Why desk work destroys lower backs
Sitting isn't dangerous. Sitting in the same collapsed position for hours is. The lumbar curve flattens, the load shifts onto passive structures, and the deep stabilising muscles stop firing. By 4pm your back is holding a shape it was never designed to hold.
That is why the support component matters as much as the heat. The Triple Method Back Massager physically restores the lumbar curve while you sit, so the warmth and massage aren't fighting your posture.
