The OS 4000CS massage chair has adjustable outer shoulders. The outer massage airbags are moveable to adjust according to the height and width of the user. Most massage chairs in the market have no ability to adjust the shoulder position and they are ineffective. However, the OS 4000CS massage chair has the ability to adjust shoulders to 3 different widths.  The user can improve the strength and fitting of the outer shoulder massage.​

The OS 4000CS massage chair gives ​Ergonomic Arm Massage as the position of the arm massage places the palms of the user in towards the body with protective covers to reduce dirt build-up from the spandex material. Along both sidewalls of the seat, airbags inflate and release for hip & thigh massage.

Most massage chairs occupy more space during the recline position. Usually, massage chairs require up to 2-3 feet behind the backrest for the chair to fully recline. However, this Osaki model is space-saving. During fully reclined this chair gets only 6 inches space from the wall.
