Many massage chair models may pretend it has got it all.
Not to mention that most of the budget massage chairs on the market today have the appearance of luxury equipment that provide the best massage with a human touch experience but in reality lack even basic features.
A few selected brands were able to offer premium features even in its cheaper models to attract potential customers.
Osaki massage chair brand packed a few great features in some of its models.
That’s why we decided to provide you with the Osaki OS-4000 massage chair review along with a quick comparison of Osaki's other models.
Osaki brand may sound familiar to you.
Let's find out if this brand did a good job with this model...
We will look at all the features and the drawbacks of one of the most popular and best rated massage chair.
And for the full overview of Osaki models, read our guide here.
Affordable and packed with special features, could the Osaki really have it all?
A popular brand, OS-4000 has a selection of four different models with features that vary from model to model.
The massage chairs offer numerous features. Either for a more serious user to an occasional hobbyist, the Osaki OS-4000 is highly functional for the price range.
Main Features (All Models Share)
There are four different Osaki OS-4000 models, with OS-4000 being the cheapest.
We’ve included a list of features for each model as well as their downsides.
Of the four 4000 models, this one is the most popular one.
On the low end of the Osaki price range, this unit offers quite a lot, but at the same time, the S-track design might not be too appealing to some.
Here’s a list of all its features:
OS-4000 comes with airbags in the arm, shoulder, hips, lumbar, heating pads, feet, and calves areas.
The air massage is a quite common feature with low-budget lift chairs.
Zero Gravity Feature
Two levels zero-gravity, a very beneficial feature because it enables a more thorough, deep tissue massage.
It relieves the pressure from the spine and helps muscles to relax.
Dimensions: 46L x 32W x 47H
Leg Scan System
The automatic leg scan feature means that the massager automatically adjusts according to the legs of the users.
This makes for a more intense and thorough leg massage.
This feature is not available with the Osaki 4000LS AND 4000CS.
It is provided for the lumbar area only with all four models.
Various Massage Techniques
There are eight pre-set massage techniques: circulation, 6 massage programs healthcare relax therapy, smart circulation, demo, neck and shoulder, full air, and lumbar.
With 6 massage styles (Rolling, Kneading, Clapping, Shiatsu, Swedish, and Combo) it is quite extensive in what it offers.
The users can choose from five intensity levels and five different massage speeds.
An additional touch is a manual mode function, which enables users to combine their ideal massage by choosing from the style and foot massager, speed and intensity, and compression massage duration.
Two Remote Controls
There are two remote controls for the OS-4000: a full-size remote control with an LCD screen and a wireless mini hand-held remote.
The two main remote controls come only with this model and the OS-4000T.
An In-Built Safety Feature
An automatic timer is a safety feature. When the user sets the timer, it turns off automatically if the user falls asleep during the massage.
The OS-4000 weighs 214 lbs. And it’s recommended for people up to 265 lbs. And 6 ft. tall.
Everyone who’s higher than this might not be accommodated very well in the chair.
This model has all the same features as the previous model, but it comes with an additional upgrade.
It also has an S-track massage which may be undesirable for some, but the upgrade is quite interesting:
Reflexology Foot Massage
Apart from the number of airbags in the feet and calves’ area, it also contains two rows of massagers which provide a deep foot and calf massage.
This is a plus for anyone who spends a lot of their time on their feet.
This feature is available only with this and the next model, Osaki OS-4000LS.
The chair weighs 214 lbs. And is able to accommodate users up to 265 lbs.
The OS-4000LS has similar features to the previous two models, but it comes with a few extras and a few changes as well.
One of the most important differences is perhaps the L-track design.
While the S-track is not too bad and it provides a solid massage, the L-track follows the spine from the neck to the glute area, covering a much wider surface than the S-track.
The L-track feature is available with this and the OS-4000CS.
Adjustable Shoulder Massage
The OS-4000LS has the ability to adjust the width of the shoulder massage. It offers three-width options to accommodate more users.
This feature is available only with this model and the OS-4000CS.
Another welcome addition to the OS-4000LS is the space-saving technology.
This can be a big plus for all those who have limited space. The 4000LS is very efficient space-wise.
All you need is 4 inches of space behind the chair for it to recline fully.
LCD Remote Control
This model comes with a LED-screen remote instead of a full-size controller, but it is easy to use.
This way the users can adjust the massage while they’re in the reclined position already.
There is no leg-scan technology as with the first two massage chairs, but it has a spring-loaded ottoman, which is able to adjust to the users.
Deep Tissue Massage
A deep tissue massage is a feature normally available in a zero gravity position.
But OS-4000LS has a deep tissue massage pre-set programs healthcare without any reclining required.
It weighs 272 lbs. And is able to accommodate users up to 300 lbs.
Very similar to the OS-4000LS model, this unit is different by only one feature. It doesn’t offer the reflexology foot massages.
Some users may be willing to overlook this downside, but for those who are specifically searching for good feet and leg massage, this lack could be a minor disappointment.
Apart from that, the OS-4000CS weighs 272lbs.
Details About the Osaki Massage Chair Company
The Osaki massage chair comes from an off-brand company of the same name. It is made in China.
Made of synthetic leather, the chair has a 3-year warranty on parts and labor. Users have the option to purchase the additional warranty; you can find more on their website.
We’re not completely sure about the warranty because in some cases the customers stated that their chairs came with a 1-year warranty. It can be delivered to 48 states, excluding Alaska and Hawaii.
