HoMedics Mobile Comfortâ„¢ Memory Foam Neck Pillow & Vibration Massager makes travelling more comfortable. A soft memory foam design provides support and comfort, while the invigorating vibration massage setting relaxes tense neck muscles. Two speeds of low or high allow for a customisable experience. A removable, washable cover means you can enjoy a fresh, clean pillow each time you travel. To power your massager, simply slip in 2 x AA batteries. As a bonus, a pair of ear plugs are included for added travel comfort.
