In this massage chair review, we will look more closely at its key characteristics. We'll also cover the chair's benefits and drawbacks, address some frequently asked questions, and present customer feedback. Here we go!

Main Distinguishing Features

The developers of the Osaki OS-4D Pro Maestro LE Massage Chair sets the chair apart from others by packing it with unique features. With this luxurious massage chair, you can enjoy the following main qualities:

Superior 4D Massage

This 3D/4D massage chair boasts a 4D massage system that allows for more precise control over the massage rollers. In this way, you'll enjoy a more personalized massage experience. Additionally, it boasts 5 adjustments for strength and 8 degrees of adjustment for the 4D massage. Thus, the Osaki OS-4D Pro Maestro LE Massage Chair is made to apply pressure to a deeper, larger area more rhythmically.

52" S+L Track Technology

The Osaki Pro Maestro LE combines the accuracy of an S-Track that flawlessly mimics the arc of your spine. Likewise, the massage rollers follow an extended L-track that covers your neck, back, glutes, and hamstrings for a full-body massage.

Heated Back Roller Massage

An extremely sophisticated heated roller that simultaneously massages the neck and hamstrings is a characteristic of the Osaki OS-Pro Maestro LE. The heated rollers provide a soothing and relaxing massage experience. Ultimately, helping to relieve muscle tension and improve circulation.

Body Scan Technology

The OS-Pro Maestro LE will perform a comprehensive body scan, customizing the therapeutic session to your body. This will guarantee that the appropriate amount of pressure is applied throughout the massage. Likewise, it can precisely map the critical areas of the neck, shoulders, and spine.  Furthermore, the chair scans your body before each massage session to customize the massage to your unique body shape and size.

Zero Gravity

The Zero Gravity position, developed by NASA, is ideal for complete relaxation. Raising the legs so that they are in line with the heart relieves the spine of all pressure. Certainly, you will enjoy the feeling of being almost weightless.

Full Body Air Massage

The Osaki Pro Maestro LE has 30 airbags distributed throughout it to provide a full body massage. While reducing pain and stress, the rolling and light compression techniques also help to keep you steady while receiving the massage. Your arms, hips, and shoulders will all receive a full-body massage from the chair's airbags.

Foot & Calf Kneading

Under the feet of the  Osaki OS-4D Pro Maestro LE Massage Chair, there are rotating reflexology rollers that offer superb foot massage. Notably, the rollers in the foot and calf area provide a deep tissue massage to help alleviate tension and soreness. The calf airbags will inflate to start a calf kneading massage together with the foot rollers. 

Auto Leg Scan & Leg Extend

The Osaki Pro Maestro LE ottoman analyzes your legs to make sure they are the ideal length for your height. To accommodate your feet, the footrest will first extend forth and then retract inward. Simply, press down with your feet to signal to the leg scanner that you are in the appropriate posture. You can automatically modify the leg component using the remote as well.

Bluetooth & HD Speaker

The Osaki OS-Pro Maestro LE has Bluetooth capabilities and an Amphitheater sound system. Such advanced functions lessen outside noise and improve listening quality. The best audio speakers available from Osaki, which are housed in the headrest, enable you to enjoy your favorite music. If the speakers have synchronized with your smartphone, a blue light will appear on them.

Space Saving Design

The  Osaki OS-4D Pro Maestro LE Massage Chair requires less room than other chairs since the distance from the backrest to the wall is only 3". The massage chair slides forward when you relax, maximizing your living space.

New Remodeled Touch Screen Remote Table

Osaki has modified the remote control for the OS-4D Pro Maestro LE to a touchscreen tablet. To ease the user's operation of the massage chair, the manufacturer has improved the remote control to a larger screen. It features an easy-to-view screen that shows the function that the chair has selected. Additionally, it contains a magnetic holder that secures the remote. You can choose the massage style, intensity, speed, and location via the remote. In the Manual Mode, the features can also be used individually.

The Osaki OS-4D Pro Maestro LE massage chair's engineering team paid close attention to every last detail. In this way, they created the most ergonomic and user-friendly chair imaginable. Everything is easily accessible thanks to simple controls and a USB charger, including the battery life of your phone.

Wireless Charger

Frequently Asked Questions

If you're considering purchasing the Osaki OS-4D Pro Maestro LE Massage Chair, you likely have questions about its features, assembly, and maintenance. Need help in making an informed choice? Then, let's address some of the most common questions about this massage chair.

Q: What kind of warranty does this come with?

A: Titan Osaki's free extended warranty is included with the Osaki OS-4D Pro Maestro LE Massage Chair. This includes 3 years of in-home parts/labor/service. As well as, 2 additional years of parts for a total of 5 years of coverage.

Q: What is the assembly like?

A: The Osaki OS-4D Pro Maestro LE Massage Chair requires some assembly, but it comes with a clear instruction manual and all the necessary tools. The set-up can be completed fast if you are skilled at putting furniture together. You’ll first unbox the chair and begin by taking out the main body.  Next, you will attach the side panels. It’s helpful to have 2 people for this part of the job. One person can connect the air and electricity while the other holds the panel in place for the attachments and bolting.
