A foldable bed assembly includes first and second frame units and two hinge units. The first frame unit includes two first longitudinal frames, and a first transverse frame. The second frame unit includes two second longitudinal frames and a second transverse frame. The second frame unit is pivotable relative to the first frame unit and convertible between a normal state, where the first transverse frame is spaced apart from the second transverse frame, and a folded state, where the second longitudinal frames are respectively overlaid on the first longitudinal frames and the first transverse frame is overlaid on the second transverse frame.

A removable mattress topper for a mattress assembly is provided that includes a foam layer including one or more vibrating units. The removable mattress topper includes a cover encapsulating the foam layer. The cover includes a top panel, a bottom panel, and sidewalls extending between the top and bottom panels, wherein the bottom panel comprises a zippered portion extending about at least a portion of a peripheral edge of the bottom panel. Also disclosed are mattress assemblies including the removable mattress topper, wherein the mattress assembly includes a mattress core and a cover encapsulating the mattress core, wherein the cover includes a top panel and a zippered portion about a peripheral edge of the top panel. The zippered portion of the mattress core is configured to mechanically engage the zippered portion of the removable mattress topper.

A modular bed includes a frame assembly, a plurality of elongated support units, and at least one vibration assembly including a rack, a stretchable web, and a vibration motor. The rack is detachably mounted on two selected adjacent ones of the elongated support units. The stretchable web has a central portion suspended across a lower opening of the rack. After the through bore is stretched to permit insertion of a positioning plate of the vibration motor, resilient retraction of the through bore causes a neck portion of the vibration motor to be trapped in the through bore with a motor body and the positioning plate of the vibration motor to be in abutting engagement with upper and lower surfaces of the stretchable web, respectively.

Provided is a three-dimensional wave generating device and a multifunctional motion bed having the same. A safety device prevents a driven pulley and/or a driven pulley to which an eccentric shaft is coupled from being separated from a coupling shaft. Therefore, operation stability is secured while noise caused by separation or unstable coupling of the driven pulley and/or eccentric shaft in a three-dimensional wave generating device is prevented from occurring, and when a functional motion bed to which the three-dimensional wave generating device is applied is provided, the user can feel a three-dimensional wave more effectively in bed.

A motion imparting leg for imparting an oscillating or reciprocating rectilinear motion to a rocking bed, comprising a base, an upper surface movable relative to the base for imparting the oscillating or reciprocating motion to the rocking bed, a servo motor for driving movement of the upper surface, a position sensor for determining the rotational position of the servo motor or the position of the upper surface, and a motor controller for controlling the servo motor based on data from the position sensing means.

A sway bed has a fixed base and a swaying frame defining a bed surface movably attached thereto by a plurality of sway linkages. An oscillating drive operably interfaces the fixed base and the swaying frame. The oscillating drive comprises a geared motor turning a distal end of a crank slidably retained within a channel substantially orthogonal with respect to the bed surface.

An adjustable bed includes a frame structure; an upper support bracket and a lower support bracket pivotally connected to the frame structure; a plurality of platforms disposed on the frame structure and supported by the upper support bracket and the lower support bracket without using hinging means; and an adjustable assembly coupled with the frame structure and the upper support bracket and the lower support bracket for operably adjusting one or more of the plurality of platforms in desired positions.

An adjustable bed includes a frame structure having a first frame, a second frame, and a pair of connection bars detachably connecting the first frame and the second frame to one another; a plurality of platforms disposed on the frame structure; and an adjustable assembly coupled with the frame structure for operably adjusting one or more of the plurality of platforms in desired positions.

A dynamic furniture system includes a first frame portion; a set of rollers mounted to the first frame portion; a second frame portion including one or more rockers having a roller-interface surface having a curved profile; wherein the set of rollers interface with the roller-interface surface of the rockers such that the second frame portion is moveable relative to the first frame portion; a set of one or more electromagnets mounted to or integrated with the first frame portion or the second frame portion; a set of one or more magnetically-interactive elements mounted to or integrated with a different one of the first frame portion or the second frame portion; and an electronic control system configured to vary a parameter of electrical energy supplied to the set of electromagnets over time to induce back and forth motion of one of the first frame portion or the second frame portion.

A bed frame system and a movable frame may simulate movement of a body of water. The bed frame system and the movable frame may improve sleep and sleep patterns of a user and may provide additional health benefits. An intensity of movement of the bed frame system and the movable frame may be controlled by utilizing a controller and/or a mobile application. A predetermined time period of movement may also be controlled by utilizing a controller and/or a mobile application.
