2D S-Track

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.

Osaki OS-4000T Features

Osaki OS-4000T Massage Chair S-Track

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.
Osaki OS-4000T Massage Chair Foot Rollers
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.
Osaki OS-4000T Massage Chair Body Scan

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.
Osaki OS-4000T Massage Chair Heat Therapy

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.
Osaki OS-4000T Massage Chair Arm Airbags

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.
Osaki OS-4000T Massage Chair Lumbar and Hip Squeeze

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.
Osaki OS-4000T Massage Chair Foot Airbags

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.
Osaki OS-4000T Massage Chair Auto Programs

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.
Osaki OS-4000T Massage Chair Manual Techniques

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.
Osaki OS-4000T Massage Chair Seat Vibration

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.
Osaki OS-4000T Massage Chair Auto Leg Scan

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.

Fine Tuning

Adjust the Airbag Intensity, Roller Speed, Roller Width, Localize the Massage & More
  • Airbag Intensity: The intensity of the airbags can be controlled up to 5 levels, from mild to strong.
  • Roller Speed Adjustment: The speed in which the massage heads move can be controlled up to 5 different levels, ranging from slow to fast.
  • Roller Width Adjustment: Choose from three options: Wide, Medium & Narrow. If you want the massage heads to concentrate on the outer shoulders and outer back, choose the wider option. If you want the massage heads to be closer together near the middle of the back, choose the narrower option.
  • Localized Massage: Prefer to target a specific area of the spine? Choose Partial to focus the rollers within 3 inches of a specified point or Spot to focus on a specific area.
  • 30 Minute Timer: 5-30 minutes of usage can be programmed. The duration of the massage can be increased or decreased in 5 minute increments.

More Durable Upholstery

The Osaki OS-4000T features updated upholstery not found in the previous model, the OS-4000. The improved synthetic leather material is designed to be more breathable and durable than its predecessor.

Shipping Methods

Curbside Delivery

All massage chair orders qualify for free Curbside Delivery. Your order will be left on your curb or near your entryway after you accept delivery. The delivery driver will not bring your chair into your residence. Massage chairs are heavy and we recommend having another person or two on hand to help carry the box(es) inside. A dolly or hand truck can also be a helpful method of hauling the chair inside. Depending on the chair you are purchasing, your order may arrive unassembled. Assembly instructions are included in your chair's packaging and most models can be installed in under an hour. | Approximate Delivery: 1-2 weeks

Threshold Delivery - $75

The delivery driver will place your order at the first dry area available, such as inside a garage, near your entryway, inside a front door, or underneath a carport to ensure protection from the elements. This delivery method does not include room of choice delivery, assembly, unboxing, or debris removal. | Approximate Delivery: 2 weeks

In-Home Delivery & Set Up - $179

Your order is delivered directly to a third party agent. Shortly after the agent receives your order, they will call you to coordinate a delivery window. On that date, they will carry your massage chair box(es) inside the room of your choice (up to two flights of stairs), unbox, and assemble your chair. Note that in smaller markets, the third party agents are not necessarily experts in assembling massage chairs and we highly recommend opting for one of the other two shipping options if at all possible. | Approximate Delivery: 2-3 weeks

Please allow approximately 2-4 business days for orders to process and ship.

    Best Investment

    I give the Osaki chair a 5 star, along with the customer service gentleman. This is what I needed to help relieve lower back, shoulder and neck pain. Good investment!

    The features of the chair are great but the shoulder housing can be tight if you have wider shoulders.

    My health❤️

    I have a very hard job. My back, shoulders and arms hurt a lot. I went to doctors. Only pills were offered. I bought a chair and use it every day after work. Back pain decreased, it became easier to work my hands. thanks 🙏🙏👍🥰💃

    Mom uses it daily!

    I bought this massage chair for my mom. She is frequently sore from work and this chair has been a huge blessing to her. She uses it every day after work to help her muscles relax. She also has some nerve pain problems in one leg and one arm, and the chair has helped to relieve tension in those muscle areas which has decreased some of her nerve pain. My dad uses it a few times a week as well. This chair was a great investment that has been a blessing to my parents!

    Pretty good

    Pretty good chair for the value. Well positioned for hitting my aches in my back. However, there is no good spot for my colostomy bag. I thought it would rest on the arm, but it fell due to the vibrations and broke on impact making quite the mess on the upholstery on the side of the chair. It cleaned up after a little work.
