【Triple Functionality | Comfortable and Relaxing Experience】This electric lumbar support pillow integrates three basic functions: vibration massage, soothing heat therapy, and electrically adjustable padding. Vibration mode: Gently massages the lumbar muscles, helping to relieve tension and stiffness. Heat therapy mode: Provides continuous, soothing warmth for a truly comfortable experience. Electrically adjustable pads: You can adjust the support height according to your personal preferences, improving lumbar support and back posture. These three functions work together to make your rest and relaxation more comfortable. 【Ergonomic Design for Optimal Support】This lumbar pillow features an ergonomic 135° arc design that perfectly adapts to the natural curve of the lower back. The extended and widened structure envelops the lower back and hips, providing stable support even when changing sleeping positions or lying on your side. The built-in \"Air Cotton\" memory foam core has slow recovery properties (recovery time of approximately 5 seconds), effectively distributing pressure and eliminating the feeling of an \"unsupported\" lower back. 【Six Key Features for Lumbar Support】This product includes several design elements to enhance comfort: soothing heat therapy, dynamic vibration massage, adjustable support height, ergonomic curved design that adapts to the waist, and soft, comfortable material. We recommend using the pillow for about 30 minutes daily to help relax the body and improve overall comfort. 【Comfortable Fabric Suitable for All Seasons】The fabric uses breathable and moisture-wicking technology, soft against the skin, quick-drying and breathable, ensuring a comfortable experience all year round. Using the heat therapy and massage functions after exercise or long working hours can provide a deep relaxation and rejuvenation experience. 【Easy Operation】Press and hold the on/off button: Turn on/off. Automatic mode: Switches between vibration, water filling, and heat therapy modes. Manual mode: Flashing blue light: Vibration mode; Green light: Filling adjustment mode; Red light: Heat mode. Note: This product is an electrical device and requires a power source to operate. 【Wide Range of Applications】Suitable for various environments, including offices, home relaxation areas, reading nooks, and travel, providing a comfortable experience for those who sit for long periods or need extra lumbar support.
