  • Lumbar Heat Therapy
  • Zero Gravity Position

New from Osaki, the Osaki OS-4000CS is a new high-end upgrade to the best-selling massage chair the Osaki OS-4000T.

Osaki 4000CS Massage Chair Features


L-Track Massage System

The massage track of the Osaki OS-4000CS is 42" which comfortably reaches from neck to upper thigh on most users. The L-track massage system increases the overall surface area of your back massage and provides much better support in the neck, and lower back areas so you can sit more comfortably and relax a little more deeply. The L-track system provides all the same benefits of an S-track massage system, including a uniform massage across your entire back, and improves your overall back health by allowing the massage rollers access to each vertebra individually.


Space-Saving Technology

Space-saving technology is something that is very much sought after in massage chairs. Where many massage chairs can require up to 2.5' behind the chair to fully recline, the Osaki OS-4000CS requires 4". Through clever use of a track built into the base of the massage chair, the OS-4000CS can slide forward as its reclining to greatly save on space behind this anti-gravity massage chair. If space in your home or office comes at a premium, this massage chair is for you.


Lumbar Heat Therapy

Heat is an important part of any massage experience. Located in the lumbar area of the backrest are two heating pads that apply gentle heat therapy to your lower back. This feature goes a long way to help soothe lower back pain and loosen up tense muscles throughout your back.


Zero Gravity Position

The Osaki OS-4000CS provides zero gravity capability to improve your massage experience. The zero gravity position was introduced by NASA a few decades ago as a way to reduce stress on astronauts during their flight missions. This position reclines you back and raises your legs above your upper body which releases your joints and spine from gravity's influence. This release helps your joints and the surrounding muscles decompress which can cause a feeling of weightlessness throughout your body. Another benefit on top of your joints and muscles relaxing is that the majority of your body weight is focused on the backrest which helps to improve the intensity of your back massage without the massage chair having to work any harder.


Adjustable Width Shoulder Massage

A new innovation with the Osaki OS-4000CS is the Adjustable shoulder massage. This feature is designed to address one of the most common complaints in the OS-4000T from users with broad shoulders. The shoulder massage was a bit cramped and often made them feel constricted and uncomfortable. With this shoulder adjustment feature, no matter how broad or narrow your shoulders are you can sit comfortably and get a shoulder massage that suits your size and personal preferences.


6 Automatic Programs

There are 6 automatic programs to choose from that combine all fo the different massage styles in unique ways to provide relief throughout your body. This includes a unique hip swing feature that will help loosen up your lower back muscles. The Osaki OS-4000CS includes 4 of the most popular massage styles as well as the ability to combine them to bring your manual massage experience to an all-new level. These massage styles are Kneading, Tapping, Shiatsu, Rolling.


Full-Body Airbag System

Like most massage chairs, the Osaki OS-4000CS is outfitted with a full-body airbag system that provides a comfortable compression massage throughout your body. The difference in the OS-4000CS is that it only uses 24 airbags to cover the same amount of surface area as previous versions. A lower number of airbags means that there are fewer valves, and lower stress on the chair every time one inflates. This causes the anti-gravity massage chair to consume less power and makes it more durable.


Shoulder & Arm Airbag Massage

The Osaki OS-4000CS massage chair offers airbags in the shoulders and armrest to apply a compression massage that helps promote circulation through your arms and hands. The airbags in the shoulders squeeze your shoulders together and press you back on the backrest to improve your back massage.


Waist Airbag Massage

Airbags in the hip and waist area inflate to squeeze the hip area while pressing your lower back in the backrest to improve your lower back massage. These airbags are also very useful in any twisting and stretching programs.


Legs & Foot Airbag Massage

The Osaki OS-4000CS massage chair offers airbags in the legs and feet to promote circulation throughout the lower half of your body and to apply a squeezing massage to your feet that presses your feet down on nodules in the footrest to help stimulate acupoints throughout your foot.


Spring-Loaded Footrest Extension

The footrest in the Osaki OS-4000CS is easily extendable to accommodate taller users with longer legs. Simply press your feet down on the bottom of the leg rest and relax when it is at a comfortable extension. The spring action ensures your foot massage stays uniform no matter how far the ottoman is extended.


Body Scanning technology

When you sit down and turn on this massage chair, the massage rollers glide up your back to map your unique curves and the height of your shoulders. This ensures that no matter what massage routine you have chosen, it will feel personalized to you.
