A foldable bed includes a first bed unit, a second bed unit rotatably connected to the first bed unit such that the bed is rotatable between a folded state and an unfolded state, and a stop unit arranged between the first bed unit and the second bed unit for preventing the first bed unit and the second bed unit from rotating relative to each other when the bed is at the unfolded state. The first bed unit includes a first support bracket and a first platform part supported on the first support bracket. The second bed unit includes a second support bracket and a second platform section supported on the second support bracket. When the bed is at the unfolded state the second platform section and the first platform section cooperatively form a platform of the bed for supporting a load.

A mattress 100 includes a movable part 1 and a mattress body 2 including a first mattress part 21 disposed above the movable part 1, and a second mattress part 22 provided separately from the first mattress part 21 and disposed to surround the first mattress part in a plan view. The first mattress part 21 is configured to rotate upward about the predetermined rotation axis by the movable part 1.

An armchair includes a base, a backrest pivotally connected to the base by a first rotating shaft, an armrest connected to the base and an elastic assembly fixed on the armrest. The backrest and the elastic assembly are pivotally connected by a second rotating shaft. The elastic assembly is configured to provide elastic force when the backrest swings around the first rotating shaft. The elastic assembly arranged between the backrest and the armrest permits the backrest to be able to swing relative to the base. In use, the elastic assembly controls the swing amplitude of the backrest according to the pressure exerted by the user's back on the backrest. When the user reclines backward, the elastic assembly acts as a cushion to support the backrest to slowly swing backward due to the elastic force. When the user rises, the elastic force of the elastic assembly urges the backrest to reset.

An adjustable bed including a base frame unit, a front bed frame unit and a lumbar support unit. The front bed frame unit includes a back board which is hingedly connected relative to the base frame unit, and which is convertible between a back normal position, where an end of the back board is proximate to the base frame unit, and a back elevated position, where the end of the back board is distal from the base frame unit. The lumbar support unit includes a lumbar support, and is movably connected to the base frame unit such that in response to movement of the back board to the back elevated position from the back normal position, the lumbar support is moved to a remote position from a close position relative to the back board.

There is provided a backrest pivoting system having a backrest and an actuator for pivoting the backrest. The actuator is pivotably connected to the backrest by a pivot defining a first pivot axis. The backrest is configured to pivot about a guide member which defines a second pivot axis coaxial with the first pivot axis. There is also provided a backrest pivoting system including an actuator and a resilient member mounted in series with the actuator. There is also provided an extendable user support assembly comprising a lower body support panel and a core support panel supported by a frame, the lower body support panel being translatable relative to the frame such that an opening is created between the lower body support panel and the core support panel when the lower body support panel is translated away from the core support panel. There is also provided a method for placing a bed in a vascular position.

A mattress support includes a base plate configured to be positioned on a box spring of a bed. A bladder may be coupled to a top surface of the base plate. A top plate is coupled to a top surface of the bladder. A top surface of the top plate is configured to support a mattress. The bladder is inflatable to adjust a height of the top plate.

A foundation for a bed system can include an actuator, a deck mechanism operably related to the actuator so as to be actuated between raised and lowered positions in response to actuation by the actuator, and a controller operably connected to the actuator and configured to drive the actuator to actuate the deck mechanism between a lower position and an upper position. The deck mechanism can be configured to move to a service position that is further than the upper position. The deck mechanism can expose and permit access to a serviceable component when the deck mechanism is in the service position. A method of using a foundation having a service position is also described.
