The Osaki OS-4000T is a full function massage chair that automatically detects the natural curvature of the human body and adjusts the massage to fit. The Zero Gravity position elevates the legs above the heart and more evenly distributes your weight. The OS-4000T also features hip air massage, seat vibration massage, neck and shoulder air massage, air and vibration arm massage, heat therapy for your lumbar/lower back area, and foot rollers.
Choosing your massage is easy with the 7 unique auto programs: Muscle Relief, Thai, Stretching, Anti-stress, Demo, Neck/Shoulder, and Back/Lumbar, all with one touch of a button. Massage combinations are endless with 6 of the most desirable techniques: Shiatsu, Swedish, Kneading, Clapping, Rolling, and Combo. Add to that 5 speed and intensity settings and you have complete control of your massage for ultimate relaxation.
There is also automatic massage settings for the upper body (shoulder, neck, back and lumbar) and the lower body (buttock, thigh, calves and feet). You can manually adjust the massage for the upper body with three options: full body, partial and fixed.
Product Description
QUICK PRODUCT FEATURES
- 2-Stage Zero Gravity Massage Chair: The Zero Gravity recline position places your legs above your heart and evenly distributes your weight across the chair. This position has been found to relieve pressure on the spine, relaxes the neck and back, increases circulation and blood oxygen levels, expands lung capacity, and helps correct spinal alignment
- S-Track Movable Intelligent Massage Robot Design: The OS-4000T’s quad-style massage rollers in the backrest of the chair follows the natural S-curve of the human spine to evenly target the neck, shoulders, mid and lower back with the same massage pressure. Many massage chairs are designed with an uncomfortable straight track that provides an intense massage in the mid-back region and poorly targets the neck and lower back regions. The S-Track Robot, however, provides a uniform, hand-like massage on your neck, shoulders, back and lumbar region
- Advanced Computer Body Scan Technology: The OS-4000T scans your entire body prior to your massage to customize it specifically for your body type and size. The chair’s technology now allows the rollers to map the back curvature with more accuracy than ever before. Plus, you can make micro adjustments as needed to bring a more humanistic and scientific massage approach
- Seven Unique Auto Programs: Choose from Muscle Relief, Thai, Stretching, Anti-stress, Demo, Neck/Shoulder, and Back/Lumbar
- Six Manual Mode Techniques: Create your own custom massage and choose from several massage roller techniques, including Shiatsu, Swedish, Kneading, Clapping, Rolling, and Combo
- New! Foot Rollers: The OS-4000T now uses reflexology technology to target the pressure points as mechanical rollers spin underneath your feet. Foot rollers stimulate circulation and soothe tired feet. Foot rollers are a new addition to this model
- 38 Airbags: The OS-4000T wouldn’t be a full body chair without the addition of air massagers. The 38 massagers are pumped with air and wrap around the regions of the body the S-Track roller system can’t reach, providing a rejuvenating compression and stretch. The airbags massage the outer shoulders, neck/head, arms, hips/waist, buttocks, hamstrings, calves, and feet. You can choose from 5 intensity levels to customize the air massage strength to your preference
- Seat Vibration: A mild vibration targets the thighs and buttocks inside the seat. A vibrational massage relaxes muscles, promotes blood flow and releases tension
- Updated Upholstery: The OS-4000T features updated upholstery not found in the previous model, the OS-4000. The improved synthetic leather material is designed to be more durable than its predecessor
- Lumbar/Lower Back Heat Therapy: The OS-4000T’s built-in heating pads provide relief to those suffering from lower back pain by increasing the oxygen flow to aid in healing damaged tissue. Heat therapy also forces your lower back to press more firmly against the backrest for a stronger and deeper massage
- Automatic Massage for the Upper Body (shoulder, neck, back and lumbar) and the Lower Body (buttocks, thigh, calves and feet)
- Ships in 2 Boxes: The OS-4000T is shipped in two (2) boxes — a big box that contains the base of the chair, backrest, foot ottoman, and remote. A separate, smaller box contains the chair’s side panels

DETAILED FUNCTIONS & FEATURES
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.

Deborah Nguyen –
BEST INVESTMENT EVER!!I’ve been having massages every 2 weeks for almost 3 years due to a back injury and overtime that became very costly! With the purchase of my Osaki 4000t massage chair I’ve been having at least 2 massages a day! My back has never felt better and I’m able to expand my horizons into other holistic healing sessions such as cupping or acupuncture and ending off a great session with a heated massage! Again, best investment ever! No regrets!!
Ryan Rackliffe –
This chair has exceeded my expectations and really puts itself in a high-end category at a reasonable price. It is loaded with features and has a nice appearance. The air and roller systems work well and truly gives a great massage.
Rosanne Lehnen –
I purchased the Osaki OS4000T Zero Gravity Massage chair for my husband's birthday. He is an independent owner operator and spends countless hours driving. With that being said when he is home, this chair soothes the aches and pains in his lower back, tired muscles in his legs and feet, helps circulate blood flow due to long durations if sitting, and massages his feet. And added plus is the heating option, helps relax and soothe a tired body. He absolutely loves this chair. Great quality for a great price. Even our granddaughter loves it. Along with me! Definitely worth the purchase. I even let our family and friends experience the massage chair. Hands down, a huge win.
Thanks for an awesome chair at an awesome price.
Sharon Dix –

Terry Fritz –
We have owned an OSAKI 4000T for ~8 years and it it is still as comfortable and reliable as it was when new.
The customer support is one of the best I have encountered anywhere
If you buy something other than an OSAKI you're buying 2nd best for the same price
:>} It's the best
Jim Swindell –
Love this chair. Especially like the zero gravity, anti stress and calve massage. Thank you Helen for getting this for us, really helps our back pain. Also helps relieve muscle cramps in our legs.
Keith Kulman –
I have owned this chair for three months now. The only night my wife and I have not used it was on the Super Bowl. This chair was the best purchase we ever made. We both feel spoiled knowing that every night we get to relax like this. If you are reading this it means you are doing the same thing I did three months ago. You have come to the conclusion that this chair, at this price point, seems to be the best one. I can tell you that this is one purchase that both my wife and I do not regret. DO IT! The assembly took us 30 minutes, super easy, and the build quality is solid. Congrats on your new life after you buy this chair.
Wendy –
Great chair! Great service! soooo glad i found this site! I had been looking for over a year, and this was the best price, hands down!
Thank You!
Larry Dorsey –
We purchased the Osaki 4000T in December 2017. The chair delivers on what is promised and is of excellent quality. I assembled the chair with the help of my son-in-law in under 30 minutes. It was not at all difficult. The key selling point for our purchase was massagechairdeals.com customer service. They were knowledgeable and most helpful in our research of the products. They made the entire process easy and comfortable. Thanks for a great product.
