Add to that 5 speed and intensity settings and you have complete control of your massage for ultimate relaxation.


What Makes the Osaki OS-4000T So Desirable?

New - Foot Rollers!

The OS-4000T provides soothing reflexology massage to the soles of your feet, targeting the acupressure points to relieve tension throughout the body. The spinning rollers knead away foot pain and discomfort while the airbags increase circulation.


Zero Gravity Technology

The zero gravity features on the Osaki OS-4000T is notable because it is so effective and touts many benefits. Simply put the chair reclines and lifts your legs until you are in a position of complete weightlessness. As you can imagine, your body is completely relaxed and in this position you gain numerous health benefits such as pressure relief from the spine, relaxation of the neck and back, less pressure on the heart, increased circulation and blood oxygen levels, and expanded lung capacity.


48 Multilayered Air Bags

The Osaki OS-4000T has 48 extensive air bags of various sizes that cushion your entire body to further enhance the zero gravity experience. With more airbags than the average chair, the massage technique is very close to that of the human hands, placing pressure strategically to enhance the overall massage experience. Each airbag is fitted to hug your body in total comfort from the neck to lower back, arms to the calves. There are 10 airbags in the feet, 10 in the calves, 3 in the seat, 2 in the back, 2 in the shoulders, 3 in the neck, and 3 in the hips. Paired with the human-touch massage rollers, the Osaki OS-4000T lets you enjoy a seemingly weightless massage unlike any other.

Osaki OS-4000 Massage Chair Airbags

Body Scan Technology

At the touch of a button the Osaki OS-4000T will scan your body and not only automatically adjust the rollers for the perfect massage but also automatically adjust the height and width of the chair to fit your body. Coupled with the S-Track massage robot, this Osaki OS-4000T is capable of specially focusing on problem areas of the body like the neck, shoulder, and lumbar regions customizing and enhancing the massage experience.


Truly Ergonomic S-Track

The Osaki OS-4000T Zero Gravity Massage Chair is ergonomically designed to follow the natural S-curve of the human spine. It provides support to both your neck and back, especially the lumbar area. This position increases the effects of massage as it enables each disc of our spine to individually seperate and decompress, allowing nutrients to enter disc tisses.

Comprehensive Human Hand-Like Massage

The Osaki OS-4000T is equipped with extra soft quad style rollers to mimic the feel of the human thumb, thereby enhancing the massage experience. The width of the rollers can be adjusted to medium or narrow mode to suit individual needs for better penetrating effects. The rolling manipulation helps dredge the main meridians on the back, canthus, forehead and the top of the head, along which the accupuncture points are distributed, to clear the collateral channels.


4 Unique Massage Functions


The kneading technique is performed by the rollers moving in a circular motion and is very useful in eliminating knots or tense muscle tissue.


Rolling mimics the human hand motion of sliding or pressing up and down the spine in a fluid motion. Used primarily at the beginning or end of the massage to warm the muscles and awaken the senses.



The tapping technique feels like the fingers tapping along the length of the spine, particularly good for eliminating headaches and tension at the back of the head and neck.


Clapping techniques are usually used to ease muscular pain, numbness, spasm and headache. The massage roller mimics the feeling of the palm patting the muscular tissue.


4 Unique Massage Functions

  • 5 Intelligent Massage Groups: Healthcare, Relax, Therapy, Smart and Circulation
  • 3 Partial Massage Groups: Neck & Shoulder, Back & Lumber, and Lower Body
  • 5 Unique Massage Styles: Swedish, Shiatsu, Vibration, Pulse Mode, and 48 Air Bags

Impressive Warranty

The Osaki OS-4000T is supported by one of the best warranties and is not voided by use in a commercial setting, making it a great choice for Chiropractic, Spa, and healing centers. If the chair can be used multiple times per day in a business, imagine how well it will stand up for home use. Osaki really stands behind the quality of their chairs.

Customer Reviews

Tight in the shoulders Review by Tim B
Bought this chair for a friend and he ended up not wanting it. After a week of use we enjoyed the chair but found that it wasn’t very deep. I'm also 6 foot and the fit in the shoulder area was pretty tight and uncomfortable. I felt like I had to squeeze into it. We ending up decided to exchange it to the Osaki Pro Dreamer, because we felt we would regret it if we didn’t. The Dreamer chair is much deeper in the neck and shoulder area, and the fit is much nicer in the shoulders. I do recommend that if your over 6 feet or have broad shoulders to look at chairs with more shoulder room. is also everything that I read. Their staff is outstanding and they made the exchange process as easily as it could be. I would recommend calling them if you have any questions.

