Mattress assemblies including static and adjustable mattress foundations generally include a foundation frame including side frame members and transverse frame members attached at respective ends by a corner bracket at each of the respective ends to define a generally rectangular shape. An adjustable support leg coupled to each one of the corner brackets for automatically elevating the foundation frame relative to ground. The adjustable support leg can include an outer tubular member fastened to an interior facing portion of the corner bracket including an end cap, wherein the end cap includes an aperture. A motorized linear actuator can be coupled to the outer tubular member, which can include a motor and an extendible portion coupled to the motor. The extendible portion is configured to selectively retract from and extend through the end cap to change the elevation of the foundation frame relative to ground.

An inflatable device includes an inflatable bladder configured to inflate when the entirety of the inflatable bladder is located under a mattress, an air compressor configured to inflate the inflatable bladder when the inflatable bladder is located under the mattress, at least one tube fluidically connecting the air compressor to the inflatable bladder, and a least one user interface in operable communication with the air compressor. The at least one user interface is configured to initiate the air compressor and inflate the inflatable bladder.

An adjustable bed frame includes first and second bed frame units. The first bed frame unit includes a first longitudinal rod, a second longitudinal rod, a first transverse rod, and a first vertical rod. The first longitudinal rod, the second longitudinal rod, and the first transverse rod are all pivotally attached to the first vertical rod. A locating hole passes through a side of the first transverse rod. The second bed frame unit includes a third longitudinal rod, a fourth longitudinal rod, a second transverse rod, and a second vertical rod. The third longitudinal rod, the fourth longitudinal rod, and the fourth transverse rod are all pivotally attached to the second vertical rod. A locating pin is disposed on a side of the second transverse rod. In an assembled state, the second transverse rod fits inside the first transverse rod, and the locating pin protrudes out through the locating hole.

Modular mattress systems include mattress modules configured such that a plurality of mattress modules are configured to form a first modular mattress of a first selected geometry and are reconfigurable to form a second modular mattress of a second selected geometry.

An apparatus includes a plurality of base plates structured to be positioned on a surface, and a bed frame comprising a plurality of rails configured to receive a bed thereon. A lifting assembly is coupled to each of the base plates and the bed frame. The lifting assembly includes a plurality of lifting members pivotally coupled to base plates and the plurality of rails of the bed frame. A securing mechanism selectively secures at least a portion of the lifting members in a fixed position. The lifting assembly is movable between a first configuration in which the plurality of rails of the bed frame, and thereby the bed positioned thereon, is positioned proximate to the surface, and a second configuration in which the plurality of rails of the bed frame and, thereby the bed are raised off the surface.

An electric bed with an adjustable bed length, containing an upper head bed frame, an upper foot bed frame, a lower bed frame, and a plurality of bedboards. Wherein at least one of the plurality of bedboards is pivotable relative to the lower bed frame. Wherein either of the upper head bed frame and the upper foot bed frame is fixed/immobile relative to the lower bed frame while the other contains a moving component which moves back and forth relative to the lower bed frame between a rest position and an extension position. Wherein the at least pivotable bedboard keeps horizontal and the upper head bed frame is away from the upper foot bed frame by Distance 1 when the moving component is located at the rest position, while the at least one pivotable bedboard pivots and there is Distance 2 between the upper head bed frame and the upper foot bed frame when the moving part is located at the extension position. Wherein Distance 2 is longer than Distance 1. The bed length is adjusted in the above-mentioned way to overcome the defect in the traditional electric bed where the bed length is shortened after the posture is changed, causing part of the matress to have no support basis. Further, the electric bed works reliably with an always pleasing appearance and can be conveniently assembled with a low risk of injury to a user's hand.

The disclosure generally relates to an adjustable foundation or bed, in particular having a dual-tilt adjustable foundation. Upper and lower segments of the adjustable foundation subframe are rotatable relative to each other, thus allowing the upper portion of the subframe to tilt and assume an inclined, flat/horizontal, or declined position relative to the lower portion of the subframe. An articulating mattress support surface above the subframe can move independently from the tilting subframe.
