Mail Bag: DreamWave vs. MA73; chair for 6’4″ & 200 lbs.


Customer Question #1

I had a friend, who lives in Salt Lake City, visit your store this summer and he evaluated and recommended the Panasonic MA73 and Inada DreamWave massage chairs. Would you recommend one over the other for reliability, form or function?
I am in my 60’s and long ago realized you usually get what you pay for so buy once and buy right.

Thank you.

Hi, Mike
The DreamWave and MA73 are pretty equal as far as quality goes. Each has different features, pros and cons. Here are some things to consider:

1. Rollers are more vigorous on the MA73.
2. Heated rollers on the MA73, low back heating element in the DreamWave.
3. The MA73 has shoulder airbags, the DreamWave has upper arm airbags.
4. The Inada has the dreamwave technology where the seat moves from side to side and up and down, while the thigh airbags are inflating to massage the

Panasonic MA73 massage chair
Panasonic MA73

IlioTibial Bands and the rollers are hitting the low back. The MA73 does not have this feature, although it does have thigh airbags and a good low back roller massage.
5. The DreamWave has 100 airbags vs. 33 airbags in the MA73.
6. Stretch program is superior in the DreamWave (IMHO).
7. Arm airbag massage is superior in the MA73 (IMHO).
8. The DreamWave has the cervical traction device, which is a fancy title for the headpiece. That headpiece has airbags that massage the neck and compress on top of the shoulders.
9. The rollers of the MA73 actually reach up and over the top of the trapezia muscles at the top of the shoulders. The DreamWave uses airbags from the headpiece to massage the traps.
10. Both chairs have 3D roller massage technology (in other words, you can adjust the depth of the rollers for a more or less vigorous massage).
11. Customer support and warranty support for both chairs is now being handled by Furniture For Life, which is the distributor for both Inada and Panasonic in the USA. They actually send out a technician to repair your chair should anything go wrong with it.
12. Both chairs have 3 years parts and labor warranties and a less than 1% failure rate. Both chairs should also last you 15+ years. Great quality!!

I hope this helps. Let me know if these points bring up any other questions. I am always here at your disposal. One last thing…the DreamWave is a little better for taller bodies (can handle up to 6’5″ tall), whereas the MA73 is ideal for folks up to 6’3″.

Customer Question #2

Hi, I was wondering which massage chairs would you recommend for someone 5’10” to 6’4″, weighing 164 lbs to 200 lbs. Also for someone who works out at the gym so my shoulder and leg muscles can change. Has a deep tissue massage and for someone who has lumbar strain and neck and shoulder pain. These are the chairs I like: the Osaki JP Premium 4.0, Apex Ultra, uKnead Lavita, and the Infinity IT-8500.

My Response #2

uKnead Lavita massage chair
uKnead Lavita

Thanks for your email. All the chairs you mention are great chairs. They will all provide a good neck and shoulder massage. If you want a chair with the L-track, though, plus a good neck and shoulder massage, go with the uKnead Lavita. That is one of our top selling models right now and does a good all around job on the whole body.

The IT-8500 is an awesome chair, especially for the neck and shoulder area. The foot rollers are great and the stretch program is fantastic for anyone.

The Ultra will be too small for someone who is over 6’2″ tall, although it has a great neck and shoulder massage and a strong overall massage.

The Osaki JP Premium 4.0 is a good quality chair. Made in Japan, it is a better quality chair than all the other options you’re looking at. It is not ideal for someone over 6′ tall, so you might need to try it out before buying it to make sure it fits. It is manufactured by Fujiiryoki, the oldest massage chair company in the world.

I hope this helps. If you have any other questions, feel free to email or call me at 801-651-2026. I am always at your disposal.

Mail Bag: Some Questions & Answers Involving the Panasonic MA73

Panasonic MA73

Customer Question #1:

Hi, incredible website with so much great information! I am thinking of ordering either the new Osaki Summit or the Panasonic EP-MA73. I was leaning towards the Osaki Summit because of the L-track but am wondering which one offers a stronger massage as I like a really deep massage, and which one offers a better neck/shoulder massage?

My Response #1:

Hi, Jeff
Thanks for your email. Great questions. Tough to answer actually. The Summit is awesome because of the L-track, which the MA73 can’t even touch. Even though the Summit has a good neck massage, I’d have to give the nod to the MA73 for the neck massage. The MA73 definitely gives a better shoulder massage (top of the shoulder – traps). Both give a great massage between the shoulder blades.

I really love the extended roller track (L-track) so I might be a little partial to the Summit.

