Rollers for the feet

There are two rows of revolving reflexology rollers at the bottom of the feet. These rollers offer a relaxing kneading sensation.

The acupuncture sites will be stimulated by the rotating rollers. When the airbags fill up, they will further massage the bottoms of your feet.

The Law of Zero Gravity:

The zero gravity position, which was inspired by NASA technology, is great for receiving a massage. This position aligns your back with your thigh for maximum comfort. The backrest supports the entire weight of your back when reclining in the zero-gravity posture. The intensity of the massage is maximized in this manner. This feature enhances spinal decompression and reduces spinal muscular tension.

Air Massage Innovation:

The OS-4000T Massage Chair has been redesigned by Osaki. The company has created the next generation of air massage technology. Osaki has also reduced the number of air massagers. We have lowered the overall quantity of airbags due to smart engineering. However, we have increased the massage’s volume and surface area. As a result, the Osaki os-4000t massage chair has a lower total number of operating valves than the previous model.

In comparison, the greatest intensity massage is really strong.

It is an excellent solution for folks who have more severe back problems than ever before. It’s not the only massage choice; there are five pace levels to pick from. Each massage program is paired with an adjustable pace level for every section of the body. This is a terrific approach to having a personalized massage and improves your whole experience.

Heat Therapy for the Lower Back:

Two heated pads in the chair’s lumbar region improve the massaging experience.

Shoulders, lumbar spine, and hips:
