In a Nutshell:

The Kyota M673 Kenko massage chair is a very good model that falls just shy of excellence in our view. Everything about this chair is well implemented, but there are no standout, must-have features here. It is recommended for anyone weighing up to 300 pounds looking for a good, well-rounded design with no specific need in mind.

Are you in the market for a good-quality massage chair? Are you overwhelmed by the sheer number of choices on the market? If so, you’ll like what you read in this—our Kyota M673 Kenko massage chair review.

Have you never heard of Kyota? 

If you haven’t, you’re not alone. But no worries, Kyota is to Infinity what Titan is to Osaki, which is to say that the Kyota brand is a subsidiary of Infinity, which, while not one of the biggest players, is nonetheless a well-known and well-respected brand in the massage chair industry. Massage chairs by Kyota are pretty solid.

As you’ll see in this review, we don’t love this chair, but we do like it very much. While nothing here, in particular, stands out as a “must-have” element, every feature the Kyota Kenko brings to the table is competently implemented and has a lot to offer.  

All that to say, if you’re not looking for one thing in particular but just want a good, well-rounded chair, this one may be perfect for you.

In the sections that follow, we’ll step you through everything it has to offer, and by the time you reach the end, we think you’ll agree. This chair may not rise to the level of greatness, but it is an exceptionally solid, well-rounded design, and there’s something to be said for that. 

Let’s take a closer look.

An Overview Of The Kyota M673 Kenko Massage Chair

It’s clear that the Kenko’s design team wasn’t interested in taking any chances where aesthetics were concerned. They designed their chair along purely conventional lines, so it looks like the vast majority of the other massage chair options available today.

That’s not a bad thing, but it does mean that the Kyota Kenko M673 has a kind of futuristic look to it, and unless that’s the prevailing décor scheme in your house, it’s going to stand out in whatever room you place it in.

On the other hand, most people who are in the market for a massage chair care a lot more about what it can do and not nearly as much about what it looks like, and this model certainly isn’t ugly. So if you’re more interested in function over form, then you probably won’t have an issue with the look of the thing at all.

One thing that might give you pause, however, is its size. Although it’s not all that wide, this is a big piece of furniture, with a footprint that measures 62” L x 29” W x 48.5” H when upright and 72” L x 29” W x 38” H when fully reclined.  

It also weighs 292 pounds, so this isn’t something you’re just going to be able to lift up and tote through your house to whatever room you want it in.

Your best bet is to arrange for at least one extra pair of hands when the chair arrives or pay an additional fee for White Glove service to let someone else worry about wrestling it into position.

Note too that given the size, if you have smaller rooms in your home, finding a place to put this beast can be a challenge, though the chair is designed with space-saving technology, so you only need about 4” of space between the seatback and whatever wall you place it near, and that definitely helps.

The last thing to mention before leaving this section is that the Kyota M673 Kenko can accommodate users ranging in height from 4’10” to 6’4” and weighing up to 300 pounds, which describes the vast majority of the market. If you happen to weigh more than that, though, the weight limit will be an absolute deal-breaker, unfortunately.

The Kenko Massage Chair Has Good Bones

This is something we don’t think other Kyota Kenko M673 3D massage chair by Infinity reviews pay enough attention to, but it’s really important, in our opinion. After all, if the foundation of the chair in question isn’t rock solid, how good can the rest of the design actually be?

In the case of the Kenko, there’s nothing at all to worry about. This chair features a delightful, 49” long L-shaped massage track that starts near the top of the seatback, travels down its full length, then turns and continues under the seat, allowing the quad rollers attached to the track to massage your glutes and the backs of your thighs.

Even better, this is a 3D massage track, so the rollers can move along the X-, Y-, and the Z-axis, meaning that the Kenko is capable of rendering a true deep tissue massage, which is the first of a few different therapeutic features we’ll be talking about.

