lateral support for the body of water in the mattress, a cushion of resilient padding extending along the top and outer sides of the framework, and a flexible cover comprising a top panel which overlies the mattress cavity and cushion, a side panel which extends along the outer side of the cushion and a bottom panel which extends along the underside of the cushion, the side panel being joined to the top and bottom panels by binding tape and stitching along the upper and lower side edges of the cushion.
