A sofa frame, a vertical support bar and an assembled sofa. The sofa frame includes two side boards, a face board connected between the front ends of the two side boards and a back board connected between the rear ends of the two side boards. The two side boards, the face board and the back board forms a detachable frame structure. Between the face board and the back board, a vertical support bar is connected. The rear side of the vertical support bar is fixed with a connecting piece. By fixing and connecting the connecting piece and the back board, the support of the back board is strengthened. The lower end of the vertical support bar is connected with a support leg to contact the ground. The sofa frame is a detachable structure, which can be disassembled for packaging and transportation, and assembled again later.

A folding bed, such as a sofa bed, with an assembly configured to counteract the gravitational forces acting on both a rotation of the main panel in relation to the frame and a rotation of the foot panel in relation to the main panel. A transmission may be used in the assembly to connect the first pivotal connection, where the main panel pivots with respect to the frame, to the second pivotal connection, where the foot panel pivots with respect to the main panel. The transmission transmits torque from the first pivotal connection to the second pivotal connection, so as to counteract gravitational forces acting on the foot edge of the foot panel.

The present disclosure provides a multifunctional cup holder for installation on a sofa and a sofa thereof. The cup holder includes: a base configured to attach to a sofa; a cup body; a flange disposed at an upper end of the cup body; and a control assembly disposed on the flange. A lower end of the cup body is attached to the base. The flange is detachable from the upper end of the cup body, and the flange extends radially inward towards a center of the cup body. The control assembly is removable from the flange and is configured to control operations of the multifunctional cup holder or adjustments of the sofa.

Sofa frame and assembled sofa, comprising back boards, side boards connected to back boards, and face board connected to side boards; said side boards are relatively configured on the two sides of the back board; the two sides of the face board are respectively connected to the side boards on both sides; said face board comprises at least two folding blocks and hinges connected to the folding blocks. In the above-mentioned sofa frame, as hinges are used to connect adjacent folding blocks, the face board becomes a folding structure. Thus, during transportation, the folded face board occupies less space to reduce transportation cost.

An intelligent bed includes a bed body, a plurality of sound receiving elements, a voiceprint database, and a controller. The plurality of sound receiving elements is surroundingly arranged around the bed body at intervals. The sound receiving elements each are configured to receive an audio signal from an audio source. The voiceprint database includes a plurality of contextual voiceprints. The controller is coupled to the sound receiving elements and the voiceprint database and configured to: extract a voiceprint of the audio signal; determine whether the voiceprint is consistent with one of the contextual voiceprints; and generate a status notification signal based on the voiceprint being consistent with the one of the contextual voiceprints.

A system that has a plurality of monitors, a control unit, a first object and a second object is provided. The second object has one or more sensors operable to generate data and is remote from the first object. The control unit is configured to determine whether a first user is positioned on a first or on a second location of the first object and display a simulation of a second user onto the plurality of monitors based on the generated data. The second user is located remote from the first user and is displayed as being positioned in a different location on the first object than the first user on the first object. The control unit is further configured to activate the one or more heat generating devices to simulate a presence of the second user being positioned in the different location on the first object.
