Auto-Massage Programs

The Osaki OS-4D Pro Maestro LE has 8 automatic massage programs to choose from:


The Demo program does exactly what you’d expect: it demonstrates the basic massage options your chair has to offer.


The Relax program utilizes a softer massage to help your body loosen up into a more - you guessed it - relaxed state.


The Swing program massages you while rocking in a back and forth movement to create a more calming state throughout the massage. This is one of the most popular massage chair features today, and is the primary reason this particular model is a top seller at Sleep First.


The Stretch program takes you deeper. This program features a locking of the legs, hips, arms, shoulders using targeted airbags, followed by a slow reclining/declining experience to stretch and satisfy the muscles in your body. The Stretch function also helps to perform a lighter stretch for your calves, hamstrings, shoulders and waist.


The Scraping program helps to perform a popular scraping style massage. This technique involves starting at the inside of the body and moving towards the outside, helping to direct blood flow.


Shiatsu is widely favored and relied upon for a more pinpointed massage down the back. The Shiatsu massage style helps to focus on certain pressure points in your back, helping to relieve more stress and leave you feeling refreshed and rejuvenated. 


A program designed for those identifying as male which helps to stimulate blood flow. Works like a charm. 


The Rejuvenate program used stronger, deeper massage techniques, and is favored by people who enjoy sports massage or Thai massage. Rejuvenate is designed to increase blood flow and relaxation using stronger massage techniques than the rest of the massage chair’s settings. Don’t say we didn’t warn you!


6 Manual Massage Modes 

The Osaki OS-4D Pro Maestro LE Massage Chair comes with six (6) manual modes so you can pinpoint your massage to target specific areas on your back.
The Maestro can perform Kneading, Tapping, Shiatsu, and Rolling with 4 different modes per massage style.

You can choose to either pinpoint a specific spot on your back, or massage different sections of the body. Focus on your shoulders, arms, lower back or even tired calves you didn’t know were so tired. 

This massage chair offers custom settings for neck & shoulders, lower back, and everyone’s favorite - air massage.

Need more convincing? 

This OS-4D Pro Maestro LE has been upgraded and re-relased to offer two specialized massage style customizations. 

What does that mean? 

It means you can now combine two options: that’s right - two massage styles at the same time! Try ‘Kneading & Tapping’, or ‘Kneading & Shiatsu’, for example.
The Osaki OS-4D Pro Maestro LE offers a combination of manual massage styles for better massage techniques. Find your favorite combo while you watch the morning news! 

Learn The Technology

L & S Track Technology

The Osaki OS-4D Pro Maestro LE combines both S and L track technology for an exceptional massage experience.
S-Track rollers contour the natural curvature of your spine. 

L-Track rollers extend from your neck, running all the way down your lower back, and finally wrapping under the back of your glorious thighs.
L-Track offers about 50% more massage area than your average S-Track chair. You’ll be experiencing both with this Osaki chair. 

Heated Back Roller Massage

The Osaki OS-4D Pro Maestro LE has the most advanced back heating system with a mild infrared heat. The roller itself will heat up at the same time as you do. Heated back rolling allows for a far greater surface heating area, so you can mimic the luxury of hot stones warming the muscles from your neck to your hamstrings. Indulge as often as you’d like!

Body Scan Technology

The OS-4D Pro Maestro LE will perform a body scan to map the key areas of your neck and back to ensure the optimal amount of pressure is applied during your massage. The scanning technology will detect your shoulder height (which can easily be re-calibrated once the scan is complete).

Auto Leg Scan & Leg Extend

You chair’s intuitive ottoman will scan your legs to ensure the optimal leg extension is paired with your height. To accomplish this, the foot will extend outwards and then retract inwards slowly until it reaches your tootsies. Simply apply pressure with your feet to indicate to the leg scanner that you’ve reached your desired position. An easy to use remote also allows you to auto adjust the leg component to either extend or retract to the user’s personal needs.

