Motorized bed and bed frame
Disclosed are motorized beds and bed frames. A motorized bed frame includes a lower frame and an upper frame disposed above the lower frame. At one or each of first and second sides of the motorized bed frame, the motorized bed frame also includes an actuating unit and a gearing unit to move and position an upper sub-frame of the upper frame with respective to the lower frame. The upper sub-frames at the first and sides can be independently positioned to meet individual needs. In some cases, the motorized bed frame includes additional or optional components to help dispersing the load and stabilizing the bed frame during operation.
