Lately, zero gravity has been one of the indispensable features in most of the massage chairs. It is quite an important feature as it enables the user to relax completely, by submerging him/her in an ideal position that gives them an ultimate massaging experience.
It works on the zero gravity concept which is commonly used by the astronauts for their massages. A massage chair with a zero gravity feature is more comfortable and easier to use when compared to the other massage chairs.