Full Body Air Massage

Airbags provide a totally unique full-body massage experience, and this amazing massage chair offers a total of 32 airbags! Reach every nook & cranny with firm, responsive air pressure technology.
In case you want to count ‘em, the 32 airbags are located at the shoulders, arms, waist and pelvis, and calf areas. This deep compression massage relieves pain and tension.

Foot & Calf Kneading

Do your feet need a treat? You’ll be delighted to find there are spinning reflexology rollers located under your feet that will provide you with an outstanding massage.
The rollers start under your feet, traveling along the sides and middle of your feet to imitate a hand-kneading experience. The calf area airbags will inflate to the appropriate amount of pressure, initiating a calf kneading massage. 

Calf, Bridge, Knee & Heel Massage (all-new features on this model!)

Air massagers on the upper leg rotate in a circular motion to add a whole new dimension to your calf massage. A new component has also been added to stretch and massage the bridges and heels of your feet. This upgraded experience is truly like no other!

Zero Gravity

Arguably the most recognized feature in a massage chair, Zero Gravity is the perfect position for ultimate relaxation. Inspired by NASA, when placed in Zero Gravity position, the weight of your back will be virtually supported by the backrest. In this position when the knees are brought above the chest will optimize your blood flow, in order to relax the body more. This will in turn help to maximize the intensity of the massage and reduces the compression along your spine.

Space Saving Design

The Osaki OS-4D Pro Maestro LE massage chair only needs 5” from the backrest to the wall. This convenient design allows you to fully maximize your living space.

Bluetooth & HD Speaker

The Osaki OS-4D Pro Maestro LE massage chair is equipped with Bluetooth technology and an Amphitheater sound system that reduces the surrounding noise, enhancing your listening experience. This modern technology allows you to listen to your favorite music on Osaki’s highest grade of audio speakers located in the headrest. It is advised to activate the Bluetooth speakers at the lowest volume before playing music, and then gradually increasing to a desired level. A blue light on the speakers indicates you are are synced with your device.

Re-Modeled Touch Screen Remote Tablet

The Osaki OS-4D Pro Maestro LE’s remote has been upgraded to a Touch Screen Remote Tablet. This luxury remote has a larger screen to make managing your massage as easy as pie. This easy viewing screen displays active functions and customization options in a convenient location. A smart magnetic holder keeps your remote firm in place. The remote allows you to select your massage type, intensity, speed, and body location. You can also operate each function independently by using Manual Mode.

Quick Controls

The inner armrest gives you quick access to the most frequently used buttons: Power, Play/Pause, Auto, Zero Gravity, and 4D. 

You can even charge your device using the USB outlet provided. Such a handy little extra feature!

Wireless Charger (this is so cool)

The OS-4D Pro Maestro LE massage chair also includes a new wireless charging option. Now you can charge your smartphone wirelessly using the new wireless charging pad located on the hand area. 

iPhone & Android Apps

iPhone & Android users or tablet users can use Osaki’s special App to operate this massage chair. The full selection of remote features are available on the App. Instructions for downloading the App are included in your shipment.

    Best feeling

    Amazing chair,before purchasing I tried so many different chairs,nothing is close for the feeling of the Osaki 4d

    Tony T.

    The Pro Maestro is by far the best of the best. Completely adjustable, massages more of the body than any other chair. I heard this chair was coming, researched it heavily, read the reviews once the chair was has exceeded my very high expectations. If you want the best, buy this chair.

    I wish I would have bought this 10 years ago! I love, love, love this massage chair! I was nervous to buy such an expensive item without trying it out first but It is better than I expected! It was easy to put together with the help of another person. The zero gravity, foot massage and lower back are exceptional. I like the arm massage feature however I would add more airbags to the arms if I had the option. It is easy to operate, I haven't figured the custom settings out yet but I like the auto massage so much I haven't really looked at the custom massages yet. It is so relaxing and has helped increase my quality of life.
