Pillow [Improved breathability, freely adjustable height, with gusset] Hotel-style large pillow, high-rebound, with cover, popular, washable cushion,

[Gusseted & Three-Dimensional Structure] This high-rebound pillow with a gusset quickly recovers its shape even after a full night's sleep and resists flattening. The hotel-style pillow's three-dimensional structure conforms to the curve of the cervical spine, improving sleep quality and efficiency, allowing you to sleep soundly until morning. The high-density, high-rebound urethane slowly sinks in according to the weight and pressure of your head, changing shape to distribute and absorb pressure on your head and neck, preventing neck pain. It comfortably accommodates various sleeping positions, whether you sleep on your side or on your back. [High Rebound & Height Adjustable] This pillow uses high-rebound urethane material to firmly support your head and is very low, with a height difference of approximately 5 cm. By opening the zipper on the side, you can adjust the height of the pillow to suit your preference and physical condition. [Bamboo Fiber - Enhanced Breathability] This pillowcase is made from 100% bamboo fiber, offering excellent breathability and moisture absorption. It's cool in summer, comfortable in winter, and less prone to static electricity. Natural bamboo fiber boasts 3 to 5 times the breathability of cotton, and its unique fiber structure provides superior water absorption and moisture release. Thanks to the properties of bamboo, you won't have to worry about friction on your skin or hair when you turn over in your sleep. [Cooling and Contact Cooling Function] The pillow cover uses different materials on both sides. The surface is made of polyester and polyethylene, and its mesh or hollow structure provides a cooling function. For hot, sleepless nights, a pillow with a contact cooling function is recommended. Using a cooling pillow helps create a cool environment. It supports comfortable sleep throughout the year and reduces discomfort caused by night sweats. The pleasant feel delivers a luxurious sleep experience, just like in a hotel. [Cover Included, Machine Washable] Using this dedicated pillow cover effectively prevents daily dirt from penetrating the pillow itself. Protect A Pillow: The surface that touches your skin is made of 100% bamboo fiber, making it gentle on the skin, and the back is made of polyester and polyethylene, so it does not allow sweat and sebum stains to pass through, keeping it clean. When using a washing machine, put the pillow cover in a laundry net. This will help prevent friction and tangling with other laundry and reduce the amount of fabric that gets damaged.
