Osaki OS-4000CS Massage Chair

The Osaki OS-4000CS massage chair is the newest upgrade to the best selling Osaki OS-4000T massage chair. The new design combines some of the latest features and technology to create a truly incredible massage experience. The new OS-4000CS is available in 3 colors and has a significant instant discount listed above!

L-Track Massage System

The Osaki OS-4000CS massage chair has been upgraded to the L-track massage system. This massage track is very long and reaches well below your hips all the way down to your upper thighs. This increases the surface area covered by your back massage by about 33% which means you get 33% more benefit from the primary use of your massage chair.

Space Saving Technology

Most massage chairs require anywhere from 12-30" behind the chair to fully recline. With space saving technology the Osaki OS-4000CS massage chair you only need 4-6" (6 recommended) behind the chair to fully recline. This is possible thanks to the track that the base of the massage chair is on. As the chair reclines, the base slides forward to minimize the necessary space behind the chair. This ensures that you can have this massage chair much closer to the wall than most massage chairs and still fully recline.

Lumbar Heat Therapy

Heating elements are included in the lumbar area of the backrest. These provide a relaxing heat therapy to your lower back which can help loosen up tense muscles and make your overall massage experience more pleasant and more effective.

Zero Gravity Position

The Osaki OS-4000CS massage chair features zero gravity positioning which is designed to improve your overall massage by helping muscles across your body relax and your joints decompress. As your legs are raised to the level of your heart, your joints and spine relax which helps loosen up the muscles throughout your body. This can cause a sort of weightless feeling in some users, but overall this helps your entire massage become even more effective.

Adjustable Width Shoulder Massage

One of the primary complaints about the Osaki OS-4000T was the fact that the shoulder massagers in larger users were very snug to the point of being constricting. To combat this the Osaki OS-4000CS massage chair has been outfitted with adjustable shoulder massagers that cater to very broad shoulders and can be personalized to fit widths of varying sizes.

Intuitive Remote

The remote for this massage chair has been simplified to provide quick and easy access to all of the important features of the massage chair. Choose your favorite of the 6 massage programs, make your adjustments and enjoy your massage.

Full Body Airbag System - 24 Airbags

24 airbags have been placed throughout the massage chair to provide a compression massage throughout your body and to complement the back massage. Airbags in the shoulders and hip area press you back on the backrest so the massage rollers can massage a little deeper into the muscles. The airbag system allows the Osaki OS-4000CS to provide a full body massage experience with fewer airbags and much less stress on the chair.

6 Massage Programs

There are 6 automatic massage programs that provide relief to your body in very different ways. These massage programs include:

  • Deep Tissue - This programs digs deep into your muscle tissue to provide maximum relief and relaxation.
  • Relax Mode - Relax mode helps you relieve stress and tension throughout your body with a gentle yet relaxing massage.
  • Full Air - This mode uses the 24 airbags to apply a compression massage throughout your body to improve circulation.
  • Energy Stretch - This program uses a combination of positioning and the airbags to stretch out and invigorate your body.
  • Manual Air - Turn specific airbags on and off to help guide the massage chair to areas you need to be massaged more.
  • Dual Action - Dual Action provides a full body massage and incorporates a chair swing motion.

4 Massage Techniques

The Osaki OS-4000CS massage chair offers four massage techniques that it uses within its automatic programs. These include kneading, tapping, Shiatsu, and rolling.

Spring-Loaded Footrest Extension

The leg rest provides an easy extension for taller users. Simply press down with your feet and the spring-loaded extension will keep the footrest close and at a comfortable distance. This also ensures that all of the airbags in the leg rest massage the correct places.

Body Scanning Technology

The Osaki OS-4000CS massage chair scans your back at the beginning of each massage session so it knows exactly where you are in the chair and how tall your shoulders are. This helps your massage experience feel personalized as it keeps the massage rollers on your back rather than guessing through a routine.

Vibration Massage

Vibration plates within the seat provide a vibration massage to your lower back that reverberates up your spine. This type of massage can do wonders for lower back pain, by loosening up muscles so they get a much deeper benefit from the back massager.
