A modestly priced chair with a surprising range of features. While not for everyone, for the right user, the Cozzia EC366 Massage Chair would make for an excellent chair. Recommended for hobbyist users, people who suffer from lower back pain and not taller than 6’3”.

Are you on a budget?

Looking for a massage chair with hard-hitting therapeutic benefits that won’t break the bank?

If you answered yes to either of those questions, then the Cozzia EC366 massage chair might be exactly what you’ve been looking for.

In the sections that follow, we’ll outline exactly what this chair is, and isn’t. It’s not perfect, and it’s not for everyone, but it’s got enough capability to make it interesting, and it just may have the perfect combination of features for you.

Overview of the Cozzia EC366 Massage Chair

Before we jump into the features, we should note that we have found this model listed in a few different ways. You may see it referenced as the EC 366B or 366C, and if you do, be aware that these are all identical in every way. We’ve checked the manufacturer’s site, and there are no variants for this model, a fact borne out by the user manual.

Cozzia EC366 Massage Chair Features

S-Track Design / Quad Rollers

As with most massage chairs produced these days, the EC 366 is built around a standard S-Track which allows its quad rollers to follow the natural curve of your body’s spine, which guarantees a great massage experience.

3D Body Scan

Working in tandem with the features mentioned above, this model also features 3D Body Scan Technology, which is an automated protocol that locates your body’s pressure points and makes subtle adjustments to the position of the rollers to make sure they’re hitting all your pressure points.

If the tech gets it wrong, there are also buttons on the remote allowing for manual fine tuning of both the roller positions and the width of the massage field.

No Zero-Gravity Seating

We’ve seen some confusion about the number of Zero-G seating options available on other Cozzia EC366 massage chair reviews, with some sites reporting 1, and other sites reporting two seating positions.

Having researched the matter, we can confirm that this model does not offer Zero-Gravity seating.

More Options Than You Might Expect

For an entry-level chair, we were impressed with the number of options it had. As far as massage techniques go, these include:

Note that we’ve seen some references to this chair having a Swedish massage function, but we can confirm that this is not the case.

In addition to these, the model also offers a total of four pre-programmed massage options, which are:

  • Healthcare
  • Relax
  • Smart
  • Spa

Finally, the chair offers two partial massage modes, which could technically count as pre-programmed routines. These are:

All of these may be adjusted via the remote through four levels of intensity. This is a win for the chair because the industry standard is three intensity levels. It’s a bit of a surprise to find more than that on a chair with such a low price!

Air Massage Mode

Again, we have found some conflicting reports in other Cozzia EC 366 massage chair reviews on the web, with some sites reporting that this chair had 44 airbags.

That would be a tremendous number for a budget-priced chair, which made us suspicious. Checking with the manual, we have confirmed that there are in fact 30 airbags. Note that these are Second Generation airbags, and thirty is still an amazing number for such a low-priced chair.

It should be noted, however, that the user manual incorrectly refers to their air massage as “full body.” It is not, because there are no airbags for the neck, head or shoulders. Even so, you get airbags located in the:

  • Arms
  • Back/Seat/Hips
  • Calves
  • And Feet

Which is fairly comprehensive. It’s just inaccurate to describe it as a full body air massage. The interesting thing about this feature is the fact that you can activate only the zones you want, or, activate them all. You can also control intensity on a zone-by-zone basis through for levels, just like you can with the roller-based massage.

Normally, on low-priced chairs, the air massage function is binary, which makes this an unexpected perk.

Lumbar Heat

The EC 366 offers lumbar heat, and as with most budget-priced chairs, the heat is binary. You can turn it on, or leave it off, but you are unable to control the precise temperature.

Even so, if you suffer from chronic lower back pain, this is almost guaranteed to be your favorite aspect of the chair.

Adjustable Timer

All the massage programs offered by the chair default to a duration of fifteen minutes. This can be adjusted up or down in five-minute increments to a minimum of five minutes, and a maximum of thirty minutes.

Leg Stretch

While the EC 366 doesn’t provide a full body stretch, it does have a nice leg stretch feature. This offers some therapeutic benefit to those who suffer from chronic leg pain, but it would be a mistake to think that this feature is comparable to a chiropractic adjustment to your spine.

While it may offer some therapeutic benefit to people who suffer from chronic back pain, you would be better served to find a chair with a full body stretch function.

Foot And/Or Calf Massage

We regard this as a weakness in this model’s design because there are no foot rollers to render a massage to the soles of the feet. The chair uses airbags for the foot massage, rendering it by gently squeezing and releasing your feet.

The result is certainly acceptable, but if you spend several hours a day on your feet, then a chair with foot rollers would likely serve you better.

One interesting twist about the way Cozzia implemented this feature is that the calf and foot airbags can be independently controlled.

There are other models on the market that offer an airbag only calf and foot massage, but the EC 366 is the first one we’ve seen that separates the controls for calf and foot. It’s a minor point, but worth nothing.

Spot Massage Mode

This is a great addition to the model. If during the course of your massage, the rollers hit a particularly tender spot, you can hit the “spot” button, and it will interrupt whatever massage program is running, and focus on the area within a six-inch diameter, measured from the location of the rollers when you pressed the button.

Fairly Simple Remote

Cozzia EC366 Massage Chair Remote - Chair Institute

It’s not that the chair ‘s hard to use – it isn’t, but the remote isn’t laid out in as organized a fashion as we’ve seen in other Cozzia designs, and the buttons seem misplaced.

It doesn’t seem like the company put much thought into the layout, and while it won’t take you long to master all the features of this chair, in some ways, it feels like the remote is working against you.

Pros & Cons of the Cozzia EC366 Massage Chair

In many ways, this is an unusual model. It certainly gets the basics right, but in our view, some of the features were poorly implemented, resulting in a chair that’s good, but falls short of being great. In our opinion, here’s where the Cozzia EC366 comes up short:

  • No foot rollers – This was a real disappointment, especially given that the stretch function only covers the legs. To provide maximum benefit to people who suffer from chronic leg and foot pain, rollers are almost a necessity, in our view.
  • No calf heat – Again, it’s clear that the designers had therapeutic benefits in mind, and adding heat to the leg massage ports would be a huge win.
  • A full body stretch – While having a leg stretch function is certainly helpful, a full body stretch would have been much better.

All these features exist in some form in the chair already, so these are not huge changes, but they would increase the overall effectiveness of the design tremendously.

Special note: We’ve seen it reported that the EC 366 features an adjustable Ottoman. The user manual makes no mention of this, and the chair is only designed to accommodate users up to 6’3” in height.

Cozzia EC366 Massage Chair Conclusion

This is not a bad chair, but it’s also not a great one. Consider the features on offer carefully, and measure them against your specific needs.

For the right user, the EC 366 offers tremendous value for the money, but if you have a particular need (body stretch, chronic foot pain, etc.), then there are other models that would be a better fit for you.
