This massager will massage your trap muscles, you can pretty much use it anywhere. just keep in mind it's not made for you to lean back and put weight on it, because that could burn the motors, no laying on it or leaning back on it. If you lean back on it, barely do it, just to make sure it lasts you a long time 😊 if you use it upright, it massages your neck, if you turn it upside down and use it, it will massage your trap muscles.
