Features Of Osaki OS-4000XT Massage Chair

L-Track Massage

One of the most impressive and upgraded features of the Osaki OS-4000XT massage chair is the L-Track massage system. With a set of rollers, it follows the natural curve of your spine and extends from your neck to your hamstrings.

This ingenious technology provides a deep and comprehensive full-body massage experience that covers your entire back area, even the lower back, and reaches your glutes and thighs. Besides, the massage chair holds a decent tension sensor, too that detects the aching points of your body and adjusts the massage intensity accordingly.

Full-body Airbag Massage

Another feature that makes the Osaki OS-4000XT massage chair stand out, and most users love is the state-of-the-art, full-body air-bag massage system.

They are 32 in number and function collectively to cover your arms, shoulders, calves, and the whole body from head to toe. As a result, it increases blood circulation and relieves pain and tension.

Six Auto Massage Programs

With six different auto massage programs that you can choose from, and in fact, each program is designed to pinpoint a desired massage for a specific area, the OS-4000XT Massage Chair caters to almost any need and preference.

From Recovery, Relaxation, Wakame, Shiatsu, Thai, and Stretching massage programs. Apart from auto programs, the massage chair also lets you set the intensity of the massage, which particularly makes the chair a great fit for people with different pain thresholds.

All in all,  the auto massage programs are pretty easy to select using the remote control and you can also pause or resume the massage at any time.

Six Massage Styles

The versatility of the Osaki Os-4000XT massage chair is epitomized by its six configurable massage styles. With options to customize your massage, you can enjoy any style that suits your mood, from kneading to tapping.

I found that the OS-4000XT can perform kneading exceptionally well, and provide a deep, therapeutic effect that soothes even the most stubborn muscle knots.

Two-Step Zero Gravity Mode

Osaki OS-4000XT - Two-Step Zero Gravity Mode

The massage chair moves to a position where your knees are slightly above your heart and optimizes your breathing and increases overall blood flow.  When you recline this massage chair into any of the 2-step zero gravity positions, it reduces the pressure on your spine and joints and enhances the massage effect.

Honestly, it feels like I’m floating. the first step zero-gravity is similar to the feeling of lying down on a flat surface, but the 2nd step further reclines you in a more horizontal position to correct your wrong and bend posture and let you breathe more comfortably and deeply.

Space Saving Technology

OS-4000XT - Space Saving Technology

Despite its numerous features, the OS-4000XT has been engineered with a space-saving technology that slides the chair forward as the chair reclines.

This feature is especially useful for those with limited living space, as it can be easily positioned only two inches from the wall, saving you valuable floor space.

Easy-to-Use LCD Remote

OS-4000XT - LCD Remote

The OS-4000XT comes with a user-friendly LCD remote that displays the chair functions and settings.

The remote response rate is pretty much fast, and it lets you select the auto massage programs, the massage styles, the intensity, the speed, the width, the position, the heat, the zero gravity, the Bluetooth, and the timer.

The remote control also shows you the current status of the massage, the remaining time, and the battery level.

Built-in Bluetooth Speakers

Osaki OS-4000XT - Bluetooth Technology

Bluetooth technology is the most decent feature and basically an upgraded feature of the Osaki OS 4000XT massage chair that sets it apart from its older 4000T version.

With Bluetooth availability, you can easily connect your daily use smartphone or tablet and listen to your most favorite music or audio while getting a massage.

It feels so soothing while reading so imagine how you feel during a massage. It’s simply AMAZING!

Extendable Footrest

OS-4000XT - Extendable Legs

The Osaki OS 4000XT massage chair easily caters to a person of height between 5 feet and 6 feet 3 inches. And beyond this, the footrest extends up to 6.5 inches for maximum comfort.
