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 following sections, 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.

Key Features of the Cozzia EC366 Massage Chair

Before discussing the features, we should note that this model is listed in several ways. You may see it referenced as the EC 366B or 366C, and if you do, be aware that these are 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.

S-Track Design / Quad Rollers

As with most massage chairs produced today, 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, guaranteeing a great massage experience.

3D Body Scan

Working in tandem with the abovementioned features, this model also features 3D Body Scan Technology. This automated protocol locates your body’s pressure points and makes subtle adjustments to the position of the rollers to ensure they hit all your pressure points.

If the tech gets it wrong, the remote has buttons that allow manual fine-tuning of 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

We were impressed with the number of options for an entry-level chair. As far as massage techniques go, these include:

We’ve seen some references to this chair having a Swedish massage function, but we can confirm this is untrue.

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 be pre-programmed routines. These are:

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

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. After checking the manual, we confirmed that there are, in fact, 30 airbags. These are second-generation airbags, but 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 neck, head, or shoulder airbags. Even so, you get airbags located in the:

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

This feature is fairly comprehensive. It’s just inaccurate to describe it as a full-body air massage. The interesting thing about this feature is that you can activate only the zones you want or all of them. You can also control intensity on a zone-by-zone basis through levels, just like 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, but as with most budget-priced chairs, the heat is binary. You can turn it on or off but cannot 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 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 benefits 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 the spine.

While it may offer some therapeutic benefit to people with 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 acceptable, but a chair with foot rollers would likely serve you better if you spend several hours daily on your feet.

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

Other models on the market offer an airbag-only calf and foot massage, but the EC 366 is the first one that separates the controls for calf and foot. It’s a minor point, but it’s worth nothing.

Spot Massage Mode

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

Fairly Simple Remote

Cozzia EC366 Massage Chair Remote - Chair Institute

It’s not that the chair is hard to use—it isn’t—but the remote isn’t as organized as we’ve seen in other Cozzia massage chairs, and the buttons seem misplaced.

It doesn’t seem like the company put much thought into the layout, and while it won’t take long to master all the features of this chair, in some ways, the remote feels like it 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 features were poorly implemented, resulting in a good chair that fell short of 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. In our view, rollers are almost necessary to provide maximum benefit to people suffering from chronic leg and foot pain.
  • No calf heat – Again, it’s clear that the designers considered therapeutic benefits, and adding heat to the leg massage ports would be a huge win.
  • A full-body stretch – While 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 greatly increase the design’s overall effectiveness.

Special note: We’ve seen reports that the EC 366 features an adjustable Ottoman. However, the user manual does not mention this; 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 great. Consider the features on offer carefully and compare them to your 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.), other models would be a better fit.
