Osaki OS-4000LS Massage Chair

The Osaki OS-4000LS Massage chair provides an incredible massage from your neck all the way down to your upper thighs thanks to the L-track massage system that extends the massage track below your lower back. Combine this extra massage surface with the adjustable shoulder massage, zero gravity, heat therapy and new foot massage rollers and you have an incredible massage experience for much less money! Learn more about this chair below and see what it can do for you.



L-Track Massage System

The L-track massage system is an important innovation that extends the surface area that your back massage covers down passed your lower back, through your glutes all the way to your upper thighs. This increases the total surface area of your back massage by about 30% which provides more relief and more value for your investment.


Zero Gravity

The Osaki OS-4000LS massage chair offers zero gravity positioning at the push of a button. As you recline into this position your legs are raised to the level of your heart in an effort to remove the pressure of gravity from your joints and spine. This allows your joints and muscles to decompress and relax which deepens the overall effect you receive from your massage chair.


Foot Massage Rollers

New foot massage rollers have been places in the foot rest. These massage rollers apply a kneading style massage to the soles of your feet which is a great feature to enjoy after a long day at work. Using the remote you can easily turn this feature on or off to suit your personal preference.


Adjustable Shoulder Massages

The shoulder massagers within the Osaki OS-4000LS massage chair have three levels of adjustment. This ensures that the shoulder massage is incredibly comfortable no matter how tall you are, or how broad your shoulders. Simply push the shoulder massager in until you hear a click for the next setting, of if you want to go out, push it all the way in and pull it out until it stops.


Lumbar Heat Therapy

The lumbar of the backrest features two heating pads that help loosen up the large muscles groups throughout your lower back and lumbar. This helps soothe away tension and allows you to receive a much deeper benefit from your massage experience.


Space Saving Technology

The Osaki OS-4000LS massage chair is a space saving massage chair. Many massage chair can require a significant amount of room behind the chair to fully recline, so you are forced to place your chair anywhere up to 2-3 feet away from the wall so you don't have to worry about scratches on your chair or the wall. This massage chair only requires about 4" behind the chair to fully recline thanks to this technology. As the chair reclines the base slides forward to minimize the necessary space behind the chair.


Spring Loaded Ottoman Extension

The Osaki OS-4000LS ottoman includes a spring loaded feature that keeps the footrest pressed against your feet. If you want to extend the legrest simply press your feet out until your legs are comfortable and the spring will keep the footrest comfortably close to your feet so that your foot massage doesn't lose pressure.


Body Scan Technology

Just like all Osaki Massage chairs, when you start a massage program within this massage chair the massage rollers will glide up your back in an effort to map your unique size and shape, as well as the height of your shoulders so your massage routine can be catered to the unique shape of your body. This feature makes every massage session feel comfortable and personalized.


Vibration Massage

Within the seat are two vibration plates that provide a gentle vibration massage to your hips and lower back. This vibration reverberates through the muscles all the way down to the surface of the bone. This helps loosen up tension throughout your lower back so that your back massage is much more effective in this area.


Easy to Use Remote

The remote for the Osaki OS-4000LS massage chair has been redesigned and condensed to provide an easy to hold, and easy to use design that makes choosing your massage program and making any necessary adjustments quick and easy.


6 Automatic Programs

  • Deep Tissue - Perfect for those deep knots. This routine focuses on massaging deep into your muscle tissue for much deeper long-lasting relief.
  • Relax Mode - Designed to help you unwind, this routine focuses on melting away stress and helping you find relaxation.
  • Full Air - This mode uses the airbags only to provide you with a full body massage experience.

  • Manual Air - With this mode you can turn on specific airbags so you only massage the areas you want.
  • Dual Action - This is a full body massage experience that adds a swing in the seat of the chair to help loosen up hip muscles.


Full Body Air Ccompression

24 Airbags have been placed throughout the massage chair in the shoulders, arms, hips, seat, legs, and feet to provide a compression massage to your body. This also helps provide a stretch massage within some of the massage programs that helps to provide you relief in areas that the massage roller can't reach. Airbags are located in the shoulders, seat, legs, feet, arms and wrists. The six massage programs include deep tissue, relax, full air, energy stretch, manual and dual action. Finally, the four techniques are kneading, tapping, shiatsu and rolling.
