Zero-pressure memory foam combined with targeted USB heat therapy penetrates 2–3cm into cervical tissue to relieve chronic neck tension and promote muscle relaxation.
Targeted thermal therapy increases cervical blood flow for faster tension and stiffness relief
Zero-pressure memory foam distributes weight evenly to eliminate pressure point discomfort
Sustained USB heat maintains consistent therapeutic temperature vs. cooling chemical packs
Reduces cervical stiffness linked to forward head posture, desk work, and screen fatigue
