If you're weighing the options between the Inner Balance Ji massage chair and the Osaki OS 4000T massage chair, there are some key points that will help you decide which one is the right option for you.

By the end of this article, you'll have a good idea which of these popular massage chairs is the best choice for you.

Inner Balance Ji: Top Features

Full-Body Massage

This is a chair that's great for those looking for a full-body massage. Sometimes, the pain and tension seem to be coming from everywhere, not isolated to one or two places on the body. If this is how you often find yourself feeling at the end of a long day, you'll love coming home to a Ji by Inner Balance.

Zero Gravity

The Ji features a design that's perfect for achieving the zero gravity position, which experts agree to be the most comfortable and relaxing way to enjoy a massage. While it may sound like something out of science fiction, the zero gravity position merely involves positioning the user's knees above their heart.

This might seem simple enough, but the effect is a powerful feeling of feeling almost weightless.

Heat Therapy

For some types of muscular pain, heat seems to be the only thing that provides any relief. This chair comes equipped with a soothing heat therapy function that focuses on the lumbar area and calves.


The Ji has a track where the upper portion is shaped like an S to help conform to the natural shape of your spine, and the lower portion of the track (the L-shaped portion) extends out to the back of your thighs.

Advance Body Scan Technology

The advanced body-scan technology is able to identify the most prominent acupuncture points on your body. This allows the rollers to modify their motion to suit your height and build precisely.

This is thanks to the Quad Style Roller Technology paired with the body scan feature. There are two quad style rollers on either side that accurately imitate the massage style of a real human hand.

LCD Remote

The features of this chair are controlled using an LCD remote that's slim and fits easily in your hand. It's easy to operate, and the LCD screen shows you everything that the chair is currently doing during your massage.

Users can quickly find which program they are looking for and get the massage experience they want without a big technological struggle.

Foot Rollers

The Ji's foot rollers use reflexology techniques to deliver a targeted foot massage. The rollers knead the bottom of the feet, complemented by air compression that gently shifts the feet side to side.

This increases the rollers' coverage of the various acupressure points on the feet. Through this use of reflexology, tension is released throughout the entire body.

Osaki OS 4000T: Top Features

Computer Body Scanning

The 4000T comes with Computer Body Scanning, which helps the rollers precisely map out the user's back. The massage rollers begin at the back of the neck and extend down to the lower back area. You can adjust the rollers' speed and intensity to fine-tune your massage experience.

Zero Gravity Positions

The 4000T offers two zero gravity positions for you to take advantage of.

The second position is even more reclined than the first and will make the rollers feel more intense.

46 Airbags

With the Osaki chair's forty-six airbags, it's able to deliver the perfect massage to just about every part of the body, including the arms. Users can adjust the intensity to their liking.

A process of inflating and deflating allows the airbags to provide users with a squeeze in the lumbar, hips, and shoulders which allows for a whole new level of relaxation from the shoulders to the thighs. There are also two heating pads located in the lumbar area, which helps loosen stiff muscles.

There is a vibration plate located in the seat's base that provides a soothing vibration massage to the user. These vibrations loosen up the muscles in the back of the thighs in ways that other types of massages can't.

Foot Massage

For the feet, there are two rows of rollers to give users a deep, targeted, kneading massage. The addition of the airbags on both sides keeps the feet locked into place to allow the rollers to work as effectively as possible. The foot massage focuses on stimulating acupuncture points, using reflexology to create a general state of well-being.

There are airbags located on the back and sides of your feet and legs, which all help to provide a thorough calf massage. The compression massage that users receive from these airbags not only feels great, it can also help increase blood flow.

Automatic Leg Scan

With an automatic leg scan, the Osaki OS 4000T optimizes itself for your leg length. The chair fully extends at the start of the massage, then begins retracting. You get to tell the chair when the length is perfect simply by pressing your toes firmly into the bottom.

Full-Size Controller

The full-size controller is easy for anyone to navigate. You can adjust your massage experience or even change to a different massage style entirely.

Additionally, there's a compact wireless controller that gives you the ability to make adjustments without having to lean or reach for the main controller.