There’s more. Kyota bills this model as a 4D chair, and they’re using the term to describe the fact that as the rollers massage various parts of your body, the speed and intensity will change dynamically, depending on exactly where the rollers are, which more closely replicates the feel of human hands on your back. That’s superb.

On top of that, the Kenko sports “Truefit” body scanning technology, which is used to dynamically adjust the position of the rollers before your massage begins in a bid to ensure that the rollers are hitting your body’s pressure points.  

This works more than 95% of the time, and when it fails, you’ll find controls on the included remote that allow you to manually tweak the rollers’ position.

This combination of features makes it virtually impossible for you to get a substandard massage from the chair, which is very nice indeed and one less thing to have to think about or worry over.

The Kyota Kenko M673 3D Massage Chair By Infinity Boasts An Average Number of Options

We began by saying that from pretty much top to bottom, this was a competently designed chair, but there were no real standout features. This is a classic case in point. It’s not hard to find comparably priced chairs with more to offer in this section, and it’s not hard to find comparably priced chairs that don’t offer as much, putting the Kenko squarely in the middle of the pack.

In terms of massage techniques on offer, you’ll find:

  • Kneading
  • Tapping
  • Kneading + Tapping
  • Knocking
  • Shiatsu

The chair also offers a music sync feature, which sets the rollers to the beat of whatever music you’re listening to. Most massage chairs that offer this feature list it as a technique. That’s not the case here, but essentially, that gives this model one additional technique.

In addition to that, you’ll find the following pre-programmed massage routines available on the Kyota Kenko M673 3D chair:

  • Sports Refresh
  • Extension
  • Rest & Sleep
  • Working Relief
  • Neck and Shoulder
  • Waist and Spine
  • Deep Shiatsu
  • Healthy Breath
  • Massage Extend
  • All Air

Ten different routines in all. Not bad, and they give you a fantastic cross-section to draw from, so there’s something here for just about everyone.  

It’s well worth trying them all and experimenting with. Still, the two most noteworthy, in our view, are the Deep Shiatsu routine—which you’ll probably be interested in if you’re really craving an incredibly deep tissue massage—and the “Extension” routine, which is the Kenko’s version of body stretching.

Although Infinity/Kyota doesn’t have the best body stretch in the industry, this one’s quite good and is a second therapeutic feature that the Kenko brings to the table.

In addition to that, you’ll find both spot and partial massage modes available, along with six different speed settings and five different roller intensity settings.

All in all, that gives you a ton of different ways to tweak and customize the massages you get from this chair, which is awesome and right in line with what we expect to see for a chair offered at this price point.

Three-Stage Zero-G Seating!

We’ve seen a number of Kyota Kenko M673 reviews really sing the praises of this feature and its implementation in this model, and we readily agree. This is a nice addition to the feature set, and Zero-G seating is often underappreciated.

It is both a powerful therapeutic feature in its own right, and it helps improve the massage you get from this chair in general.

On its own, in addition to leaving the user feeling weightless while sitting in the chair, it helps to lower blood pressure, improves circulation, and can even help with post-surgical healing.

As a helper feature, when you’re in one of the Zero-G seating positions, your own body weight is pressing you more firmly against the seatback, which means that indirectly, you’re pressing more firmly against the rollers, resulting in an even deeper massage. 

Try it out for yourself—you’ll love the results!

Kyota M673 Kenko 3D Massage Chair Offers Lumbar Heat

This is another average to strong component of our Kyota M673 Kenko massage chair review. As with most everything about this chair, the offered heat is competently implemented but doesn’t really stand out from the pack.

The offered heat is generated by two coils located in the seatback. Although billed as lumbar heat, it actually radiates well into the midback, which is why we’ll rate it slightly above average.

Massage always feels great, but massage plus heat takes things to the next level and gives this chair yet another good therapeutic feature to talk about. It’s easy enough to find comparably priced chairs that offer better heat, but plenty of comparably priced chairs don’t offer heat at all!

