Osaki OS-4000 Massage Chair Review

Deciding upon the perfect anti-gravity massage chair can be a real task.

You have to consider your personal health needs, your living space availability, and of course your budget. But if the latter isn’t so much of an issue, chances are you have plenty of living space for a top of the line model which addresses the even trickiest health issues.

The 3d zero-gravity massage chairs are the best on the market, but there are several brands from which to choose. Each brand has their own top models. So how do you choose?

The answer’s pretty simple. You let previous customers help. One of the top brands to date is Osaki. And the top model of 2020 was the Osaki OS-4000.

But just why is it so popular?

Compelling Features of the Osaki OS-4000 Massage Chair

Like all 3d top model massagers, the Osaki OS–4000 offers a zero gravity reclining mode. This is the position made popular by NASA astronauts. The body is reclined to the point where the feet are at the same level as the heart.

It creates a feeling of weightlessness which in turn reduces physical stress felt by the body. As this stress is released, oxygen intake improves, bodily functions adjust as needed, and overall healing occurs.

Airbags are essential to any quality massage chair. However, there has been a lot of confusion regarding how many air bags are actually present in this model.

Some accounts state 25. Major sites like Amazon claim there are 32 airbags. Both accounts are way off base.

According the Osaki customer service, the Osaki OS–4000 massage chair contains 48 air bags: 14 in the foot compartment, 10 for the calves/legs, 6 in the seat, 6 in the hip area, 8 for the arms, 2 in the shoulder area, and another 2 for the neck or head.

The number and placement of airbags is an important consideration when choosing the perfect chair as the airbags mimic the human motions of trained professional massage therapists.

Even if finances aren’t a concern, when you purchase high end equipment such as a 3d massage chair, you expect it to work on a professional level… or at least be as close to professional care as possible.

The Osaki OS–4000 doesn’t disappoint. Along with the airbags, it contains a 30-inch roller stroke which extends from the neck down to the lower back. That’s where most of your body tension will likely reside.

And that’s precisely where most professional massage therapists spend the majority of their time. The roller works with the bags to loosen those knots you’ve had for years, as well as correct any new ones that may have decided to visit.

Massage Benefits of the Osaki OS–4000

Six massage types let you mix and match until you find the perfect massage for each part of your body. Choose between shiatsu, Swedish, clapping, kneading, rolling, and combo options.

Five speed settings and five intensity settings can make the most of any massage, whether you choose a 5 minute quickie to full 30 minute manual session, or opt for a standard 20 minute auto session. The vibration seat massage option is great for getting some much needed blood pumping the rump.

That’s especially helpful for those who live a relatively sedentary lifestyle, regardless of choice or necessity. If your back is in need of serious attention, choose the back heater option.

The heat relaxes tight muscles even further and allows more benefits to be achieved by whichever massage you choose. A simple-to-use remote allows you to make or change your program decisions at the touch of a button.

Body scan technology is a favorite massage feature among Osaki fans. Everyone is built differently, and a prime concern when shopping for this type of equipment is that your specific body will somehow not fit correctly or be tended to properly. That’s not an issue with the OS-4000.

The chair scans your body and instantly adjusts the air bags and rollers to fit your specific needs. If someone else uses the chair after you, it can adjust for them as well… and so on, and so forth. This is not your typical recliner.

Confused about which massage you really need? Don’t be. Osaki’s S-Track Intelligent Massage Robot works alongside the body scan technology to adjust to your specific body requirements.

The massage robot takes the information provided by the body scan and creates a specific massage based on your own body’s stress readouts. That means if you’re carrying more tension around your shoulders, it focuses there. If your hips are tight or your back is about to enter spasm mode, it works on those areas.

All you have to do is lie back and let the magic happen. And if something’s too strong or doesn’t feel quite right, just adjust the settings on the wireless remote until you’re happy with the strength.

The Pro Dreamer leads the pack for the Pro Series options. But how do the Pro Dreamer and 4000 differ? First of all, they’re both amazing chairs and you can’t go wrong with either one. But the Pro Dreamer has a lot of extra features. And it should since it’s basically the Cadillac massage chair version for Osaki.

The Pro Dreamer contains 65 air bags and 13 motors as opposed to 48 and 11 for the 4000. Foot rollers are an extra bonus on the PD as well. Those aid people who stand on their feet all day or need a deep sole massage. Instead of 5 speed and intensity settings, the Pro Dreamer offers 10 each.

And while the weight capacity for the 4000 is 250, the Pro Dreamer allows up to 265 pound individual usage weight.

But that’s not where the differences end. The Pro Dreamer is considered the top 3d choice for music lovers. This is due to the MP3/bluetooth musical option available during massage mode.

Simply download apps to your mobile device and upload them to the chair’s computer. Two built-in speakers at head level allow you to experience music therapy as you get the massage of your life.

Chromotherapy is also an option with the Pro Dreamer. As the room lights are lowered, two lights on the side of the chair give an ambiance glow that aids in extreme relaxation.

However, even with all the bells and whistles, one of the biggest comparisons is the price. No top of the line 3d massage chair can be considered inexpensive. These are luxury purchases, no doubt about it. However, the OS-4000 is one of the most reasonably priced models in its class. The Osaki 3d Pro Dreamer can easily cost 2 to 3 times that of the 4000.

If you’re looking for a top of the line model that has enough bells and whistles to be in league with models far more expensive, the OS–4000 deserves your attention.

Being an Osaki, it has one of the best warranties in the industry at 3 years of coverage regardless of what happens to it. Because the last thing you want to have is a gorgeous and expensive machine that doesn’t work. This warranty also covers commercial use.

Yes, the OS–4000 can be used in a business setting without voiding the warranty. That’s a major bonus on its own for professionals and their clients. But only you can decide upon whether the 4000 or her sister, the OS-3D Pro, fit your needs.

Regardless, both are reckoning forces. And since they’re Osaki’s, you can expect years of pure enjoyment.
