The Osaki OS-4000 Manual View PDF
The OS-4000 massage chair features beautifully updated upholstery and includes Zero Gravity, a 30 inch Roller Stroke, Body Scan Technology, S-Track Massage Robot, full body air massage, seat vibration, and heat therapy for your back.
Equipped with the latest technology, it allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage hitting all the key areas. Regardless of your body type, this highly advanced chair will self-adjust making each massage experience feel customized.
The OS-4000 Zero Gravity massage chair is ergonomically designed to contour a variety of spine shapes. The Spine curvature is unique from one individual to the next. The S-track system allows the roller heads to massage along the back from the neck down to the lower spine with a consistent pressure in the massage, along with a comfortable support. The typical massage tracks, being linear, create an inconsistency in pressure applying weak massages in the neck and lower back.
Inspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This also reduces the vertical stress on the spine. There are 2 stages of zero gravity, the 2nd being more reclined. Study show that when the legs are at or above heart level, it promotes better circulation.
Next Generation Air Massage Technology
The airbag massagers have been upgraded and engineered, reducing the number of airbags and valves but at the same time increasing the surface coverage. Less power is consumed and runs more quietly with the reduction of air pumps and valves, allowing for a more tranquil massage experience. The material used to create the air bags have also been modified with industrial grade material for durability, yet soft and pliable to provide comfort and consistency.
Lower Back Heat Therapy
There are 2 heating pads, one on each side in the lower lumbar area. The heat therapy is a great compliment to roller and airbag massage. The heating pad is not intended to be use for more than 30 minutes a day or the duration of a massage preset program.
Located on the top right of the main remote, you will find a compact wireless remote allowing you to control the main features of the chair without having to struggle to reach the main remote in the reclined position.
The calf and foot massager is capable of making adjustments according to each individual's leg length, ensuring that the massage air bags are concentrating on the correct areas. At the start of the massage, the legs will fully extend out and then retract. Once the foot massager has reached the desired length, firmly press your toes down to indicate the chair to stop.

The massage chair massage intensity has been measure at 7-8 in regard to back massage intensity. Warranty: The chair comes with a 1 year plus 2 year additional parts factory warranty.
This chair is fantastic everyone in my family enjoys using it. Since we bought it I probably use it about an hour a day.
Very comfortable and I love the zero gravity. The selections are awesome but myself I could use it to have another 1or 2 more degree in intensity but my husband likes it the way it is so I just think that I can handle more lol. Love it I sat in it a hour first night couldn’t get out.
I just received this today. Delivered on time and it was every bit as simple to assemble as advertised. Ths is my initial review and wanted to make public that this chair exceeded all of my expectations. It is always risky buying a product online because you don't have the opportunty to judge workmanship and overall quality until after purchase. In one short statement, this is a beautifully made, high quality product. This looks and feels a lot more expensive than the price and I base my comparison reference from looking at competitor models in stores that cost several times more. I would judge that this chair is at least equal to models I have physically seen that cost over $10,000. If you are looking for a full body massage chair, this will not disappoint.