A Solid But, Again, Unexceptional Airbag-Based massage

The Kyota Kenko M673 3D massage chair sports 22 airbags and a total of 40 air cells, which is about average for a chair in its price range, or perhaps just a shade on the low side.

The Kenko makes good use of those and renders a quite good airbag-based massage that you can customize via the remote, selecting from five different intensity levels.

In addition to that, if you don’t want to activate all of the airbags, you can selectively activate them by the following body regions:

  • Arms and Shoulders
  • Legs and Feet

That’s excellent fine-grained control!

While it’s doubtful that many—if any—people will buy the Kenko on the strength of the airbag massage alone, it’s an excellent addition to the overall feature set, and you won’t be disappointed.

The Kyota Kenko M673 Massage Chair Has A Good Calf And Foot Massage Too

Once again, this is a competently implemented feature, but not one that really stands out.

Most of the massage chairs that offer a calf and foot massage utilize airbags to massage your calves and rollers for the soles of your feet. That’s exactly what the Kenko does. To the chair’s credit, though, you’ll find triple reflexology rollers at the bottom of the footwells, making it slightly better than average.

This is another good, solid feature, and if you have chronically sore feet or legs, it will probably be one of your favorites.

It’s Even Got A Couple Of Extras!

Subsidiary brands often cut corners where extras are concerned, and sure enough, you won’t find many here, but the two that are included are quite good and of high value.

First, note that there are Bluetooth speakers built into the chair. Sync your phone to the speakers and pick your favorite music, and you’ll be able to make use of the “Music Sync” technique we talked briefly about earlier in this review.

The second extra is the presence of a massage timer. All of the massage options on this chair default to 20 minutes, but via the timer, you can change that to either 10 or 30 at your preference. Good stuff.

Pros & Cons of Kyota M673 Kenko Massage Chair

There’s really nothing wrong with this chair. Everything is very consistently well implemented, and it supports a good amount of user weight.

On the other hand, this chair doesn’t have any wow factor. There’s no one feature you can look at and say, “Okay, that’s cool. I must buy this chair in particular to have that.”

No. You really mustn’t. This chair doesn’t have anything like that. What it does offer you, though, is a really well-designed platform with lots of good, well-implemented capabilities, and there’s certainly value in that.

Kyota M673 Kenko Massage Chair Review Conclusion

Although we don’t love this chair, we do like it very much and will absolutely recommend it to anyone weighing up to 300 pounds, provided that you didn’t need an excellent implementation of some particular feature or another.

For instance, if you want a good general-purpose massage chair but you absolutely need something that can give you a world-class body stretch, this isn’t that chair. 

It can give you a body stretch, and it’s good enough to have real therapeutic value, but it’s not best in class for that feature.

So if you’re looking for a good general-purpose massage chair with well-implemented features, yep. 

This is your guy, or at the very least, this one belongs on your shortlist of options to consider.

Other Options To Consider

If you’ve read to the end of this Kyota M673 Kenko massage chair review and it just isn’t a good fit for you, whatever the reason, here are a couple of other models you may want to check out:

Kahuna SM-7300 Massage Chair

Recommended For: Anyone, especially big and tall users.

Check Latest Price Read Detailed Review

Offering a slight increase in supported user weight and the best body stretch in the industry, this is a good choice if you’re just outside the Kenko’s weight limit and you really want the best body stretch you can get your hands on. Kahuna is one of the most respected names in the industry, and this is a superb chair.

Osaki Paragon 4D Massage Chair

Recommended For: Anyone weighing up to 280 pounds, especially if you can find this model on sale (which is fairly often!). The sale price approaches a 50% discount, making the Paragon an insanely good value.

Check Latest Price

The Paragon is a wonder, but there’s a catch. Don’t get this model unless it’s on sale. If you pay full price, it only offers about average value, but it’s frequently found on sale, and if you can get it at a discount, then it becomes one of the best values on the massage chair market today. It’s amazing and well worth a look.
