Abstract
A mattress assembly, comprising: substantially nonporous bottom and side walls forming a mattress foundation; a mattress inner core disposed in the mattress foundation being permeable to air; nonporous top cover covering the mattress inner core, the nonporous top cover having apertures at predetermined locations to allow the flow of air therethrough; and a fan disposed with the mattress assembly for forcing air into the mattress inner core whereby the air is forced out the top cover so as to reduce the accumulation of carbon dioxide in bedding on the top cover of the mattress.
Claims33
A mattress assembly, comprising:
- substantially nonporous bottom and side walls forming a mattress foundation;
- a mattress inner core, having a frame structure including resilient support elements integral therewith, disposed in the mattress foundation as an integrally removable and insertable unit and being permeable to air;
- a top cover of nonporous material covering the mattress inner core, the nonporous top cover having apertures at predetermined locations spaced apart by less than 2 cm to allow the flow of air therethrough,
- releasable attachment mechanisms disposed to attach the top cover about its periphery to the side walls of the mattress foundation, and to permit repeated removal and reattachment of the top cover;
- and
- a fan disposed with the mattress assembly for forcing air into the mattress inner core;
- whereby the frame structure is readily removable as a unit for cleaning and the air is forced out the top cover so as to reduce the accumulation of carbon dioxide in bedding on the top cover.
4 more elements
A mattress assembly, comprising:
- substantially nonporous bottom and side walls forming a mattress foundation;
- a mattress inner core, having a frame structure including resilient support elements integral therewith, disposed in the mattress foundation as an integrally removable and insertable unit and defining an open area for the flow of air;
- a top cover of nonporous material covering the mattress inner core, the top cover having apertures at predetermined locations to allow the flow of air therethrough, said top cover being removable to allow cleaning of the top and bottom surfaces;
- attachment means for attaching the top cover about its periphery to the side walls of the mattress foundation, the attachment means being reusable so as to permit repeated removal and reattachment of the top cover;
- means for attaching bedding to the mattress foundation for maintaining the bedding in a taut condition, said means including a plurality of retaining mechanisms provided on the side walls of the mattress foundation;
- bedding attachable to the mattress assembly by attaching mechanisms operating co-operatively with respective retaining mechanisms of the mattress foundation;
- and
- a fan disposed with the mattress assembly for forcing air into the mattress inner core whereby the air is forced out through the top cover.

A crib assembly comprising:
- a mattress including
- substantially nonporous bottom and side walls forming a mattress foundation;
- a mattress inner core, having a frame structure including resilient support elements integral therewith, disposed in the mattress foundation as an integrally removable and insertable unit and defining an open area for the flow of air;
- a top cover of nonporous material covering the mattress inner core, the top cover having apertures at predetermined locations spaced apart by less than 2 cm to allow the flow of air therethrough, the top cover being removably attachable about its periphery to the mattress foundation to allow cleaning of the top and bottom surfaces;
- releasable attachment mechanisms disposed to attach the top cover about its periphery to the side walls of the mattress foundation, and to permit repeated removal and reattachment of the top cover;
- and
- a fan disposed with the mattress assembly for forcing air into the mattress inner core whereby the air is forced out through the top cover;
- and
- a crib supporting the mattress.
6 more elements
A method of reducing the accumulation of carbon dioxide in bedding, comprising:
- forming a mattress having substantially nonporous bottom and side walls and a removable top cover which is nonporous except for apertures at predetermined locations to allow the flow of air therethrough;
- disposing an integrated mattress inner core within the mattress, the inner core including a frame structure and resilient support elements integral therewith, and being integrally removable and insertable;
- releasably attaching the top cover to the side walls of the mattress so as to maintain the top cover in position over the mattress and to permit repeated removal and replacement of the inner core;
- and
- forcing air into an interior area of the mattress at a sufficient rate to percolate air through the top cover of the mattress.
