I never thought that a summer night pillow could change the perceived temperature like this. This Sunmmer cold sleeping memory pillow makes your fingertips remember coolness first from the first touch. Slow rebound memory foam, when you raise your head, it will slowly receive it, when you stand up, it will return to its position without rushing. It's like a pillow whispering “there's no hurry”. Butterfly-shaped design provides natural support for the neck and shoulders The name cervical pillow is not exaggerated; even when lying upright or on your side, your neck does not float in the air. Especially in summer, there was less of the usual sweaty feeling, so there was almost no dampness when touching the pillow in the morning. The memory cotton cover is also breathable, so you won't feel stuffy even if you toss and turn all night. The advantages are obvious Cool touch, stable support, and neck fatigue reduction effect can be felt. It feels like the quality of sleep has improved by a level. The downside is that due to its memory foam properties, there might be a slight material odor for the first few days, and those who prefer fluffy pillows might find it somewhat firm. Still, if you are the type who wants to persuade your neck and head at the same time in summer nights, this pillow is worth enough. Sleep is both a science and a feeling, this pillow quietly proves it.
