About the Product [Innovative Neck Stretcher Pillow] This latest neck pillow, designed with ergonomics in mind, relaxes your neck and shoulders with just 10 minutes of use each day. It helps alleviate "tech neck" and, with continued use, aids in restoring the correct cervical curve. [Ergonomic Neck Relaxation] Utilizes the weight of your head for natural, all-around neck stretching. The unique V-shaped indentation design gently fits and firmly supports your neck. The raised protrusions effectively relax both sides of your neck. [Countermeasures for Neck and Shoulder Fatigue] Prolonged sitting or incorrect posture during work or study can easily lead to neck problems. This neck stretcher relaxes tech neck and neck fatigue. [Dual-Sided Use] It typically takes 1-3 days to get used to this pillow, as it requires time to adapt to the user's neck contour. Until you get used to it, place your head on the protrusion side for gentle stretching. Once accustomed, place your head on the stretching side for comfortable extension. Neck Pillow Specifications: Size: (Approx.) 25cm (L) x 23cm (W) x 10cm (H). Made of polyurethane material, with a soft surface that offers excellent elasticity and resilience.
