Osaki OS-4000T Massage Chair
The Osaki OS-4000T Massage Chair, an enhanced version of the popular OS-4000 model, introduces new foot rollers to its array of features. This chair offers an ergonomic S-track design, complete with Zero Gravity positioning, 30" S-track length, body scan technology, full-body air massage, seat vibration, and lumbar heat therapy. Crafted for ultimate relaxation and well-being, the Osaki OS-4000T Massage Chair boasts an array of capabilities to soothe your body and mind.
Osaki OS-4000T Features
Truly Ergonomic S-Track
The Osaki OS-4000T Zero Gravity Massage Chair aligns with the natural S-curve of the spine, providing comprehensive support for the neck, back, and lumbar regions. This ergonomic design enhances massage effectiveness by enabling individual spinal discs to separate and decompress, facilitating nutrient flow to disc tissues.
Quad Style Roller
Featuring soft quad style rollers that emulate the human thumb's sensation, the Osaki OS-4000T massage chair enhances the massage experience. The roller width can be adjusted to medium or narrow modes, catering to specific penetration needs for a deeper effect. The rolling motion targets main meridians on the back, acanthus, forehead, and head's top, clearing acupuncture points along these pathways.
Body Scan Technology
With the press of a button, the Osaki OS-4000T scans your body, automatically calibrating rollers for an ideal massage experience. This technology also adapts the chair's height and width to match your body. Coupled with the S-Track Massage robot, the OS-4000T targets problem areas like the neck, shoulders, and lumbar region, enhancing and personalizing the massage.
Zero Gravity Technology
The zero-gravity feature in the Osaki OS-4000T is remarkable for its effectiveness and numerous benefits. As the chair reclines and elevates legs, a sense of complete weightlessness is achieved. This position yields various health advantages, including spinal pressure relief, neck and back relaxation, reduced cardiac pressure, improved circulation and oxygen levels, and expanded lung capacity.
New Foot Rollers
The Osaki OS-4000T massage chair introduces comforting reflexology massage to the foot soles, targeting acupressure points to relieve body-wide tension. Spinning rollers knead away foot discomfort, while airbags enhance circulation, making this an excellent rejuvenating feature for tired and sore feet.
Next Generation Air Massage
The Osaki OS-4000T massage chair employs 38 re-engineered airbags utilizing next-generation technology. Through innovative design, Osaki maximizes air volume and surface area, minimizing chair stress and enhancing mechanical reliability.
Arm Air Massage
Featuring enhanced materials, including durable spandex, the arm massaging area incorporates small rubber bumps along the bottom portion. This invigorating design, coupled with four airbags, compresses both forearm and hands' upper and lower regions.
Calf and Foot Massage
With 14 airbags inflating along the legs' sides and back, a compression massage is delivered to the calves and feet. Spinning rollers in the foot massager offer targeted pin-point kneading massage.
Shoulder, Lumbar, and Hip Squeeze
The chair's upper to mid-portion includes 13 airbags programmed to inflate independently, inducing body twists and deep stretches. This stretching action encompasses shoulders, lower back, hips, and thighs.
Automatic Programs
The Osaki OS-4000T massage chair provides 5 automatic and 3 localized programs. The Automatic Programs cover full-body massage experiences, including Muscle Relief, Thai, Stretching, Anti-Stress, and Demo. Localized programs focus on specific regions: Neck and Shoulder, Back and Lumbar, and Full Air.
Manual Programs
The flexibility of Manual Programs allows personalized massage relief. Enjoy Tapping, Clapping, Shiatsu, Rolling, Swedish, and Kneading techniques, with adjustable intensity and strength to tailor the massage to your needs.
Lower Back Heat Therapy
Enhancing the massage experience, two heating pads in the chair's lower back region provide lumbar heat. This feature loosens muscle tissue while elevating core warmth, promoting circulation.
Wireless Controller
Conveniently located on the main remote's back, a compact wireless remote controls primary features of the Osaki OS-4000T massage chair, eliminating the need to struggle reaching the main remote while in a reclined position.
