Prolonged sitting, incorrect posture during work or study can easily lead to neck problems. Stretching the neck can relieve neck and shoulder stiffness. 【Ergonomic Neck Relax Pillow】■ Structure of the protruding surface: The slope of the protruding surface maintains a 35-degree angle, with an ergonomic curve that fits perfectly to the curve of the neck. ■ Load capacity: Designed with a U-shape to evenly distribute weight, significantly improving load capacity and making it less prone to deformation. ■ Number of acupressure protrusions: 10 protrusions firmly press the neck and back. They relax the muscles on both sides of the neck well. ■ V-support design: The unique V-shaped indentation design gently fits the neck, firmly securing and supporting it. 【Double-sided Use】Designed with ease of use in mind for beginners, the pillow can be used on both sides. You can adjust the height and stretch intensity of the pillow to suit your needs. It usually takes 1-3 days to get used to this pillow, as it takes time for it to adapt to the user's neck contour. 【Unisex & Ideal for Gifts】Made of polyurethane material, with a soft surface and excellent elasticity and toughness.
