Fuji Latex released "S-sleep," Japan's first pressure-dispersing pillow that uses water pressure and a secondary curved surface. The shape can be freely changed according to the shape of the user's head, and the height can also be changed by adjusting the amount of water. It is said to be comfortable to sleep as if one is surrounded by water, taking advantage of the fluid characteristics. The standard type is priced at 6,000 yen excluding tax.

The bedding industry is experiencing a boom in "pressure dispersion" bedding using low/high resilience materials, but this product, by taking advantage of the characteristics of water as a fluid, disperses/absorbs the burden on the head, neck, and shoulders better than pillows made of low/high resilience materials, and provides a comfortable feeling as if you are surrounded by water.

Comfortable sleeping comfort is achieved through the application of fluid dynamics called "Pascal's Principle.

In addition, the structure applies hydrostatics to support the cervical vertebrae and jaw area with moderate pressure as water flows under the weight of the sleeper's head. The pillow also transforms to a shape that suits the sleeper's body even when the sleeper repeatedly turns over in bed.

The entire surface of the product is made of polyurethane, which is similar to the texture of human skin. It is said to be gentle on the skin and comfortable to the touch. In addition, the fine fibers of the polyurethane evaporate a small amount of water, and the cooling effect of the heat of vaporization allows the user to experience a coolness that cannot be felt with a simple water pillow.
