This inflatable travel neck pillow features a 45° golden angle design. It allows the head and neck to lean forward naturally, reducing pressure on the cervical spine, enhancing resting comfort, and helping users fall asleep faster and extend sleep duration during trips. Designed based on ergonomic principles, the neck pillow not only wraps around the neck but also maintains the normal positional relationship of the head, neck, and shoulders during sleep. It reduces damage to the cervical spine, sciatic nerve, and coccyx caused by poor posture, improving sleep quality. The neck pillow is equipped with a unique large-sized air valve, making inflation and deflation easier compared to ordinary inflatable neck pillows. It is recommended not to overinflate it during use, leaving some space will make the neck pillow softer. The product has a soft and comfortable touch and comes with a drawstring storage bag. It can be folded and placed in the bag, with a net weight of only 0.78 pounds, ensuring strong portability. The uninflated size of the neck pillow is 5.8x4.7x2.3 inches, and the inflated size is 19.6x11.8x11.8 inches. It is suitable for various scenarios such as office lunch breaks, airplanes, cars, buses, trains, and camping, supporting a good night’s sleep. Color: Black. Material: Foam.
