Provided is an elevated bed system comprising a platform and one or more legs detachably connected to the platform. The legs may be configured to vary in length and may include a foot pivotably connected to each leg, enabling stable placement on various surfaces. The platform can be perforated and foldable. The system may also include configurations with multiple legs of different lengths and detachable, pivotable connections between the foot and the leg. Additionally, the system may encompass legs with portions designed to be secured to surfaces using stakes, screws, corkscrews, or combinations thereof. This versatile design allows for easy assembly, adjustment, and stability on diverse surfaces.

A swivel castor arrangement for a piece of furniture comprises: a holder; a swivel castor including a wheel mounted rotatably about a first axis on a frame mounted rotatably about a second axis on the holder; and a U-shaped bracket having a web connecting two legs attached rotatably about a third axis. The bracket is pivotable about the third axis between first and second positions and is movable into the second position when the first and third axes are substantially parallel. The wheel is arranged in the second position between the bracket legs such that free rotation of the frame about the second axis is restricted, and the wheel in the first position is not arranged between the bracket legs such that free rotation of the frame about the second axis is possible. The bracket is pivotable by less than 90 to switch between the first and second positions.

A width-adjustable foldable bed includes a main bed frame unit that includes a first bed frame subunit and a second bed frame subunit. The second bed frame subunit is pivotable relative to the first bed frame subunit to fold the main bed frame unit from a bed flat state, where the first bed frame subunit and the second bed frame subunit are arranged in a lengthwise direction, to a bed folded state, where the first bed frame subunit is stacked on top of the second bed frame subunit. Two lateral bed frame units are connected to two lateral sides of the first bed frame subunit and the second bed frame subunit. A backrest actuating device is connected to the first bed frame subunit, and is operable for driving the first bed frame subunit to switch between a first flat state and a first bent state.

An electric lifting bed is provided, which includes a bed frame, a fence and two sets of lifting assemblies respectively connected to a head and a tail of the bed frame. Each set of lifting assemblies includes two lifting bed legs and screw nut assemblies in the two lifting bed legs. The electric lifting bed further includes at least one driving motor, at least one motor cover plate and at least one shielding plate. The motor cover plate covers the driving motor, the shielding plate is connected with the bed frame and used for shielding the lifting assemblies, the driving motor and wiring harnesses arranged on the bed frame. The electric lifting bed can prevent the wiring harnesses, wiring harness connectors, transmission rods of the lifting assemblies and the driving motors from being exposed, ensuring good safety during use, and making maintenance of wirings simple and convenient.
