Unique Foot RollerLocated on the bottom of the feet are 2 rows of spinning reflexology massagers which provide a soothing kneading style application. As the rollers spin it will stimulate acupuncture points and as the air bags inflate it will generate a much deeper massage along the bottoms of your feet. |
Zero Gravity Massage:
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 feature improves spinal decompression and decreases muscle tension of the spine. There are 2 stages of zero gravity, the 2nd being more reclined. When reclined fully, to where your legs are higher than your heart level, the therapeutic effects are incredibly effective and may be felt immediately.
Next Generation Air Massage Technology:
Osaki OS-4000T has re-engineered and developed the next generation of air massage technology, streamlining the air massager to a lower count. Through innovative engineering, we have reduced the total number of air bags but have increased the volume and surface area of massage. By doing so the total number of working valves has drastically reduced from prior model. Which ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs in the market.

You can also independently select the area of airbag massage. The manual mode massage includes kneading, tapping, shiatsu, rolling, combination and Swedish.
• 3 Levels of Intensity for the massage - The roller heads that apply the massage to the back, can be extended outwards causing the rollers to press more firmly along the back. This will result in a more vigorous massage.
• Massage Speed Control - The speed in which the massage heads move can be controlled up to 3 different speeds, ranging from slow to fast.
Auto Leg ScanThe 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 chair will fully extend out and then retract. Once the foot massager has reached the desired length, firmly press your totes down to indicate the chair to stop. |

OS-4000T Massage Chair by Osaki Buyer’s Guide
The Osaki OS 4000T massage chair is a feature-rich, zero-gravity reclining chair built for total body wellness, pain relief, and restorative comfort. Designed with advanced technologies and a sleek, supportive design, this chair caters to users seeking therapeutic results from home—especially those with reduced mobility, spinal sensitivities, or muscle fatigue.
Zero Gravity Recline Promotes Circulation
The zero-gravity recline is one of the core features of the Osaki OS-4000T massage chair. By reclining the body into a position where the legs are elevated above the heart, it alleviates spinal pressure and boosts blood circulation. For wheelchair users or those with restricted mobility, this positioning can reduce lower back stress, help mitigate pressure injuries, and enhance relaxation.
Osaki OS 4000T Massage Chair’s S-Track System Enhances Back Support
The chair uses a scientifically engineered S-track massage system that mimics the natural curvature of the spine. This ensures that massage rollers glide along the back from neck to tailbone with consistent, therapeutic pressure. For individuals experiencing muscle fatigue or spinal misalignment, the S-track delivers continuous support while reducing discomfort from sedentary lifestyles.
Full-Body Air Massage
Equipped with 38 strategically placed airbags, the Osaki OS 4000T provides dynamic compression massage to shoulders, arms, hips, calves, and feet. This air massage function is especially useful for people with poor circulation, wheelchair users, or those recovering from injuries. The rhythmic inflation and deflation stimulate lymphatic drainage and muscle recovery in the extremities.
OS-4000T Massage Chair Advanced Body Scan Technology
Before each session, the automatic body scan system maps the user’s back to determine exact shoulder height and spine contour. This tailoring process allows the Osaki massage chair to adjust roller positions and pressure points based on each unique body shape, ensuring a massage experience that is both effective and safe for users of all sizes and needs.
Adjustable Footrest and Calf Massage Support
A motorized footrest extension system accommodates users of varying heights, allowing the OS-4000T chair to adapt seamlessly from smaller to taller users. Combined with calf airbags and foot rollers, this section provides targeted therapy to legs and feet. This is ideal for users who are often seated or standing for long periods, or who experience frequent leg cramping or neuropathy.
Osaki OS-4000T Massage Chair Heated Lumbar Support
The Osaki OS 4000T massage chair offers infrared lumbar heating to soothe tight lower back muscles. This heat therapy is particularly beneficial for individuals dealing with sciatica, chronic stiffness, or fatigue from prolonged wheelchair use. The warmth penetrates deep into tissue layers, enhancing the effects of the massage and promoting relaxation.
Personalized Massage Therapy
The OS-4000T offers a wide range of massage techniques including kneading, tapping, rolling, shiatsu, and Swedish-style strokes. With adjustable intensity and speed settings, users can tailor their sessions to meet their personal health goals, whether it’s for deep tissue relief, gentle relaxation, or targeted pain relief in a specific area.
