Free Curbside Delivery – Avg. Shipping Time 7-10 Business Days
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 – Avg. Shipping Time 7-10 Business Days
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.
Please contact us for a shipping quote if you live in Hawaii, Alaska, or Canada.

Osaki OS-Pro 4D DuoMax Massage Chair
The Osaki OS-Pro 4D DuoMax is a premium massage chair designed to deliver a personalized, spa-level experience in the comfort of your home. With dual 4D + 3D roller technology, an innovative SL Flex Track, intelligent health detection, and a full suite of customizable programs, it goes beyond relaxation to support recovery, circulation, and overall wellness.

Massage Technology
-
Duo Mech 4D+3D Massage Roller
The Osaki OS-Pro 4D DuoMax features a dual 4D + 3D roller system that mimics human touch, allowing for adjustable depth, speed, and intensity. A body scan maps your shape for precise relief, while quad rollers target both the back and lower body simultaneously to ease tension and stress.
-
Heated Duo Massage Rollers
The DuoMax features jade-core rollers that gently warm as they move, following the natural contours of your body. This soothing blend of massage and warmth helps release stiffness and promotes deeper relaxation.
-
SL Flex Track
Unlike a standard L-Track that stays in a fixed L-shape, the DuoMax’s Flex Track pivots with the chair as it reclines. This flexibility allows you to achieve a more natural lie-flat position, enhancing stretching and delivering a deeper zero-gravity experience.
-
Air Compression Massage
The 36 airbags are positioned throughout the chair, providing gentle compression to the shoulders, arms, hips, calves, and feet. Multiple intensity levels let you tailor the pressure for improved circulation, muscle relief, and total-body relaxation.
-
Armrest Massage
The DuoMax features a piano-style arm massager that gently cradles the forearms and hands with rhythmic pressure. By targeting arm tension, it enhances circulation and provides soothing relief.
-
Calf Rollers
The integrated calf rollers rotate and glide up and down to provide full coverage of the lower legs. This targeted motion improves circulation and eases muscle tension in the calves.
-
Calf Kneading
The leg rest of the Osaki OS-Pro 4D DuoMax rotates to mimic a kneading motion on the calves. This targeted movement relieves tightness, improves circulation, and provides deeper lower-leg relaxation.
-
Reflexology Foot Rollers
The foot rollers are designed with ridges that stimulate key acupressure points for deeper therapeutic benefits. With two rollers per foot, they deliver a full massage from heel to toe, easing tension and improving circulation.
Features
-
Space Saving Zero Gravity Recline
Inspired by NASA, the DuoMax’s Zero Gravity recline places you in a weightless position that relieves spinal pressure and enhances relaxation. Its space-saving design needs only 5.5 inches from the wall for a full recline, making it ideal for any room. Paired with the Flex Track, it delivers a true zero gravity experience that standard L-shaped tracks can’t match.
-
Heat Therapy
Soothing heat in the lumbar area and the heated shawl work together to relax tight muscles and ease tension throughout your body. This gentle warmth enhances circulation and deepens the overall effectiveness of your massage.
-
Automatic Legrest Extension
The footrest extends automatically up to 7.8 inches, adjusting to fit a wide range of user heights.
-
Touchscreen Tablet
The DuoMax features a full-color touchscreen tablet with an intuitive interface, making it as simple to use as your smartphone. Available in English and Chinese.
Massage Programs
-
Intelligent Health Detection
The Osaki DuoMax uses AI-powered health detection to track metrics like heart rate, blood oxygen, circulation, and fatigue. With this data, it adapts each session to your body’s current needs for a truly personalized massage.
-
Automatic Massage Programs
Choose from full-body or targeted massage programs designed for recovery, relaxation, or stretching. With the Flex Track, stretching routines feel more natural, while techniques like kneading, tapping, shiatsu, and 4D variations provide endless customization.
Additional Features
-
Armrest Controls
Convenient armrest controls let you adjust recline, zero gravity position, massage intensity, and more without reaching for the tablet. This quick access keeps you comfortable and in control throughout your session.
-
Voice Control
The DuoMax includes built-in voice control, letting you operate key functions completely hands-free. Just speak a preset command, and the chair responds instantly.
-
Bluetooth Speakers
Enjoy immersive sound during your massage with the built-in Bluetooth speakers. Stream your favorite music, podcasts, or calming audio directly from your device.
-
Negative O2 Ions
The negative ion therapy is designed to help reduce stress and support improved energy and overall wellness.
-
Wireless and USB Charging
Stay connected while you relax with built-in wireless charging and a USB port, keeping your devices powered throughout your massage.
