Osaki OS-4000CS Massage Chair Review

osaki os-4000cs massage chair review

The Osaki OS-4000CS massage chair is the next iteration of the all-time best selling Osaki OS-4000T. A host of new improvements and upgraded features to address issues people had with the previous model, and to provide a much better massage experience. The good thing about this chair is the union of S and L-Tracks, which can both attend to the changing curves of your spine and extend its reach to your hamstrings.

Massage Track

The Osaki OS-4000CS uses an L-track massage system that has an extra-long massage track. Your massage will now go from your neck to your upper thighs. This massage track style offers all of the same benefits as the S-shaped massage track, including consistent pressure throughout your back massage and adds the extra surface area, as well as better support for your lumbar and neck areas.

Space-Saving Technology

Space-saving technology is an often sought-after feature in modern massage chairs. Where several massage chairs might need up to 12 inches behind the chair to fully recline, the Osaki OS-4000CS only requires four inches. Through clever use of a track built into the base of the massage chair, it can slide forward as its reclining to save a great deal of space behind this anti-gravity massage chair. If space in your home or office comes at a premium, this massage chair is for you.

Zero Gravity

Zero gravity positioning has become a staple in modern massage chairs due to its healthful benefits to your massage and its improvement of your massage experience. As you recline into the zero gravity position your legs are raised to the level of your heart so that your body weight is no longer compressing your joints. This helps your entire body relax and allows you to receive a much deeper benefit from your massage.

Adjustable Width Shoulder Massage

An innovation with the Osaki OS-4000CS is the adjustable shoulder massage. This feature is designed to address one of the most common complaints of the older OS-4000T from users with broad shoulders. The shoulder massage was a bit cramped and frequently made them feel uncomfortable and constrained. With this shoulder adjustment feature, no matter how broad or narrow your shoulders are you can sit comfortably in the chair and receive a shoulder massage that suits your unique size and needs.

Airbag System

The Osaki OS-4000CS massage chair uses 24 airbags to provide a full-body compression massage to complement your back massage. With a lower number of airbags covering the same surface area, the massage chair is more durable since there are fewer valves involved. With fewer valves, the airbag system puts less stress on the chair and uses far less power. 

Airbags in the adjustable shoulder and armrest provide a compression massage to your shoulders, forearms, and hands. This helps promote circulation and relief throughout your upper body. Waist airbags inflate to push your lower back into the backrest to improve the intensity of your lower back massage. These airbags also provide a squeeze to your core that helps hold you in place during the stretch modes. 

The leg rest is outfitted with airbags to apply a compression massage to your legs and feet. In the footrest, the airbags press your feet down on a plate with nodules designed to stimulate acupoints throughout your feet to provide relief to your feet and throughout your body.
