Adjustable bed frame rail riser assemblies include a first riser assembly that detachably couples to a first rail of a bed frame and a second riser assembly that detachably couples to a second rail of the bed frame. Each riser assembly includes a wedge with a top surface with a slope that inclines or declines a mattress or box spring that resides on the top surface. The riser assemblies may be detachably coupled to standard metal or wooden bed frames and need not be permanent fixtures of the bed frames. The riser assemblies of the present invention do not require levers, arms, or electrical parts. The riser assemblies can further be coupled to standard metal or wooden bed frames, without requiring specially designed beds or bed frames.

Disclosed are adjustable supports, bedding support assemblies, and foldable bed frames having adjustable supports, bedding support assemblies or both. A foldable bed frame includes first and second sub-frames, first and second leg assemblies, and a plurality of adjustable supports. First and second sub-frames are pivotally connected with each other at their proximal sides. First and second leg assemblies are pivotally connected with the first and second sub-frames, respectively. Each adjustable support has one end connected to a sub-frame, and the other end connected to a leg assembly. An adjustable support includes movably coupled inner and outer bars, and a locking and unlocking mechanism to selectively restrict the inner and outer tubular bars from moving with respect to each other and thus selectively restrict the leg assembly from rotating with respect to the sub-frame.

The present invention relates to a multi-function mattress composed of MagLev suspension, stretched net surface and adjustable underneath elastic cushion modules for optimized body contour-fitting and head-shoulder-neck massage by the motorized roller. This mattress design provides a unique solution to achieve the best body contour-fitting with a simple structure. The MagLev suspension technology helps generate the best support for the entire body during the sleep. It also provides comfort and relaxation that is associated with the sleep-cool technique, which is achieved through the underneath hollow structure. This mattress can be made at efficient cost to perform multi-function. The energy-efficient design also reduces its impact on the environment.

The invention provides a bedding structure used for supporting back and neck, which is composed of an adjustment base, a plurality of extension arms and a plurality of support plates. It may only use a rotating motor to drive the mechanical deformation of a lying structure to form an ergonomically sitting structure or a structure between lying and sitting.

A shelter and associated methodology for operating a shelter that is selectively positionable between an operable raised mode and an idle lowered mode. The shelter has an outer frame with a first upstanding perimeter wall defining an open top. An inner frame has a second upstanding perimeter wall nested within the first upstanding perimeter wall in the lowered mode. Means are provided for raising the inner frame through the outer frame's open top and above the outer frame in the raised mode. The shelter can further include a second inner frame having a third upstanding perimeter wall nested within the second upstanding perimeter wall in the lowered mode. In that case, the means for raising is further configured for raising the second inner frame through the inner frame's open top and above the inner and outer frames in the raised mode.

An adjustable bed base has a subframe assembly including a subframe which may be inclined relative to a stationary frame by a primary linear actuator. An articulating deck is attached to the subframe. Secondary linear actuators articulate the deck. The subframe assembly is pivotally secured to a portion of the stationary frame. The subframe may be inclined by extending the primary linear actuator which moves ramps, causing wheels attached to the subframe to ride upwardly along the ramps, thereby raising the head end of the subframe relative to the stationary frame.

An adjustable bed base has a stationary frame. An articulated deck is attached to the frame. The deck may be flat or fully articulated depending upon the position of linear actuators which are secured to the frame at one end and to a brace at the other end. The deck may be further inclined due to slotted mounting brackets, thereby allowing access to components below the deck members.

A mattress raising inflatable including: a. an inflatable body formed of panels having: i. a boxlike structure when inflated with a periphery that substantially follows a rectangular outline matching or just smaller than the mattress to be lifted; ii. a plurality of inflating sections of the boxlike structure of the inflatable body located to raise a number of spaced peripheral areas and central areas; b. an inflating valve in the periphery and substantially external to the inflatable body allowing for pumping to inflate the inflatable body while not providing an impediment felt by a user of the bed in normal use; wherein in an inflatable condition the inflatable body elevates the position of the mattress or portions thereof relative to the bed base to allow removal and replacement of bed linen such as bed sheets substantially without having to physically lift the mattress.

A system for a collapsible reclining bed and chair that comprises a rectangular central structure having four vertical sides comprising four telescoping legs supporting a rectangular mid-section seat. A pair of folding leg supports rotatably connected to the central structure by hinges, with each of the pair of folding leg supports comprised of at least one sliding bracing member attached to each of the pair of folding leg supports and a frame of each of the pair of folding leg supports deposed with the bracing member so as to lock in place when the associated folding leg support is fully extended. A back section connected opposite from the pair of folding legs by hinges able to rotate from a 0 vertical angle when closed to at least a relative 135 reclining angle when opened, and comprising a horizontal frame with a pair of telescoping legs extending downward. The collapsing and folding reclining bed converts into a closed or open configuration.

An adjustable bed base has a subframe which may be raised and lowered relative to a stationary frame by primary linear actuators. A deck is attached to the subframe. The deck may be flat or fully articulated depending upon the position of secondary linear actuators which are a part of a subframe module. The subframe module may be secured to the stationary frame of the adjustable bed base. The deck may be inclined by extending one of the primary linear actuators more than the other regardless of the positions of the deck members.
