The IFMC. Bed Pad (International Model) can be expected to have various effects such as promoting blood circulation, relieving fatigue, easing muscle tiredness and stiffness, alleviating neuralgia and muscle pain, and improving sleep, allowing you to spend a comfortable sleeping time. When you sleep on it, you can expect a sensation similar to that of soaking in a hot spring. When you wake up the next morning, you will likely feel a difference in your fatigue recovery, lower back pain, stiff shoulders, and body stiffness. You can also achieve similar effects by layering your existing bed pad over the IFMC. Bed Pad.
