  • L & S Track Massage System: You have the L track style of massage on the Osaki OS 4000 CS massage chair. This means that the rollers will go all the way from the back of the head under the seat and then back up again and so you get a medium to deep massage right from the neck. The Osaki 4000 massage chair is also ergonomically designed with an S-Track system to provide optimal comfort and an outline of the spine. The S-Track system is found on all models in the 4000 series.

  • Lumbar Heat Therapy: There are some lumbar airbags as well in this massage chair. They re-engineered the air compression chambers so that you will get full-body air compression. Even though there are only 24 airbags, this chair features six different automatic programs; you have deep tissue relax, stretch energy full air manual air, and then the energy massage, which is the most vigorous.
  • Air Bags:  Like most massage chairs, the Oki OS-4000CS is built with a full-body airbag system that offers comfort throughout the body. The difference with the OS-4000CS is that it only uses 24 airbags to cover the same surface as the previous version. The Osaki OS-4000CS massage chair offers airbags on the shoulders and armrests to provide a compression massage that helps promote circulation with the arms and hands. Airbags in the hip and waist area inflate to squeeze the hip area while pressing the waist’s back to improve the lower back massage. The Osaki OS 4000CS massage chair offers air pockets in the legs and feet to promote circulation in the lower half of the body and apply foot massage, allowing the feet to accumulate in the pressed part. The pressure is exerted to stimulate acupuncture points on the feet.
  • Modes: This massage chair also features various massage styles, such as kneading, tapping, rolling, and shiatsu. You also have dual action massage, and also you can select one spot on the back or of the back area and have those manual style massages go in that specific area. Great for tight neck and shoulders.
  • Programs: There are six automatic programs to choose from that combine all the different massage styles in a unique way to relieve the whole body. This includes an exclusive hip balancing function that will help you relax your lower back muscles. Osaki OS 4000CS massage chair includes 4 of the most popular massage styles and the ability to combine them to take your manual massage experience to a whole new level. These massage styles are Kneading, Tapping, Shiatsu, and Rolling.

There is vibration in the seat as well on this massage chair.
