The Osaki Duke XL 4D is built for larger users. An oversized frame with a 26-inch shoulder width and 23-inch seat supports up to 400 lb and heights up to 6'8", so taller and bigger customers get the same full-body coverage as everyone else.

The 4D massage mechanism adjusts roller depth and angle for deep-tissue relief along an SL-Flex track, body scan technology sets it to your build, and intelligent health detection reads your condition to suggest a program. Twenty auto programs and five manual modes are managed from a touchscreen controller with shortcut panels on the armrest.

48 air cells compress the shoulders, arms, calves and feet, a heating shawl adds warmth across the chest and stomach on top of the usual lumbar heat, deep calf massage works the lower legs and three specialized foot rollers cover the soles. A spring-loaded footrest extends to fit long legs.

Zero gravity recline, LED lighting detail, a USB-C charging port and quality Bluetooth speakers finish a chair that finally fits the people most massage chairs leave out.

Size-Accommodating Chair

The Osaki Duke XL is precision-engineered for taller and larger users, featuring a wider frame and reinforced steel construction that easily supports up to 400lb. Its extended backrest fits individuals up to 6'8", while widened armrests and calf massagers provide added comfort and accessibility.

4D Massage Mechanism

4D massage mechanism enhances traditional 3D massage by adding adjustable rhythm and speed, allowing the rollers to vary intensity in real time. This creates a more lifelike, human-like massage that adapts to your body for deeper, more precise relief.

Intelligent Health Detection

The Osaki Duke XL is equipped with an advanced health monitoring system that measures key indicators such as fatigue level, heart rate, blood oxygen, microcirculation, and heart rate variability. Powered by AI, it uses these insights to automatically customize a massage experience tailored to your body's real-time needs.

SL-Flex Track System

The Osaki Duke XL elevates the traditional SL-track with an advanced SL-Flex Track that maintains a fixed angle to the backrest for greater adaptability and comfort. This innovative flexible track delivers full-body coverage from the neck and shoulders down to the upper glutes, enabling a deeper stretch massage.

48-Cell Air Compression Massage

Equipped with 48 strategically placed air cells, the Duke XL provides gentle, targeted compression that eases tension, enhances relaxation, and leaves you feeling fully rejuvenated.

Heating Shawl Therapy

The Duke XL utilizes advanced heating technology to deliver targeted warmth to the lumbar and feet, relieving muscle tension and enhancing deep relaxation. This chair also offers the option of placing the shawl over your body to target the chest and abdomen areas.

Zero Gravity Reclining

Zero gravity reclines the chair into a single, perfectly balanced position that elevates the legs and evenly distributes body weight to reduce pressure on the spine and enhance overall relaxation.
