Anyone who suffers from back pain knows how debilitating it can be
and how difficult it is to find relief. The Human Touch® Gravis ZG Chair
combines the therapeutic benefits of zero-gravity with air massage
technology, multi-zone heat and powered positioning for every part of
the chair. With crisp, clean lines and innovative design, Gravis delivers
both neutral posture pain relief and exceptional control of your comfort.
Human Touch zero-gravity chairs recline while cradling your back and
elevating your legs above your heart. It is this therapeutic position that
doctors recommend as the healthiest way to sit. As the chair reclines, the
muscles immediately start relaxing. When the chair reaches zero-gravity
there is a major reduction in muscle irritation, which promotes spinal
health and relief from back pain.
Supported by millions of dollars and years of research, Human Touch
products are the only therapeutic chairs endorsed by the World
Federation of Chiropractic. To ensure that you don’t overlook any of your
chair’s features, and that you use it safely, read this manual carefully.
Then sit back, relax, and enjoy the many benefits of the Gravis ZG Chair!
For more than 35 years, Human Touch has established itself as an
industry leader that is changing the lives of its customers with products
and services that help them feel, perform, and live their best. Developed in
cooperation with the medical community and industry experts, we deliver
products that blend patented technology, craftsmanship and intelligent
ergonomics with superior design to enable therapeutic relief for everyone.
Our industry-leading massage chairs, Perfect Chair® recliners and
evolving set of innovative solutions share attributes in their ease-ofuse, attention to performance and quality, and design to adapt to most
any lifestyle. These attributes are highly valued by our customers and
garner broad industry award and recognition. As a result, Human Touch
