Sitting or lying down in bed for a long time inevitably leads to pain in the buttocks. This cushion was created in response to customer feedback that it completely lifted the tailbone when sitting. - The shape of the mattress lifts the sacrum, which is prone to bed sores, reducing body pressure and stress. - The tailbone is completely lifted. The separation ensures that the sacrum, which is prone to bed sores, does not touch the cushion. Also, the cushion is thick enough that you don't have to worry about hitting the bottom. - Thickness can be adjusted front to back. By moving the beads, the thickness can be adjusted front to back to suit the user's condition. - You can adjust the size of the holes by pulling the strings on the left and right sides. - Always keep it clean. The cover is removable and easy to wash. - Use as a pillow when lying face down, as a back cushion, and as a neck pillow.
