The Osaki 3D Quest (Model EC-1616) is a full-body electric massage chair featuring 3D roller technology that adjusts massage depth for a customizable, lifelike massage experience. The chair offers multiple auto massage programs targeting the neck, shoulders, back, and lumbar, with adjustable width and intensity settings to suit different body types.

The 3D rollers travel along an SL-track path that follows the natural curvature of the spine from the neck down through the glutes, delivering thorough coverage of the entire back. Zero-gravity recline positions the body to distribute weight evenly, reducing pressure on the spine and enhancing the effectiveness of each session. Full-body airbag compression covers the shoulders, arms, hips, calves, and feet, while a dedicated calf-and-foot kneading unit with foot rollers targets lower-leg tension and fatigue.

The chair includes a built-in touchscreen controller mounted on the armrest for easy program selection, speed, and intensity adjustments. Heat therapy is available in the lumbar region to help loosen tight muscles before and during massage. The beige upholstery is finished in a durable synthetic leather suited for home use.
