Based on customer reviews on Amazon.com, the LiBa Shiatsu Neck & Back Massager Pillow is the best choice as of August 2015. Other high-ranking products include the HoMedics and the Zyllion Shiatsu Massage Cushions.
The LiBa Massager is portable and includes a heating function and automatic timer. Both the HoMedics and Zyllion cushion models also include heating functions. Unlike the LiBa, which is a smaller device for use on one area at a time, the HoMedics and Zyllion cushion models offer full back and neck massage options, as well as targeted options.
Several reviewers complained the LiBa massager was too bulky, given the company’s claims of portability. Some complaints about the HoMedics and Zyllion cushion models focused mainly on adjustability issues for people of different heights.
