Compared to Other Chairs

The Osaki OS4000T is the most affordable among the Katana 700 and Inner Balance Jin 2.0 massage chairs, while still offering a variety of features that models don’t have. Unlike the other two massage chairs, the OS4000T doesn’t have an L-Track design.

The Osaki OS4000T massage chair is a step above the Katana 700 and Inner Balance Jin 2.0 massage chairs in terms of safety features. It’s equipped with airbags in the neck and head area, providing additional support for your head during your massage session.

Katana 700

See Price
The Osaki OS4000T massage chair does not have the same features found in the Katana 700, including Bluetooth connectivity. However, it does have a few unique features that are not available with the Katana 700. These include calf rollers and an L-Track design that provides a deep tissue massage to target areas that other chairs might miss. Additionally, the model comes with a built-in music system that can help you relax while enjoying your massage experience. Unfortunately, Bluetooth connectivity is not available on this model. Therefore, if you are looking for a chair that will allow you to connect your device wirelessly to it, then the Katana 700 might be the better choice.

Inner Balance Wellness Jin 2.0

See Price

It is important to determine what your exact needs in a massage chair are in order to choose the right chair for you. There is no doubt that both the Inner Balance Jin 2.0 and the Osaki OS 4000T are two worthy choices.
Jin 2.0 has both lumbar and calf heating pads, while 4000T only has lumbar heat massage. The 4000T also has 46 total airbags, while the Jin 2.0 has 42. It features four rollers, has a compact design, is delivered fully assembled, and offers a relaxing experience. It has a large, easy-to-use controller with a variety of zero gravity positions.

OSAKI OS-4000T Massage Chair Notable Benefits & Features

Most people looking for home massage are attracted to this full body and foot massage chair because of its combination of high-end features, color options, and affordable price. The best-selling Osaki OS-4000T is now in its latest version, and the Osaki OS-4000T features new reflexology foot massage rollers and an improved airbag massage system that is much more durable.

Quad Style Roller

The enhanced massage experience is provided by the extra soft quad-style rollers in the Osaki OS-4000T massage chair, mimicking the feel of the human thumb. For better penetrating effects, the rollers can be adjusted to medium or narrow width according to individual needs. By dredging the main acupuncture points on the back, acanthus, forehead, and top of the head, the rolling manipulation clears collateral channels and dries them out.

Truly Ergonomic S-Track

With the Osaki OS-4000T Zero Gravity Massage Chair, your neck and back, especially the lumbar area, are supported by its ergonomic design following the natural S-curve of the spine. In this position, massage is more effective because it separates the discs of our spine individually and decompresses them, allowing nutrients to enter their tissues.

Lower Back Heat Therapy

The importance of heat in a massage experience has always been well known. As part of the lumbar area of the backrest of the Osaki OS-4000T massage chair, two large heat pads are placed so that gentle heat therapy can be applied to your lower back in an effort to loosen up those muscles that are often tight. As a result, your back massage will be more effective and you will experience much more relaxation.

Leg Scan & Extension

Using the zero-gravity button, you will recline into the first stage of zero gravity and the leg rest will expand to accommodate your legs better. It is an additional part of body scanning technology. This is ideal for taller users who can feel scrunched into the seat. When the leg rest reaches its maximum extension, it will retract again. Press your toes down on the footrest to stop the scan once you have found the position comfortable. By doing so, the airbags continue to massage the correct areas while your legs are comfortably seated within the leg rest.

Shoulder, Lumbar & Hip Massage

Designed to relax your shoulders, hips and lumbar areas, the Osaki Os-4000t massage chair has airbags in these areas. Additionally, these airbags are designed to work in tandem with the back massage rollers, so that you receive a much deeper massage of your back throughout the entire body. In the shoulder area, the shoulder airbags inflate and press your upper back on the backrest, so your back massage is a little deeper here. Similarly, your lower back is massaged from the hips and lumbar areas.

Large LCD Display Remote

Osaki OS-4000T’s remote control has a large backlit LCD display that gives you complete control over your massage. Select one of five pre-programmed massage routines, adjust a few settings and enjoy a personalized massage experience while you sit back and relax. When looking from the fully reclined position, you will be able to see exactly what is happening with your massage experience at any time. Moreover, this remote comes with a mini-remote so you don’t have to strain yourself to reach for the remote to control the chair’s basic functions.

Automatic Programs

A massage chair from Osaki features five automatic programs and three localized programs. There are five automatic programs: Muscle Relief, Thai, Stretching, Anti-Stress, and Demo. The three localized programs only target specific areas: Neck and Shoulders, Back and Lumbar, and Full Air.

Osaki Warranty

During the first three (3) years of ownership, Osaki guarantees that if you find your qualified product defective due to faulty parts, workmanship, or structural defects, they will replace it or repair it at their option, without charge to you. There is a one (1) year in-home labor warranty included with this plan as well as a three (3) year parts and structural framework warranty.

