2D S-Track
🌟 Customer Favorite
The popular Osaki OS-4000T is a full function massage chair that automatically detects the natural curvature of the human body and adjusts the massage to fit. The Zero Gravity position elevates your legs above your heart and more evenly distributes your weight. The OS-4000T also features a full body air massage, seat vibration, heat therapy, 8 automated programs, new foot rollers and more. Sit back and enjoy one of our best sellers.
Ergonomic S-Track Massage
The Osaki OS-4000T’s quad roller mechanism follows the natural S-shaped curvature of your spine with a consistent massage pressure.
Many massage chairs are designed with an uncomfortable straight track which applies an intense massage in the mid-back area and poorly targets the neck and lower back regions. With the OS-4000T’s sophisticated S-Track design, however, you can expect a uniform, hand-like massage along the neck, shoulders, mid and low back. In total, the OS-4000T’s roller system measures 30″ in length.
2-Stage Zero Gravity
Inspired by NASA technology, Zero Gravity is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into Zero Gravity, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. There are two stages of Zero Gravity, the 2nd being more reclined, relative to the seat base.
Zero Gravity relieves pressure on the spine, relaxes the neck and back, increases blood oxygen levels, expands lung capacity, and helps correct spinal alignment. When reclined such that your legs are positioned higher than your heart, the therapeutic effects are incredibly effective and may be felt immediately.
New Feature
Reflexology Foot Rollers
There are two rows of spinning reflexology massagers which apply a soothing, kneading style application to the bottom of the feet. As the rollers spin, they stimulate the feet’s acupuncture points.
Additionally, airbags inflate in a downward motion onto the sides of the feet, pushing them into closer contact with the foot rollers.
Computer Body Scan
The Osaki OS-4000T scans your body prior to the massage to customize it specifically for your body type and size. This translates into a more precise massage that hits all the key areas. Plus, you can make micro adjustments as needed to bring a more humanistic and scientific massage approach.
Lumbar Heat Therapy
The Osaki OS-4000T’s lower back region features two heating pads to enhance your massage experience. Research has shown that lumbar heat therapy provides relief to those suffering from lower back pain. It does so by increasing the body’s oxygen flow, which in turn plays a role in healing damaged tissue. Heat therapy also forces your lower back to press more firmly against the backrest for a stronger and deeper massage.

38 Airbags
Osaki has re-engineered and developed the next generation of air massage technology. The OS-4000T includes 38 airbags that effectively compress against your body and mimic the feeling of being pampered by a masseuse.
Airbags are located in the head & neck, outer shoulders, arms, buttocks & thighs, waist, calves, and feet. The combination of the back rollers and airbag system makes the OS-4000T a full body massage chair — covering everything from your head all the way down to the bottoms of your feet.
Arm & Hand Airbags
The OS-4000T features a durable spandex pocket which inflates to compress above and below your arms and hands with multiple airbag units.
Shoulder, Lumbar & Hip Squeeze
In the upper to mid portion of the chair, airbags are programmed to inflate at independent times, causing your body to twist, creating an enjoyable stretch. Stretching is also applied to your shoulders, lower back, hips, and thighs.
Foot & Calf Airbags
The OS-4000T features 14 airbags that inflate and compress against your calves and feet. In addition, spinning rollers target your foot soles, applying a concentrated pin-point kneading massage.
8 Auto Programs
Choose from five expertly crafted full body automatic programs, including Muscle Relief, Thai, Stretching, Anti-Stress, and Demo. There are also two localized programs for the Neck/Shoulder and Back/Lumbar. For just an airbag compression massage, select the Full Air mode.
6 Manual Techniques
Create your own custom program and choose from six massage roller techniques, including Kneading, Tapping, Clapping, Rolling, Swedish, and Shiatsu.
Easy to Use LCD Display Remote
The Osaki OS-4000T remote — which sits on a pedestal stand — boasts one of the largest viewing screens to easily visualize what functions the chair has activated. There is also a flip down cover to access the manual functions of the chair. The remote allows you to select the massage type, intensity, speed and location.
Mini Wireless Remote
Attached to the main remote you will find a compact wireless controller. This will allow you to control the main functions of the chair without having to struggle to reach the main display panel while reclined.
Seat Vibration
Located in the seat base is a vibration plate that applies a soothing vibration massage to the back of your thighs and buttocks.
Auto Leg Scan
The footrest is capable of making adjustments according to your unique leg length. This ensures that the massage airbags are concentrating on the correct areas. At the start of the massage, the footrest will fully extend out and then retract. Once it has reached your desired length, firmly press down along the toes to indicate to the footrest to stay in that position.
