Transform your usual bed into a space for restful sleep. A dome-shaped pillow that you put over your head to sleep, incorporating the three key elements for good sleep. The "IGLOO" sleep pillow solves problems such as difficulty falling asleep after getting into bed and being bothered by light leaking through curtains in the morning or after night shifts. Co-developed with sleep specialists, it features a dome-shaped design that incorporates the three essential elements for comfortable sleep: "light blocking," "moderate sense of enclosure," and "reduction of surrounding noise." By placing your usual pillow inside and covering your head, it envelops your face, allowing you to sleep in a calm environment. It supports a smooth transition into sleep. I purchased and opened it, but I didn't use it, so I'm putting it up for sale. I hope someone will use it.
