In 2011, the introduction of the Osaki OS 4000 massage chair to the US market was received by budget-conscious consumers as good news.
The chair, launched by the same company that gave us the Titan massage chair line, is apparently have been inspired by the award-winning design of the luxurious Inada massage chairs.
In fact, it looks and almost functions like the original Japanese massage chair, but with one great difference: its price is less than half that of Inada’s.
How is it even possible? The answer is quite simple: Contrary to what it suggests, Osaki isn’t a Japanese company. Based in Texas, Osaki imports its massage chairs from a manufacturer in China. They then white-label these chairs with their company name and sell them at a lower price.
Without putting emphasis on where it came from, how does Osaki OS-4000 Massage Chair measure up to other mid-price massage chairs on the market? Is the quality of this chair on par with other popular–and more expensive–massage chairs?
Read on to find out.
Who is it for?
Osaki OS-4000 Massage Chair is one of only a few quality zero gravity massage chairs you can buy for less than $3,000. If you’re looking for the best bang for your buck, this one is definitely a great choice. It has modern style and rich features you normally won’t expect from a cheaper massage chair.
Osaki OS-4000 is long enough to fit users as tall as 6’4″, but not wide enough to accommodate those with broader shoulders. And unlike the Inada Sogno DreamWave, this chair along with other China-made massage chairs have a weight limit. In the case of OS-4000, it can only accommodate people who weigh up to 230 lbs.
Although it resembles Inada’s design, the features of Osaki OS-4000 don’t even come close to that of the former. For instance, the more expensive Inada has massage rollers that can extend all the way down to the buttocks and has a proprietary DreamWave technology that relieves hip and low back pain. Both of these features are not available in Osaka OS-4000.
This massage chair also lacks a built-in music player, mechanical foot rollers, and upper arm airbag massage–features that may play a critical role in your buying decision.
*6 automatic massage programs plus different manual massage modes to choose from including Kneading, Tapping, Rolling, Shiatsu and Swedish.
*Body scan technology that measures your body curvature, size and width to ensure it will deliver precise massage tailor-fit for your needs.
*A 30-inch roller track designed to follow your spine’s natural curvature (S-track design). The quad rollers (i.e., two for each side of the back) enable the chair to massage a wider area of your back.
*Heating pads on each side of the lower back to help release muscle tension and boost blood circulation.
*Zero gravity recline feature allows you to tilt the chair seat to 30 degrees, elevating the thighs at the level of your heart. Inspired by NASA, zero gravity decompresses your back and gives way to a deeper, more relaxing massage experience. Osaki massage chairs have 2-level zero gravity feature, meaning you can recline it further than the standard 30 degrees if you prefer deeper recline.

*38 airbags that provide air compression massage to the shoulders, hips, arms, feet, and calves. Compared to previous batches, the number of airbags in new Osaki OS-4000 massage chairs has been reduced to ensure quiet operation. They are also intelligently designed to make the airbags more durable and efficient.
*The main controller mounted on the side of the massage chair has a large LCD display and a variety of options that can adjust the intensity, speed, and location of the massage. The chair also comes with a wireless remote control so you can easily change the settings even while you’re in a reclined position.
*Spot or Localized Back massage is a button that allows the user to adjust the location of the massage or focus on a specific area of the back.
*Made of synthetic leather to increase durability and comfort.
*Auto leg scan ensures the user will enjoy foot and calf massage that perfectly match the length of the legs.
*Adjustable ottoman length allows the massage chair to fit people as tall as 6’4″.
*Auto-timer setting limits the operation to up to 30 minutes. A cool-down period is required in between to ensure the safety of the user and integrity of the massage chair motors.
*Stretch program which involves the leg portion going up and down, reinvigorating all the muscles, discs and ligaments of the back.
Product Dimensions: 46 x 32 x 47 inches | Weight: 250 pounds
⊕Comes with 3-year product warranty which covers parts costs and labor during the first year, parts costs for the second year and structural framework for the third year. Osaki also has a functional website where you can get additional information about their products, warranty and customer support hotline.
