Driving can be stressful on your neck and upper back, especially without proper head and neck support. A neck rest pillow for car is specifically designed to provide ergonomic support while driving. These pillows attach easily to the car headrest and are usually made with memory foam or high-density fiber to offer the right blend of comfort and firmness.Some car neck pillow models also come with adjustable straps, making them compatible with most vehicle seats. This simple addition can reduce neck strain, especially during long drives or while stuck in traffic.
