[Enjoy a comfortable, zero-gravity sleep!] This innovative, high-performance gel material creates a zero-gravity sleeping experience, as if you're floating in the air! The durable, flexible, and resilient gel material conforms perfectly to the shape of your neck and head, redistributing body pressure. This highly durable material is resistant to deterioration even after 10 years. It's completely washable, so you can always keep it clean. (Note: Only the main unit is washable; the height-adjustable sheet cannot be washed.) The non-slip bottom helps maintain a stable sleeping position. [Special 3D structure supports ideal sleeping posture] Ventilation holes in the upper and lower layers prevent stuffiness and provide excellent breathability. The special ergonomic 3-layer lattice structure instantly conforms to the shape and position of your head, allowing for a comfortable sleeping position. [A custom-made fit! Pursuing the perfect fit in 1cm increments] Three height-adjustment sheets with different thicknesses (1cm, 2cm, and 3cm) allow for 9 height adjustments from 4cm to 12cm in 1cm increments. Like a custom-made pillow, these precise adjustments allow you to find the perfect height for you. The pillow's height is different on each side, allowing you to choose the height that best suits your needs. The height is also recommended for side sleepers. [Reliable low-formaldehyde specifications & confident quality! 1-year warranty] - The odor-resistant outer cover ensures cleanliness and comfort. Low-formaldehyde specifications ensure safe use for children. The height-adjustable seat is made of urethane, so it may have an odor immediately after opening. However, if you dry it in a well-ventilated place in the shade, the odor will decrease to an unnoticeable level within a few days to a week. A 1-year warranty provides support in the unlikely event of a malfunction.
