Sleeping on your back or side, if your posture changes, the required height will also change. Do you sleep on a pillow?

Air pads (elevation pads) are placed inside both the left and right sides of the pillow, and the pillow rises and falls according to the weight shift when lying on its side. The pillow adjusts the required height when lying on your back and on your side, so you can maintain a sleeping position that puts less strain on your cervical spine. - Comfortably supports the head with a three-layer structure of comfortable material. 　(1) The pillow surface is made of a three-dimensional mesh with excellent cushioning and breathability, and the outer fabric is made of knitted fabric with good water absorption and quick-drying properties.　 　(2) The inner material is made of flow beads with excellent breathability and fluidity, which moves according to the movement of the body to improve the fit. 　(3) The air cushioning of the elevation pad softly accepts the weight of the head when facing sideways, and increases support when lying on the back. - The flow beads of the inner material can be taken out from the zipper mouth of the inner bag, so it can be adjusted at the desired height.
