Osaki OS-4000 Massage Chair - Floor Model

Osaki OS-4000 Zero Gravity Massage Chair

Everything about the OS-4000 massage chair caters to you. From the moment you start a program, the chair maps your back and adjusts to your height so that you get a uniform massage across your whole back. The easy to use remote provides several fine-tuning adjustments, so you can adjust the settings to your personal preferences, including the addition of heat therapy and turning the foot rollers on and off. 

Why Choose the Osaki OS-4000?

Zero Gravity Technology

Zero gravity has a number of benefits that improve every aspect of your massage. Reclined in the zero gravity position, your joints and spine are more easily able to decompress, releasing tension in those areas, while focusing the majority of your body weight on the backrest so that you gain a deeper benefit from your back massage as well without your massage chair having to work any harder.

Zero gravity was introduced by NASA a few decades ago and is the position that astronauts sit in as they are launched into space because it reduces stress on the body and minimizes gravity’s influence. This induces a sort of weightless feeling in some, which improves your relaxation even more.

Body Scanning Technology

Like all Osaki massage chairs, when you first choose a massage program, the OS-4000 glides the massage rollers up your back to map your distinct shape and height. That way it can provide a more uniform massage catered to you that massages you everywhere you need it, and nowhere that you don’t. The rollers are adjusted with every massage to ensure that every user gets a personalized massage, every time.

Elaborate Airbag Compression Massage System

Sporting 48 airbags, the air compression massage system of the OS-4000 provides a full body massage experience that is unparalleled. Adjust the intensity from the remote to ensure you are getting the perfect amount of massage for your preferences. These airbags strategically placed throughout the massage chair bring relief to the extremities in the form of air compression massage, which helps loosen up tense muscles as well as improve circulation throughout the body. Airbags are placed in the head, shoulder, arms, hip & seat, legs and near the footrest, and are used by themselves are in tandem with the massage rollers in the backrest and footrest to give you a more vigorous massage. As the shoulder and foot airbags inflate they push your back onto the backrest, or your feet onto the foot rollers thereby improving the massage experience for your whole body.

Truly Ergonomic S-Track

This style of massage track was designed to more closely mimic the curvature of the human spine, allowing it to give a much more uniform massage across your whole back especially in areas like the lower back and upper shoulder areas. Massage chairs built with a straight track often neglect these areas.

Comprehensive Human Hand-Like Massage

The Osaki OS-4000 has been designed with a quad style massage roller that more realistically mimics the motions and massage that a human hand might provide. This style roller offers many levels of personalization, from the width of the roller to the speed and intensity, as well as the style of the massage. All of which is easily accessible from the flip down tab on the panel remote.

Heat Therapy

Heat can be added to your massage to help loosen up the large muscle groups in your back and lumbar. Two heating pads on either side of the backrest apply heat to your back which helps improve your overall massage experience.

5 Massage Styles

The Osaki OS-4000 zero gravity massage chair is pre-programmed with five massage styles that provide the basis of the 6 massage programs.

• Kneading – This is the most popular massage style and is adept at relieving knots, and stress in tense muscles in the back and feet.
• Rolling – This style mimics the human massage motion by sliding up and down your back, this focuses more on the muscle groups directly adjacent to the spine.
• Tapping – This massage style provides gentle tapping along the spine and is perfect for relieving tension at the back of the head and neck.
• Clapping – This massage style feels like a palm massage across your back and is useful for relieving muscle pain.
• Shiatsu – Characterized by small circular motions, this style is best for relieving tense shoulder muscles.

Easy to Use LCD Panel Remote with Wireless Mini-remote

The Osaki OS-4000 remote features an intuitive design that allows you to access every facet of your massage quickly and easily, including all massage adjustments under the flip down tab. Each of the 6 massage routines that are pre-programmed into the chair are easily accessible from this remote.
