Infinity IT-9800 — A Massage Chair Built for Sharing, Sized for Everyone
The Infinity IT-9800 is a zero gravity massage chair with quad rollers and a decompression stretch. The Infinity IT-9800 looks as good as it feels, combining quad rollers with an invigorating decompression stretch in a single chair. It's built with a unique combination of features ideally suited for households, offices, or wellness spaces where the chair gets shared between family members, co-workers, or clients — and it's engineered to comfortably fit a wide range of body sizes, including wider bodies.
Wellness & Recovery Benefits of the Infinity IT-9800
-
An invigorating full-back stretch. The Decompression Stretch and True Inversion on the near-flat reclining S-Track gently lengthen the body, helping you feel looser and supporting flexibility and mobility.
-
Recovery for tired muscles. Quad rollers on the 2D mechanism knead, roll and work shiatsu along the natural curve of your spine, easing post-workout soreness and everyday stiffness.
-
Warmth that goes deeper. Lumbar heat and the infrared 3-level heat function relax tight muscles so every technique feels more soothing.
-
Calm through gentle motion. The Combination Rocking/Yoga Function rocks and stretches at the same time, a soothing reset that supports stress relief and a clearer head.
-
Healthy circulation. Weightless zero gravity recline, seat and arm vibration and the kneading-and-swing foot and calf zones help keep blood flowing and legs feeling lighter.
