Features of the Osaki OS-4000

The Osaki OS-4000 is Osaki’s mid-range model, positioning between the top-end 7200 and the introductory OS-1000 models. For a mid-range model, however, it has a truly impressive range of different options.

46 Air Bags

The number of air bags in a given massage chair is normally a sign of it’s level of quality. The more air bags a massage chair has, the more control you have over the massage, and the more “reliastic” the overall effect. In short, more air bags = better quality of massage.

The Osaki OS-4000 boasts an impressive 46 air bags – well above the average seen in the industry. This means that the 4000 can reach places that other massage chairs cannot; ideal if you’ve tried competing massage chairs in the past but been underwhelmed by their effects.

6 Preset Programs

Pre-set programs allow you to get started with your massage as easily as possible. Simply select one of the preset modes and off you go. In the case of the Osaki OS-4000, the program options are:

  • Healthcare
  • Relax
  • Therapy
  • Smart
  • Circulation
  • Demo

5 Intensity Levels

As well as these 6 preset programs, the OS-4000 also boasts 5 different levels of speed and intensity. Combined with the 6 preset programs, this creates dozens of possible combinations, perfect for finding your perfect massage program.

For the purposes of the Osaki 4000 these options are:

  • Rolling
  • Kneading
  • Clapping
  • Shiatsu
  • Swedish

Full Body Massage

It is difficult to describe exactly what it feels like the first time you sit in the Osaki OS-4000.

For want of a better way to describe the experience, you “sink into” the chair, and it gives a pleasant feeling of being surrounded on all sides – rather like being curled up in your comforter. This immediately creates a feeling of comfort, privacy and luxury.

This “cocoon” though isn’t just for stylistic purposes; it also has a very practical purpose. The 46 air bags are carefully distributed throughout the chair ready to pleasantly knead the feet, calves, back, shoulders, neck and hips.

This means that the Osaki OS-4000 offers what few other chairs really do – an opportunity to have your entire body massaged rather than just your back for a more thorough massage experience and better pain relief.

Auto Detect Massaging

The OS-4000 is the first model in the Osaki range to offer what they call “smart auto detect” massaging. What this means is that the chair is capable of detecting the curvature of your spine and then making adjustments to the massage programs in response to your body.

This not only makes massage from the 4000 a far comfortable proposition, but it also ensures the chair gets into all those important places, providing far higher quality of massage as a result. Quite simply it’s a chair that responds to your unique body shape and pose.

Incredible Level of Control

When you combine all of these different features together it becomes clear just how many options there are for creating your perfect massage All of these options and more are controlled through the simple LCD controller. The following video does a good job of demonstrating just how much control you have when using the Osaki OS-4000:

Lower Back Heating

When it comes to using a massage chair to relieve lower back pain, a feature which can really help to produce rapid results is warmth. Here the Osaki OS-4000 comes up trumps, offering the option of a heated lumbar/lower back area. This serves to help relax the muscles and joints, not to mention increasing blood flow to the area and so reducing discomfort swiftly.

160 Degree Recline

The Osaki Os-4000, like all the best massage chairs, is a recliner. This allows you to lie back while enjoying your massage, creating not only more “authentic” massage experience, but also allowing the chair to provide you an all-over massage rather than having to focus on a smaller part of your body.

A 160 recline means you will be almost horizontal when the chair reclines. “Why not totally flat?” you might ask. The simple answer is that for massage purposes you are generally best-positioned when reclined gently but not lying flat as a board. This helps to remove pressure from the joints, as well as the posterior and shoulders. Furthermore, it prevents the small of the back from drooping, which can make pain worse rather than better.

Osaki OS-4000 Reviews

The following independent reviews from owners of Osaki OS-4000 are taken from Amazon, and show some of the recent comments made by people who have tried the OS-4000 out in person:

Review #1

“After some trial and error, settled to use Healthcare with intensity and speed of 4 that seem to knock out the pain points around the muscles in neck area of spine. I do it several times a week, sometimes just for 15 min and occasionally for 30 minutes. Rest of my family mostly use ‘Relax’ mode and once they get more comfortable might try out other options. The point is you have a massage that just meets your needs.”

Review #2

“This product is great! In terms of what it has to offer, it probably tops any of the chairs you’ll see in the mall and also does it at half the cost, although IMO these things are already overpriced. There is a warning not to use the chair for more than 30 mins due to overheating.

Review #3

There is an annoying timer, which will shut off the chair, but you can always add time, and I’ve used it for more than 30 mins no problem. Also the chair is prone to electric surges, so make sure to connect it to a good surge protector (or just unplug it when not in use). The only real cons are the size and the overly powerful calf massagers, but if you think you can fit and if your wallet can afford it, buy this chair!”

Review #4

“A little pricey but in this case you get what you pay for. Very nice, full body massage chair that looks great and is well constructed. I love the arm massage which of course you don’t find in most chairs out there.”

Osaki OS-4000 Specifications

The Osaki OS-4000, like all premium chairs, weighs a considerable amount. This shouldn’t be seen as a negative aspect; indeed the simple reason for this weight is simply how well-built the chair really is. With all the the technology built in – from air cushions to computerized controllers – the weight should be seen as sign of reliability. That said, ordering online or via mail order is going to be preferable than trying to bring home this sizeable and heavy item yourself.
