The nails are equally spaced on the bed. When our body is lying on the nails, the pressure due to the weight of the body is equally distributed throughout the body over a wide surface area. The weight of our body is supported by the equally spaced nails present on the bed. The equally spaced nails support uniformly all parts of the body. This prevents the body from being hurt.
