Curbside Delivery ships via Freight to the 48 contiguous states. The freight company will deliver your massage chair to a carport or first-floor entryway. Please check the box dimensions and ensure it will fit through your doorway. Assembly is required and can take 30-90 minutes, depending on the chair.

In-Home Delivery ships via Freight to the 48 contiguous states. The freight company will deliver your massage chair inside your home (no stairs) just inside the doorway. Please check the box dimensions and ensure it will fit through your doorway. Assembly is required and can take 30-90 minutes, depending on the chair.
In-Home Delivery and Assembly – Avg. Shipping Time 10-20 Business Days
In-Home Delivery and Assembly is the same as White Glove Delivery. Your massage chair will be shipped via Freight to the White Glove Delivery warehouse. They will contact you to schedule a delivery time and date when they receive your order.
The White Glove Delivery team consists of a two person installation team that will deliver (up to 2 flights of stairs), unpack, and install your massage chair in your room of choice. These are not professional massage chair installation experts but a furniture installation team. They may or may not have installed your massage chair model before.
Massage chairs are heavy, so make sure you have some extra help to move the boxes and help in assembly.

Osaki Duke XL 4D Massage Chair
The Osaki Duke XL 4D Massage Chair is engineered specifically for taller and larger users who want full-body recovery without compromising comfort or durability. Built on an oversized reinforced frame, this XL massage chair supports up to 400 pounds and fits users up to 6’8”, combining advanced 4D roller technology, extended SL-Flex track coverage, and deep compression therapy for structured, customizable relief.
Massage Technology
-
Advanced 4D Massage Mechanism
The Osaki Duke XL features a true 4D massage mechanism that adjusts depth, speed, and rhythm in real time. Unlike basic 3D systems, the rollers can move in and out with variable cadence, allowing deeper tissue engagement and more precise pressure control. Intensity can be adjusted to match user preference, whether you need a lighter recovery session or deeper muscle work.
-
SL-Flex Track for Extended Coverage and Stretch
The SL-Flex Track follows the natural curvature of the spine from the neck and shoulders down through the lower back and upper glutes. Its flexible design maintains consistent contact while reclining into zero gravity or near-flat positions. This extended track improves stretch programs and allows for more effective spinal decompression-style sessions.
-
Automatic Body Scan System
Before each session, the Duke XL performs a body scan to detect shoulder position and back curvature. The rollers automatically adjust height and depth to ensure proper alignment along the spine, improving consistency and comfort.
-
48-Cell Full-Body Air Compression
The Osaki Duke XL 4D Massage Chair uses 48 strategically placed air cells located at the shoulders, arms, calves, and feet. These airbags apply rhythmic compression to support circulation, reduce muscle fatigue, and complement the roller massage for full-body recovery.
-
Deep Calf Compression with Targeted Bumpers
Four calf massage bumpers work with 14 air cells to provide focused compression to the lower legs. This design helps reduce tightness and improve circulation after long hours standing or sitting.
-
Triple Foot Rollers with Heat
Three specialized foot rollers stimulate the soles using reflexology-style ridges. Adjustable roller speed allows you to control intensity, while integrated foot heat enhances muscle relaxation during compression and rolling.
Features
-
Oversized XL Frame for Larger Users
The Osaki Duke XL is built with a reinforced steel structure, widened seating area, and extended backrest to comfortably support users up to 6’8” and 400 pounds. Wider armrests and expanded calf massagers ensure proper alignment and comfort without feeling restrictive.
-
Zero Gravity Recline
The zero gravity position elevates the legs above heart level to distribute body weight more evenly and reduce spinal compression. This position enhances roller effectiveness and improves relaxation during longer sessions
-
Touchscreen Tablet Controller
An integrated touchscreen tablet allows intuitive control of programs, intensity, air compression, heat, and recline settings. The interface supports multiple languages and provides clear visual feedback during operation.
-
Heating Shawl Therapy
Targeted lumbar and foot heat is built into the chair, and the included heating shawl can be placed over the chest or abdomen. This layered thermal approach supports muscle relaxation and improves overall comfort during deep massage sessions.
-
Spring-Loaded Extendable Footrest
The footrest extends up to 7 inches using a spring-loaded mechanism, automatically adjusting to accommodate different leg lengths and ensuring proper positioning for taller users.
Massage Programs
-
Intelligent Health Detection System
The Osaki Duke XL includes an AI-powered health monitoring system that measures fatigue levels, heart rate, blood oxygen, microcirculation, and heart rate variability. Based on these readings, the chair adjusts massage intensity and program selection to better match your body’s current condition.
-
20 Automatic Massage Programs
Twenty preset programs are divided into full-body sessions, targeted pain-point routines, sectional massages, and relaxation modes. This structure makes it easy to choose a program based on recovery goals, time availability, or specific muscle tension.
Additional Features
-
Built-In Armrest Shortcut Controls
Quick-access control panels located on the armrests allow users to adjust recline angle, activate zero gravity, or change programs without using the tablet.
-
Bluetooth Audio System
High-quality Bluetooth speakers allow you to stream music, podcasts, or guided relaxation audio directly from your device during sessions.
-
USB-C Charging Port
A built-in USB-C charging port keeps your smartphone or tablet powered throughout your massage, eliminating the need to leave the chair mid-session.

Osaki Duke XL 4D Massage Chair – FAQ
-
Who is the Osaki Duke XL 4D Massage Chair designed for?
The Osaki Duke XL 4D Massage Chair is built for taller and larger users who want more space and stronger support. It features an oversized reinforced frame designed to accommodate users up to 6’8” and up to 400 pounds while maintaining proper roller alignment and comfortable fit.
-
What does 4D massage mean on the Duke XL?
4D massage adds variable speed and rhythm control to the roller movement, on top of the in-and-out depth and up-and-down tracking found in 3D systems. On the Duke XL, this allows the rollers to change pressure and cadence during a session for more controlled deep-tissue work and more natural-feeling transitions.
-
How far does the SL-Flex track massage coverage go?
The SL-Flex track is designed to follow the spine from the neck and shoulders down through the lower back and into the upper glute area. This extended coverage supports full-spine massage sessions and improves stretch-focused programs, especially when combined with deeper recline positions.
-
Does the Osaki Duke XL use a body scan?
Yes. The Duke XL includes automatic body scan technology to detect your shoulder position and back curvature before each session. The chair then adjusts roller height and depth to improve alignment and deliver more consistent contact along the spine.
-
Where are the airbags located and what do they do?
The Osaki Duke XL 4D Massage Chair uses 48 air cells positioned at the shoulders, arms, calves, and feet. The air compression system applies rhythmic pressure designed to support circulation, reduce muscle fatigue, and complement the roller massage for a more complete full-body session.
-
What is the Intelligent Health Detection feature used for?
Intelligent Health Detection measures wellness metrics such as fatigue level, heart rate, blood oxygen, microcirculation, and heart rate variability. The system uses those readings to help tailor program selection and intensity so sessions better match how your body feels that day.