Great value Review by Sammy P
We bought the Osaki 4000T in May and have been using it all the time. I originlly saw the chair at Costco but after talking to the Emassagechair staff they explained that the OS-4000T has foot roller and the OS-4000 does not. We liked the idea of the foot rollers, and they are awesome for tired feet. However, one thing we did notice after our friend used it was that if you are taller say 6' or higher you may find the chair a little tight. Other than that chair is great so far and it definitely helps with our aches and pains. (Posted on 8/9/2015)

Love this chair Review by Tired momma
I get have problems with my neck from standing in front of a computer all day at work. 20 minutes in the chair when I get home does wonders for me. Zero gravity, heated seat are terrific! Only disappointment is the head rest really doesn't do much except inflate. (Posted on 8/13/2014)
WONDERFUL!! Review by RJ
Oh how I love this chair. It is more than I was hoping for because there are so many different ways to use it! I have all my family rushing into the house to see who can use it first.

If I need deep muscle massage one day, I can get it. If I need just a soft air massage the next day, I can get that too.

I would recommend this to anyone who has a chronic pain disorder because it really helps the pain from my osteoarthritis and Fibromyalgia. It makes you forget the pain for a while, (Posted on 6/16/2014)

Noisy Review by Teaguer
The chair works well and provides a great massage. The zero-gravity feature is very relaxing. The issue I have with the chair is that it is becoming noisier all the time. The massage arms sound like they are grinding. I have contacted and they have helped me get in touch with Osaki to figure out what the issue is. (Posted on 4/17/2014)

Yippee Review by Deanna May
I feel like I got a steal of a deal on this chair---It does everything listed and more. I can't help but brag to all of my friends! They all want one now too. I got the new 4000T and my tootsies thank me every time I use my chair! I have the cream color and it looks stunning in my bedroom. My brother and my husband had it up and going in about 45 minutes (the manual is a little skimpy but it wasn't hard to figure out) and we've been relaxing to our hearts desire ever since. Thank you for making the purchase and delivery easy, easy, easy! (Posted on 4/14/2014)
hard to learn but well made Review by relaxer
it doesnt come with nor is a Users Manual available on line. what they offer is the name of the button but not a description of what it does. so the only way to know what you're doing is to push every function button and memorize the action = pretty lame. the chair is well made and works well. it could use more aggressive neck & shoulder functions. (Posted on 2/26/2014)
pretty good, hard to learn Review by relaxer
the chair overall is a good chair. but there is NO explanation or description for the operations. the users manual is anything but. the only way you know what buttons to push for a given massage is to push each button and memorize the results. neck & shoulder massage is the weak link. all other functions are great. chair seems durable and well made. (Posted on 2/26/2014)
Great chair for the money Review by docvel23
I gave this chair as a Christmas present to my husband and is absolutely heaven-sent. We all love the heating feature and the zero-gravity feature however, the reason why I'm giving 4 stars instead of 5 is because there are certain functions wherein you cannot do while your in zero gravity. Didn't make sense to us, but overall very satisfied. (Posted on 2/26/2014)
totally amazing chair Review by Charlie
Had the white glove service and loved it not having to deal with clean up or wondering if it's totally correct. The settings are great and def strong enough intensity wise. The only problem I have is kicking ppl out of so I can use it. (Posted on 2/7/2014)
I love the chair! Its great! Should buy! I placed the order and got it in 8 days. The delivery person delivered in my garage although it said curb side delivery! It has been almost 2 months that I am using this chair. My family loves this chair. You don't have to spend more money for 3D technology. The rollers in this chair are really strong. In the beginning, I used the optional padding in the headrest and the rollers did not feel strong enough, but as soon as I took it out, the rollers works really strong! You can also adjust the intensity. I recommended this chair to my friends and would recommend to everyone. Its worth the money! Don't think just buy it! (Posted on 1/25/2014)

