Osaki OS-4000 Zero Gravity Massage Chair Review [Sep. 2021]

Before you start reading, be aware that OS-4000T is a newer model that comes with the foot rollers. The older model is still available from various online retailers, so make sure you are getting the right model.

Foot rollers are the main difference. The 4000T model is slowly replacing the original model. Foot rollers are a fantastic addition, especially for people involved in any sport, including running, tennis, biking, etc.

Also be aware of 2 additional models in the same line: 4000cs and 4000ls. They include L-Track Technology (rollers extend from the neck into the seat to give a massage to the glute muscles for a full body massage).

Also, they include adjustable shoulder airbags which were an issue in the original model, deeper massage programs, and space-saving technology)

Balancing life to have an equal amount of business and pleasure is like juggling two sharp knives on both hands while standing on a thin narrow beam.

It is hard, but it is attainable.

Just investing an ample amount of time, quality, and money on the things that matter the most is the key.

Besides, all of us deserve some rest after a long and hard day at work (unless you work from home, but you need to relax after sitting all day long, right?).

Osaki OS-4000 Executive will provide just that; or not?

Let's find out more about the 4000 model and see if it can provide all of the whistles and features it claims to have and if it's the best massage chair for the price.

True Ergonomic S-Track Design

The 4000 chairs is ergonomically designed to adjust to a variety of spine shapes.

Each person has unique Spine curvature.

The S-track allows rollers to provide a massage along from the neck down to the lower spine with consistent pressure.

Many cheaper manufacturers have tracks that are linear which creates inconsistent pressure which will provide weak massages in the lower back and neck area.

Computer Body Scan System

The latest technology allows rollers to follow the exact and precise map of the back curvature, which in turn helps to precisely hit all the key areas.

Regardless of your body type, this technology will adjust itself making each movement unique just to your body.

Next Generation Air Massage Technology

The airbags have been engineered in a way that it reduces the number of airbags but increases the surface coverage.

This way chair is consuming less power which makes it less noisy with the reduction of valves and air pumps, allowing for a more quiet and tranquil experience.

The material that Osaki / Titan uses to create the airbags is industrial-grade material that is durable and provides comfort at the same time.

Trust Factor

The dedication, value, and overall perspective they put on every Osaki Massage Chair lead the company to be the World’s Ultimate Massage Chair manufacturer and one of the Nation’s Largest Distributors.

Quick Note: I’ve been on phone with them a few times and their support is the best I’ve seen in the industry

Full Body Massage Experience

The Osaki 4000 Executive Zero Gravity Chair is all you need to have.

Invented with a set of S-track movable intelligent robots to release the tension off your body with the use of twin rollers.

Gliding like a human thumb from your neck, through your shoulder, the entire back area, and down to your buttocks then thigh, calves, and all the way to your feet while gently vibrating your seat with a lower back heat therapy.

There is nothing like an Osaki 4000 massage chair experience.

NOTE: This chair provides medium intensity massage, so if you are looking for a deep tissue massage experience, make sure you buy a different model.

Health Benefits

The Zero Gravity design allows you to fully stretch out your back in the most accurate position that feels like you’re floating in the air that helps release the muscle tension to get rid of all those exhaustion we get from the day-to-day job, slowly fix the spine’s contour and improves blood circulation.

The Osaki 4000 is equipped with a total of 32 airbags strategically placed to provide full-body relaxation.

Warranty

The chair comes with a 1-year warranty + TWO-year additional parts factory warranty. You can get a 1 or 2 years extended plan for parts and labor which we highly recommend doing.

Many people opt-in for White glove delivery (around $250), but installation instructions are also available.

Innovative Technology

You can choose from the following six unique auto-programs: Healthcare, Relax, Therapy, Smart, Circulation, and Demo by just simply using the easy-to-follow wireless mini-controller.

It also has three kinds of width adjustable settings that can be Wide, Medium, or Narrow.

The Osaki 4000 offers six massage styles with five levels of speed and intensity namely rolling, kneading, clapping, shiatsu, Swedish, and combo to suits your moods and preferences.

You don’t have to worry about not fitting because of its design that automatically makes micro-adjustments to bend along to support your entire back.

Your calf and foot massager has the same capability to make the necessary adjustments as well.

Value for Money

The Osaki 4000 Executive Zero Gravity Chair costs is under $3000.

It may be pricey compared to some no-name Chinese chairs.

But considering brand name and benefits and features provided, investing in 4000 will be a wise choice instead of settling for a cheap and poor-quality made type that may cause even more back pain instead of a relief (many such stories we came across while researching for this review)

Also it comes with four different and very stylish color combinations:

Charcoal/Beige
Burgundy/Black
Cream/Beige
Black/Beige

Customers Feedback on Osaki os-4000

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 session that just meets your needs.
“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.
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!”
“A little pricey but in this case you get what you pay for. Very nice, full body 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.”

Quick video Review:

Are Massage Chairs Worth Buying?

If you're into relaxing and finding new ways to move your body, you might be wondering what kinds of models are available in the market today. After all, if you're looking to spend some cash on your post-workout recovery, you'll probably want the right chair that allows you to lay down and get your back and neck worked out.

Well, let me tell you — there are many different kinds of models, and no two are exactly alike. While there are a few technologies common among all these chairs, like vibration technology or temperature control, the experience can vary tremendously depending on your chair, the skill of the massage therapist, and what kinds of adjustments you make on the chair. You want to make sure that you're getting the right kind of massage," said Dr. Uchenna Obiora, a chiropractor in Glendale, California, and co-owner of Triceps U. The bad news is that different types of massages require different kinds of equipment, and not all models have the same massage capacity.