Potential customers are advised to order the additional White glove delivery because this unit is very heavy. The fee would be $250.
This model is delivered in two boxes. The assembly is not too difficult, but the parts are heavy, two people are recommended.
You can find the downloadable manual here.
Back rollers may not be intense enough for some people. The annoying beeping noise coming from the controller is inexplicable.
While it tries to indicate something, which remains unknown, some users were not able to enjoy the relaxing massage because of an occasional beeping sound.
According to many reviews, this is not a matter of being resolved anytime soon. Due to a height issue, we’d suggest potential customers try the Osaki massage chair before purchasing.
There seem to be some problems with users taller than 6 ft. They have complained the chair cannot accommodate them properly. Contact the company for additional information on their showrooms.
Are Massage Chairs Dangerous?
Massage chairs do not pose a significant risk of causing accidents or injuries, according to medical professionals. In fact, a survey of more than 2,000 people in Canada and the United States found that of the 2,000 people who said they’ve ever had an injury from a massaging chair, only 2 percent reported suffering a serious injury. The latest data from the Consumer Product Safety Commission (CPSC) reported 12 deaths and more than 300 injuries to Americans from massaging chairs over a span of more than two decades. However, the CPSC reported only five incidents involving children under the age of 15 during the same period.
According to a report on Racked, the CPSC only reported the incidents to the public because it failed to submit data in a timely fashion, with some of the incidents dating back to the mid-’90s. Last year, the CPSC urged the public to stop buying and using the Varidesk Aeron, toll-free shipping, and fully collapsible zero-gravity massage chair. Although the company said it was issuing a recall for the chair because of issues with the motor mount, which connects to the seat, Consumer Reports noted that the mechanical parts were never designed to fail.
How Do I Connect Bluetooth to Osaki Massage Chair?
The Osaki massage chair utilizes Bluetooth technology, allowing you to connect it to your smartphone using your audio settings, as well as to your home entertainment system using either Bluetooth or a home wireless connection. The Osaki massage chair also has two charging stations. If the batteries in your Osaki massage chair are running low, simply plug the chair into the docking stations and let it charge. Your Osaki massage chair will also automatically restart when it is connected to the docking stations. Double-sided cordless hand grippers.
Is Osaki a Good Brand?
If you're going to go from zero to hero, you may as well give it a winning product to celebrate! That's what's happening with the Geodon. The company is using Geodon in several clinical studies looking at its use for Alzheimer's patients, proving that their drug can be a drug for use after a cure has been found for the disease. This clinical data must be very encouraging indeed since the U.S. Food and Drug Administration has approved Osaki as the first Alzheimer's drug in six years.
Osaki was also recently granted Priority Review Status, which speeds up the approval process for new medications. What kind of treatment will Osaki be used for? We can't be sure yet. Check back next week to read about one of the latest treatments for Osaki ergonomic s-track with wireless remote that's just recently become available in Japan, and then come back and read about one of the latest treatment options for Alzheimer's that was just approved by the FDA.
Frequently Asked Questions
Is Osaki a Chinese Company?
Osaki is a brand that specializes in massage chairs and other wellness products. It is often associated with Japanese design and engineering, but it is important to note that Osaki massage chairs are not manufactured in Japan. Osaki as a brand is based in the United States and its products are manufactured in various locations, primarily in China and Taiwan.
While the brand name "Osaki" might sound Japanese, it is not directly tied to Japan in terms of manufacturing origin. Many massage chair manufacturers, including Osaki, have chosen names that evoke a sense of quality and precision often associated with Japanese products.
The massage chairs produced by Osaki are known for their advanced features, multiple massage techniques, and innovative designs. These chairs are developed to provide relaxation and therapeutic benefits, regardless of the manufacturing location.
In summary, while Osaki massage chairs are not made in Japan, they are associated with a range of products designed to offer massage and wellness experiences, with manufacturing primarily taking place in China and Taiwan.
What Country Makes the Best Massage Chairs?
Determining which country makes the best massage chairs involves looking at a few factors. Japan and the United States have been key players in making top-quality massage chairs.
Japan is known for starting the whole massage chair trend and introducing advanced features like shiatsu massage techniques and body scanning technology. They laid the groundwork for the modern massage chair industry.
The United States also contributes by focusing on designing and engineering advanced massage chairs. While the chairs might be made in different countries, American companies are big on creating chairs that can be personalized and use the latest technologies.
But here's the thing – good massage chairs can be made in various countries, including China, Taiwan, and South Korea. These places have a lot of experience making electronics and wellness products. The quality of the massage chair really depends on the brand, how it's designed, and the manufacturing standards they follow.
Remember, what makes a massage chair the best varies from person to person. It's a good idea to consider things like features, design, what other users say, and the reputation of the brand instead of just where it's made.
Four popular massage chairs come with four different review results.
The OS-4000 has the most reviews, and for a budget chair, it offers a surprising number of features, such as automatic leg scan and heating.
On the other hand, some basic features, such as the L-track design are already available in the massage chairs in the same price range, such as RelaxOnChair MK-II plus, or Kahuna LM6800, which are above all also FDA approved medical devices.
The Osaki company might have been too quick to conclude that the customers will be satisfied with less for the same amount of money. The other two models from Osaki, namely the OS-4000LS and OS-4000CS may be what you need in a different price range.
