An adjustable bed includes a fixed frame, an articulating frame supported on the fixed frame, first and second leg assemblies, and first and second actuators. The leg assemblies are configured to raise and lower the fixed frame between a lowered position and a raised position. The actuators are disposed and fully maintained within an interior volume of the fixed frame. The first actuator is fixedly secured at a first end to the head end of the fixed frame and operably coupled to the first leg assembly at a second end. The second actuator is fixedly secured at a first end to the foot end of the fixed frame and operably coupled to the second leg assembly at a second end. The first and second actuators are configured to exert a pulling force to raise the fixed frame and to exert a pushing force to lower the fixed frame.