Other Osaki OS-4000T Modifications & Differences

OSAKI OS-4000XT

Osaki-OS-4000XT

With its LED light control system, the Osaki OS-4000XT massage chair provides an L-Track system with two steps of zero gravity, six automatic programs, and an Ache Sensor that detects the aching point of the user’s body when the arms are inserted naturally into the sensor. 

With the roller system, the neck is massaged first, then the lower back, glutes, and upper hamstrings are massaged. Multiple airbags are located throughout the massage chair to ensure a full-body massage experience. There are 24 airbags on the 4000XT massage chair.

Each airbag is located at the shoulder, arm, foot, and calf region. OS- 4000XT has one spinning reflexology massage roller located on the bottom of the feet, which provides a soothing kneading style application while increasing blood circulation throughout the body to relieve pain and tension. Acupressure points will be stimulated as the rollers spin, while airbags will generate a deeper massage along your feet’s bottoms as they inflate.

OSAKI OS-4000CS

Osaki-OS-4000CS

It offers space-saving technology, L-Track Massage, Adjustable Shoulders, and Zero Gravity to name just a few of the innovative features of the bestselling OS-4000 Series from Osaki. There is something unique about every chair in the OS-4000 series.

With its latest technology, the massage rollers map out the back’s curvature with great accuracy, resulting in a more effective massage and hitting all the right spots. This highly advanced chair will automatically adjust itself to accommodate any body type, so you will feel as though the massage is tailored specifically to your needs.

Some of the benefits of the Zero-Gravity feature:

  • Ease back pain almost immediately.
  • Increases and stimulates blood circulation.
  • Reduces swelling and minimizes stress.

Because massage chairs are reclined, they typically take up a lot of space. For a massage chair to fully recline, it takes up to 3 feet behind the backrest. Titan’s innovative design team has engineered a space-saving technology that slides the chair forward as it reclines. To maximize space savings, this chair can be positioned within 6 inches of a wall when fully reclined.

OSAKI OS-4000

Osaki-OS-4000

Among the most popular models in Osaki’s product line is the OS 4000 massage chair. With its wealth of features and luxury aesthetics, it’s not hard to see why. 

It has an S-Track with an ergonomic design. The first feature of the Osaki 4000 massage chair is that it has an ergonomic design with the S-Track system, which is designed to provide optimal comfort and contour to the spine.

Notable Features:

  • Upgraded PU covering for increase durability and comfort
  • 6 unique Pre-Set programs
  • Easy-to-use Large LCD display remote with wireless remote
  • Two Stage Zero-Gravity positioning
  • Foot, Calves, Arm, Hips, and Shoulder air pressure massage
  • Auto timer setting from 5-30 min. session
  • Five levels of speed and intensity for the massage
  • Seat Vibration Massage

Since spine curvatures vary from person to person, the S-track system provides the rollers with pressure and support without losing them along the way or at either end – a common problem with linear track systems.

As a result, every Osaki OS 4000 massage chair comes with the S-Track system. The Zero Gravity Two-Stage System. In any Osaki OS 4000 massage chair review, the zero gravity feature must be discussed since it is perhaps one of the most interesting and most misunderstood features.

OSAKI OS-4000LS

OS-4000LS

With an L-track style massage chair such as the Osaki OS-4000LS, rollers begin at your neck and wrap all the way down your spine, then wrap underneath your glutes, and then to the bottom of your thighs. Foot rollers and a spring-loaded ottoman have been added to the 4000Ls.

Also included are 24 airbag compression massages, body scan technology, zero gravity, and innovative adjustable shoulder massages. It is equipped with the latest technology to map out the back curvature with great accuracy, resulting in a more effective massage that hits all key areas of the back. You can enjoy a customized massage experience no matter what your body type is because this chair self-adjusts. Due to the fact that massage chairs are reclined, they take up more space.

For a massage chair to fully recline, it must be 3 feet behind the backrest. A space-saving technology developed by Titan’s design team slides the chair forward when it reclines, allowing it to be positioned within 6 inches of a wall. The L-Track system massages the neck, glutes, and back portion of the thighs from the neck to the glutes. The tracks in which the massage heads move are curved to contour the back and glutes.

What Do Users Say About OS-4000T Medical Massage Chair?


“My chair is amazing, I get 10 minutes of massage before work in the morning and 30 minutes of stress relief after work, so yes, I use it a lot, and I might wear it out before long. I wish there were more videos about how to use the chair.”
Leah

“It has been a pleasure to use this chair twice, since my daughter owns it and I have used hers a couple of times. Though we live close to each other, I plan to get my own chair soon. If you’re looking for a massage chair, I highly recommend this one to you. Just the thought of getting a full body massage anytime you like, in the privacy of your own home, is a wonderful feeling, so if you’re searching for one, I think this is the one to get.”
Jacky
