OS-4D Pro Maestro Massage Chair

Osaki has released the Osaki OS-Pro Maestro 4D Massage Chair, which has been in development for nearly two years. The Maestro is one of the most advanced massage chairs available today and is the only 4D L-Track chair in the world. With a 3D Point Navigation System and 4D technology, the Maestro rollers are heated so that speed variations are mimicked as closely as possible by a real massage therapist. Designed to provide a comprehensive massage experience, 4D chairs use heated rollers inspired by hot stone massages.

You’re in for a real treat with the new Osaki Pro-Maestro with 8 different 4D settings, 5 intensity settings, and 5-speed settings. It’s the most realistic Osaki massage chair yet. Using the newly engineered 4D roller system, the rollers provide a 3D massage with the speed variations of a real massage therapist while retaining the depth of a 3D massage. Thousands of massage therapists were studied to create this new experience, and Osaki’s engineering team developed a speed algorithm that was integrated into the Maestro robotic arm. As compared to conventional massage rollers, the Maestro massages a deeper, broader area in a rhythmical manner.

Human Touch Super NOVO

See Price

The OS-4D Maestro Massage Chair and Human Touch Novo Massage Chair are two great options for at-home massage treatments. While the OS-4D is more affordable, the Human Touch offers higher quality features such as the Altec Lansing Premium Sound System, S-Track and L-Track massage, dual lumbar heat, virtual therapist, body scan technology, and a total of 38 automatic programs.
The OS-4D has 5 levels of intensity, Zero Gravity, and 20 airbags with foot rollers and air compression for a more complete massage experience. The Human Touch Novo also offers dual lumbar heat and 36 airbags to ensure maximum comfort and relaxation.
Overall, both massage chairs offer great features and customization options, but the Human Touch Novo is a bit more expensive than the OS-4D Maestro. Ultimately it depends on your budget and needs to determine which chair will provide the best experience for you.

Osaki OS-4D Pro Maestro Massage Chair Notable Benefits & Features

SL-Track Technology

For an exceptional massage experience, the Osaki OS-Pro Maestro massage chair incorporates both S and L-Track technologies. For consistent massage pressure, the S-Track rollers contour to the natural curves of the spine. From your neck to your lower back, the L-Track wraps around the back of your thighs. Compared to your average S-Track chair, the L-Track offers about 50% more massage area.

Real 4D Massage

In comparison to conventional massage rollers, the Maestro offers a 4D L-Track massage that is wider, deeper, and more rhythmically massaged. It is the most human-like massage available. For the 4D massage and for Strength, Intensity, and Speed, Osaki OS-Pro Maestro has eight levels of adjustment.

Heated Rollers

There is no better back heating system on the market today than the Osaki OS-Pro Maestro. The roller itself heats up to simulate hot stones warming your muscles, so you can warm your neck all the way to the back of your thighs.

Double Sensing Body Scan

During the Osaki OS-Pro Maestro massage, a body scan is performed to map the key areas of the neck and back, as well as to detect your shoulders height. Once the scan is complete, the shoulders height can be re-calibrated.

Air Compression Massage

To provide a full-body massage experience, the massage chair comes equipped with 64 airbags. Compression massage helps to continue increasing blood circulation throughout the body to relieve pain and tension by supplying airbags to the shoulders, arms, waist, pelvis and calves.

Leg Scanning Ottoman

In order to determine the optimal leg length for your height, the ottoman will scan your legs. When the foot component is extended outwards, it retracts inwards. To indicate that the leg scanner has reached the desired length, simply apply your feet to it. Using the remote, a user can also adjust the leg component to either extend or retract according to their preferences.

What Do Users Say About Osaki OS-4D Pro Maestro Massage Chair?

“As a former owner of Inada Dreamwave, I can confidently say that this chair outperforms it. The massage on this chair is much better and stronger than Inada Dreamwave, and it has all those modern features that Inada Dreamwave is completely missing. It has SL tracking, Foot Roller, Bluetooth, built-in HD Speaker, android apps for remote control, true 4D heated roller, fancy lights and designs, etc. A massage chair that costs $9000 in 2018 must have at least these features, and the Inada Dreamwave had none. The chair gives amazingly good massages and is much more comfortable to sit in. It’s not as good as human hands, but it’s close.”
Nick A.

“A foot massager that is larger than a size 10-11 won’t fit comfortably in the foot massager. The 4D back functions are excellent. The foot massager is mediocre by comparison. I also hate a feature of the machine: every time you start a cycle, it will move the foot massager up until it senses heel pressure. It is incredibly annoying. Every time I start a cycle, I have to press my left heel down to stop the foot massager, and then I have to enter position mode to reset my leg length to maximum. I want the foot massager to stay where I set it, but it keeps doing this. The foot massager would be great if I could override that feature and have a bit more space.”
Jack F.

Frequently Asked Questions

Maximum Foot Size?

Maximum user foot size: US 12

Is Osaki made in China?

Final Thoughts

As part of Osaki’s 4D experience, you’ll get a range of settings, highly effective quad rollers, zero gravity, and an SL track that deliver all the benefits of a full body massage. Massage chairs are now equipped with Bluetooth Amphitheater speakers that offer superior sound quality.

If you want to take care of your health and enjoy at-home massages every day, Osaki OS-Pro Maestro is a great massage chair for you, but OHCO M.8 would be a better choice, but the price is slightly higher.
