THREE-IN-ONE SOFA BED

摘要

A three-in-one sofa bed including a bedstead assembly; a sofa cushion and sofa seat assembly fixedly connected to the bedstead assembly; a moveable coffee table; a mattress and mattress frame assembly a proximal section of which is pivotably connected to a rear section of the bedstead assembly to enable the mattress and mattress frame assembly to be rotated with respect to the bedstead assembly between a horizontal position and a vertical position. In the horizontal position, the mattress and mattress frame assembly straddles the sofa cushion and sofa seat assembly and the movable coffee table to form a bed. In the vertical position, the sofa cushion and sofa seat assembly and the movable coffee table are exposed. Balance weights are provided for the mattress frame between adjacent pulley grooves, to make torque in front of central axes of the pulleys be equal to that behind the central axes.