⊕The chair has an adjustable ottoman length which enables it to accommodate taller people who are up to 6’4″ in height.
⊕Although they’re relatively weaker than Inada’s, the neck and shoulder massage in this Osaki chair are good enough. To get a better massage experience, you can remove the pillow and flip it over the back of the chair.
⊕The massage rollers and air bags both have an adjustable intensity, speed, and location.
⊕This chair is covered with synthetic leather which is known in the industry as more durable and easier to clean than genuine leather upholstery.
⊕2-level zero gravity is a unique feature among Osaki massage chairs. In addition to the usual zero gravity position, you can also recline it further if you prefer a much deeper massage experience.
⊗Relatively harder to assemble compared to other massage chairs. This is especially true if you’re not a handyman type and only rely on instructional manual or videos. What makes this even more challenging is the weight of the components–they’re pretty heavy! Attaching the back of the chair with all the bolts that come with it is really difficult. You’ll need another person to complete this task. Assembly time is approximately 30 minutes or less.
⊗The chair is heavy and cumbersome. It comes in two boxes, with a total weight of 300 lbs. or so. If your doorway has a width of 31″ or smaller, there’s very low chance that you can get all boxes inside the house through that door. I suggest paying for a white glove service to make things easier for you.
⊗Osaki OS-4000 has two main controls: the larger main controller which is mounted on the side and the wireless remote control. Some of the buttons on the main controller are not backlit and therefore hard to use in a dark or dimly lit room. The metal stick where it’s mounted is also a bit wobbly.
⊗The back massage is lacking in strength. Even if you remove the softening pad from the backrest, the massage is still weak overall. Perhaps a little more intensity will benefit those who prefer a stronger massage.
⊗Osaki OS-4000 lacks mechanical foot rollers. Foot massage is done only with the help of airbags that provide compression massage. If you’re looking for a similar chair with the foot roller feature, you might want to try the new and upgraded version called Osaki OS-4000T.
⊗No buttocks or glutes massage. This massage chair only offers vibration and air compression massage on the seat and hips. Its massage rollers only run from the neck to just above the tailbone.
⊗Since it doesn’t have a space-saving feature, you’d need to leave at least 16″ to 23″ of free space between the massage chair and wall so it can properly recline.
⊗It’s not designed to accommodate people with broader shoulders, although you can widen it if you’re willing to do some handiwork.
⊗The “SMART” setting, one of the chair’s auto-massage programs, is too vigorous and intense for the feet and calves.
⊗It takes at least 5 minutes before the heat function on the lower back starts working.
⊗The main controller creates distracting beeping sounds throughout the duration of the massage. The noise can last for at least 5 seconds and is designed to remind the user to adjust or change certain settings. The beeping sound is part of the program, and there’s no option for you to turn it off.
⊗Unlike the Inada Sogno that massages the whole arms, Osaki OS-4000 has airbags that provide compression massage only to the forearms and wrists.
⊗Osaki OS-4000 airbags only press against the ITB muscles that run along the side of the thighs. In other massage chairs like Inada Sogno, this muscle group is treated with a wavelike motion that feels like a genuine massage. ITB is responsible for pain in the knees, hips and lower back.
⊗No built-in music player or system. If you want a similar massage chair with this feature, try the Osaki 6000.
The Bottom Line.
Osaki OS-4000 massage chair is every budget buyer’s dream come true. With a modern look and outstanding list of features, this massage chair gives the best bang for your buck. However, you have to understand that a product this affordable has certain limitations. For instance, it doesn’t have mechanical foot rollers and also not capable of massaging the buttocks.
Overall, Osaki OS-4000 has proven with great success that quality and affordability can coexist in one product. Although it’s not at the same level as Inada, the Osaki OS-4000 provides people with limited budget an opportunity to own a good massage chair that will last for many years.
