Osaki OS-4000CS Massage Chair


​​The Osaki OS-4000CS Massage Chair is part of the bestselling OS-4000 Series, offering an array of innovative features like space saving technology, L-Track Massage, Adjustable Shoulders and Zero Gravity. Each chair in the OS-4000 series has something unique to offer.





The L-Track system massages from the neck, past the glutes, and down to the back portion of the thighs. The track in which the massage heads move are curved to contour the back and glutes area.


Many massage chairs require up to 2 feet behind the backrest for the chair to fully recline. The Osaki OS-4000CS Massage Chair features space saving technology that slides the chair forward as the chair reclines. Fully reclined this chair can be positioned within 4 inches of a wall for maximum space saving.​



On each side of the lower lumbar area there are individual heating pads. The heat therapy is a great compliment to the roller and airbag massage. Heating the body’s temperature is known to increase blood circulation and loosen tense muscles. The heating pad is not intended to exceed more than 30 minutes of usage a day.


The Osaki OS-4000CS Massage Chair will scan your back and adjust to create a more accurate massage to your specific body type.


Inspired by NASA, the Zero gravity position is a great way to enjoy a massage. It positions the spine so that it reduces the vertical pressure. In the Zero Gravity position, the weight of your back is virtually supported by the backrest which helps maximizes the intensity of the massage. 


Osaki has been engineering its chairs to reduce the airbag count and at the same time increasing the surface area by using more pliable and durable material which have received great feedback. All 24 airbags are strategically placed to optimize the squeezing effect of the