The best online purchase I have ever made Review by Ted
My wife and I ordered the OS-4000 based on a recommendation by relatives who had purchased theirs from some months before and loved it. I must admit that any concern I had about ordering online was quickly removed by Heather and her professional manner. I ordered the chair and relaxed. I received messages that the order was completed, the chair was en route, the expected date of delivery, and exactly as scheduled the chair arrived, the gentlemen set it up and we were using it . It was the best order/shipping/delivery/setup we ever had. Thanks Heather and your staff/crew, you did everything you said you would, better than I could have expected. It is terrific and we intend to get one for our relatives soon, you'll be getting the order. (Posted on 9/24/2013)
This chair has lowered my pain level in a tremendous way Review by Gene
I have a severe pain problem taking heavy narcotics for many years. This chair has lowered my pain level in a tremendous way. I purchased the Osaki 4000 in hopes of giving me pain relief and it's unbelievable of what has been accomplished. I now am able to sleep. Before my sleep was interrupted four to six times nightly, not now! What can I say? Thank you for making my life so much more livable. Osaki is a wonderful massage chair and I highly recommend this chair with all it's wonderful features. Thank you, thank you. (Posted on 9/2/2013)
Highly Recommended Review by Jimmy
This chair is so good! I was a bit worried that I was going to be getting a strip down model because the price is so low but this chair has all of the features of the pricier chairs. I particularly like the zero gravity and use it in conjunction with the targeted massage on my back region. Feels great! I recommend this chair to all of my friends and family. (Posted on 5/28/2013)
Wonderful Review by BAKfromVA
My daughter owns this model and I have used hers a couple of times and it is a wonderful feeling to just lay there and let this chair do it's work. Although we live close to each other, I still plan to get a chair of my own. Just the thought of being able to get a full body massage anytime you want one and in the privacy of your own home is a great feeling so if you are in the market for a massage chair, I definitely rate this as a great one to consider. (Posted on 1/7/2013)
Very Amazing Chair! Review by Geno
It was very hard to try out a chair since we don't have a dealer within 80 miles so I took a chance after reveiwing several online. i choose the OS-4000 since it had all the features that I wanted. It was very easy for me to to assemble except the left arm uses "gray" colored air hose identifier as opposed to the right arm which uses green air hose identifier (per assy directions); gray-to-gray was correct. If you don't get an Email with tracking number within three business days of ordering, don't worry just call Emassagechair like I did. I got my tracking number over the phone from Heather and realized my tracking email was in my junk folder! So far we are very pleased with the quality and operation of the chair. (Posted on 12/17/2012)
Better than Brookstone Chair Review by Gina F.
Very cool massage chair. I had tried a chair at brookstone and saw that this was a comparable chair for much cheaper. So far the chair has been better than the one I tried and I'm very pleased. (Posted on 11/1/2012)
Incredile chair AND service Review by Jacky
I cannot boast enough about both the Osaki 4000 and the outstanding customer service from Emassagechair. I ordered the chair last Friday and it was delivered on Thursday. We chose the white glove service as the chair was going upstairs. I recommend the white glove service also for ensuring that the chair is assembled properly and in fully working order. I worked with Matthew at Emassagechair and he was most helpful answering all my questions without any pressure. Whether you decide on the Osaki 4000, which I highly recommend, or any other chair, definitely consider Emassagechair. Great prices AND phenomenal customer service. Have to go now and get back in the massage chair :). (Posted on 4/26/2012)
Purchased on eMassagechair Review by Rob V
I'm glad that I did not ask for the installation service. This chair is amazingly simple to assemble. It's basically 4 parts, (2) arms, (1) base, (1) back.

There are some reviews out there that state the massage is not forceful enough. Like other chairs, there are removable pads to increase the intensity of the massage. When in any one of the two "Zero-Gravity" positions, I had to turn down the force of the massage. The calf massage can be painful if you do not adjust the sensitivity of it. Common sense here. If its not forceful enough, turn it up. If its too forceful, turn it down.

The preset massages are great. I'd highly recommend this chair for anyone. It is easy to assemble and give a great massage. You can pinpoint it to any specific area as well.

Great chair, I'd rate it a 10. Definitely worth the money and thank you emassagechair for all the great help. (Posted on 1/20/2012)
Wonderful Chair/Wonderful Service! Review by LuckyInKentucky
There aren't many reviews available about this chair, but Heather answered all of my questions about the Osaki OS-4000. I placed the order and it arrived 8 days later in perfect condition. The chair feels amazing and I couldn't be more happy with my purchase. I opted for the 5-year full warrant and white glove delivery and they still had the cheapest price available anywhere! Tip, if you like a strong massage, take out the optional padding thats in the backrest. It really makes for a stronger massage! (Posted on 1/6/2012)
Great chair, everything I expected! Review by Robert D.
This was a birthday gift purchased for me from my business partner / best friend. The chair is everything I wanted and more. The communication from was great, the delivery came as expected and was a breeze. My sisters, mom and friends come over and the first thing they want to do is get a massage!

Thank you for a great chair... (Posted on 11/27/2011)
Great Review by Mitch
This Chair is amazing. I have only had it a couple weeks and it has already been a blessing to my back. I suffer from MS and have had very bad back pain; I was taking prescription pain pills and not liking how often I needed them. After spending 15 – 30 minutes a day in the chair I have not needed any pain meds for my back. The chair is also good for poor circulation in my legs. E-massage chairs was a great very helpful in my purchase and the chair came promptly after my order. Thanks. (Posted on 11/15/2011)
