Zero Gravity

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. There are two stages of Zero Gravity, the 2nd being more reclined, relative to the seat base.

The Zero Gravity position relieves pressure on the spine, relaxes the neck and back, increases blood oxygen levels, and expands lung capacity. When reclined fully, to where your legs are higher than your heart level, the therapeutic effects are incredibly effective and may be felt immediately.

New! Foot Rollers

Located 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. Additionally, the airbags inflate and deflate simultaneously on the sides of the feet, which push the bottoms of the feet into closer contact with the foot rollers. This results in a much deeper foot sole roller massage. This is a perfect feature for those who have sore and tired feet.

Computer Body Scan: Automatically Detects the Whole Body Curve

Equipped with the latest technology, the Computer Body Scan allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage that hits all the key areas. Based on your weight and height, the OS-4000T makes micro-adjustments which makes each massage feel like a customized experience.

Designed with a S-Track Movable Intelligent Massage Robot

Ergonomically designed with the shape and curvature of the human spine in mind, the S-Track Robot provides support to your neck, back and lumbar area, according to your body curve. This, in turn, increases the effectiveness of your massage.

Next Generation Air Massage Technology

Osaki has re-engineered and has 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 airbags but have increased the volume and surface area of massage. By doing so the total number of working valves has drastically reduced from the prior model. This ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs on the market.

The OS-4000T includes 38 airbags, covering all the areas not massaged by the roller system. This includes the outer shoulders, arms, calves, the waist/hips, inside the seat, and inside the neck/head pillow. The combination of the OS-4000T’s back rollers and airbag system makes this system a full body massage chair — covering everything from the head all the way down to the bottoms of the feet.

Air & Vibration Arm Massage

Along with mechanical advancement and material upgrades, the OS-4000T now features a durable spandex pocket which allows you to massage your arm and hands. The bottom portion of the arm massager has been lined with small rubber bumps to invigorate the senses. Sit back and relax as the the airbags compress on the top and bottom of your forearms and hands.

Auto Recline and Leg Extension

The fully automatic, luxurious OS-4000T is designed to make every movement effortless. The simple to use remote control allows you to operate the foot extension, leg rest, recline, and the Zero Gravity position.

Wireless Controller

Located on the side 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 while in the reclined position.

Comprehensive Foot & Calf Massage

The OS-4000T features 14 airbags that inflate and apply a compression massage for your calves and feet. In addition, spinning rollers are located along the bottom foot massager that apply a concentrated pin-point kneading massage.

Shoulder, Lumbar & Hip Squeeze

In the upper to mid portion of the chair, the airbags are programmed to inflate at independent times, which causes the body to twist, creating an enjoyable deep stretch. Stretching is also applied to the shoulders, lower back, hips and thighs.

Lower Back Heat Therapy

The OS-4000T’s lower back region features two heating pads that enhance the massage experience. Research has shown that lumbar heat therapy provides relief to those suffering from lower back pain. It does so by increasing the body’s oxygen flow, which in turn plays a role in healing damaged tissue. Heat therapy also forces your lower back to press more firmly against the backrest for a stronger and deeper massage.

Easy to Use LCD Display Remote

The OS-4000T remote boasts one of the largest viewing screens to easily visualize what functions the chair has activated. There is also a flip down cover to access the manual functions of the chair. The remote allows you to select the massage type, intensity, speed and location.

In the manual mode, you can also independently select a specific area of the body you want the chair to massage with the rollers and/or the airbags. Manual massage techniques include kneading, tapping, shiatsu, rolling, combination and Swedish.

Designed with Five Levels of Speed & Intensity

The air intensity of the airbags can be controlled up to 5 levels. Choose from mild to strong for both the back and lower body. 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.

The speed in which the massage heads move can be controlled up to 3 different speeds, ranging from slow to fast.

Three Types of Width Adjustable Settings

Choose from Wide, Medium & Narrow. If you want the massage heads to concentrate on the outer shoulders and outer back, choose the wider option. If you want the massage heads to be closer together near the middle of the back, choose the narrower option.

Auto Leg Scan

The calf and foot massager is capable of making adjustments according to each individual’s leg length, ensuring that the massage airbags 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 down along the toes to indicate to the chair to stop.

Seat Vibration

Located in the seat base is a vibration plate that provides a vibration massage to the back of the thighs and buttocks.

Six Unique Auto Programs

Choose from the straight-out-of-the-box Muscle Relief, Thai, Stretching, Anti-stress, Demo, Neck/Shoulder, and Back/Lumbar options.

Six Customized Massage Styles

Options include Rolling, Kneading, Clapping, Shiatsu, Swedish and Combo.

Manually Pinpoint Your Massage

You can select to receive a (1) Full Body massage; (2) target a Partial region of the body; or (3) target a Fixed, specific area of the body.

Auto Timer

5-30 minutes of usage can be programmed. You can increase the duration of the massage in 5 minute increments, up to 30 minutes. This is a safety measure to ensure that if you fall asleep, the massage will stop running to prevent any injuries.

Massage Chair Targets

The OS-4000T is an all-in-one mid-strength massage chair that targets the back, shoulders, neck, arms, hands, hips, lumbar, buttocks, thighs, calves and feet.