Customer Question #2:

hi alan
need to get new chair soon
the panasonic MA-73 looks interesting to us (dad and i) – mostly because how you describe it as being used for a regular chair also (to sit and watch TV – etc)
this is why we LOVED the sanyo 8700  — as it is a nice chair to simply sit in by itself off — or when using its super smooth slow massage (with no big intruding shoulder bags or arm bags – etc,)
and this is why I kind of hate the pro-dreamer I use  – as the shoulder bags interfere – and the arm bags are too big to allow normal arm placement on top when just sitting
few concerns I have about MA-73 —
1 – its not zero gravity – right?  I realize you can get that effect somewhat – but never its quite the same? having the seat incline as it should is a big deal to me – as my lower back is bad
2 – I like arm bags – but when not using them can one place arms “comfortably” on top without feeling they’re being forced up too highly (for simply sitting and watching TV)
3 – would you say this has one of the best neck massages ? and for somebody 6’2” ?
4 – are the calf/ottoman bag area big enough to truly do a good wrap-around massage on calf area. I find that many of the folding type ottomans lack the bigness or surface area to do calfs well
conclusion — the chair really does seem to be an ideal chair for us – except the zero gravity which I’ll never understand panasonic decision there

My Response #2:

Hi, Kim

Thanks for your emails. Great to hear from you again! Here are my answers to your queries:
1. The MA73 does not have the zero gravity feature. It stays static throughout the recline and during each program.
2. Yes, the arm rests are optimal for use without the airbags. You will sit quite comfortably, including your arms, when using the chair as a recliner.
3. Yes, it has a great neck massage…especially on the top of the shoulders. Plus you can adjust the 3D rollers to make the massage even deeper.
4. The calf airbags do not wrap around the calves as you are hoping. They are pretty shallow.

Customer Question #3:

Hello Dr. Alan!

I loved the free report. Found it very informative and helpful. My husband and I are looking to purchase a massage chair. Ever since my first pregnancy I have had sciatica, and we just happened to have the occasion to sit in a Panasonic EP-MA10 and a Human Touch 5.0 this weekend while shopping for furniture for our new home.
So that’s what got me scouring the internet trying to figure out what chair we should invest in, since I am now expecting our 3rd, and the sciatica and pelvic pain are 3 times as bad, 3 times earlier along in my pregnancy than before.
I’m not sure I know yet what chair is the right one for us yet. I lean toward Panasonic at the moment. My husband is 6 ft 2, and I’m 5 ft 3. It is quite the investment, and I want to make sure we can both benefit fully. I have been watching your videos on Youtube and reading as much as I can to make the best possible investment decision.
Thanks for reaching out.
Kind regards,

My Response #3:

Hi, Juli-Anne
Thanks so much for downloading my report and emailing me. Congratulations on your pregnancy! I’ve got 6 and it never got old!! I love just being a dad and a grandpa.
I might suggest taking a look at the chairs with the extended roller tracks (also called L-Tracks). They extend down the back and under the seat to give a roller massage to the gluts, piriformis muscles, and the top of the hamstrings. For someone who suffers from sciatica, I think this technology is an absolute revelation. You will be a butt massage like no other and it just may help your sciatica symptoms more than you’d expect.

Take a look at the Human Touch Novo XT, which is currently our best selling chair. It has the extended roller track, foot rollers, great neck and upper back massage, along with tons of other airbags and programs.

The uKnead Lavita is another L-Track chair that does a fantastic lower back and butt massage, as well as having a strong neck massage. Great foot rollers and arm airbags, as well as calf rollers!

Panasonics are fabulous chairs, but they don’t have the extended roller track. Take a look at the MA73, which has a roller track that goes down to the tailbone area and gives a fantastic roller massage. Great neck and shoulder massage (its roller actually massage the top of the shoulders, too. That is unique to the Panasonic MA73).

Check these models out and let me know what you think. When you are ready to buy, I’ll tell you what sales we have going on for each model.

Ask any other questions. I am always at your disposal.

uKnead Lohas Massage Chair

Massage Chair Relief logo
Massage Chair Relief logo
uKnead Lohas

We started carrying the uKnead line of chairs last year and began with the Lavita, which has been a pretty popular selling model for us. A few months ago they introduced the Lohas massage chair and we got a model for our Utah showroom. Here are my early impressions of the chair, without going into full “Review mode” and considering that the model we got for our showroom was an earlier Beta test chair and the current publicly released version is a bit different:

  1. Ergonomic Body Design – The body design is pretty sleek and is reminiscent of the Human Touch Novo XT. With this chair, the Novo XT and the new Infinity Altera, maybe this unibody design is the new standard of chair designs. I remember when the DreamWave came out in 2009 that many of the Chinese chairs released subsequent to it mimicked it’s design. Maybe this is the new trend.
  2. 50″ L-track – Just like the uKnead Lavita, the roller track is 50″ long. However, it feels different on the spine than does the Lavita. Of course each different model has it’s own feel, but I was kind of expecting the rollers to feel the same as the Lavita. It is definitely a different feel. And, although it is the same length as the Lavita, I didn’t feel like it hit as far down the hamstrings as does the Lavita.
  3. Foot & Calf Rollers – Most chairs nowadays have foot rollers, but still very few have any form of
    uKnead Lavita
    uKnead Lavita massage chair

    calf rollers. The Lohas (and Lavita) has a disk behind the calf muscles that rotate and stroke the gastrocnemius in the process.

  4. 3-Stage Zero Gravity – You have 3 options for zero gravity (although, honestly, there is only 1 true zero gravity position) so you can recline the whole chair while simultaneously raising the ottoman down to 3 different positions.
  5. Space Saver – You can place this chair close to the wall, if you’re tight for room space, because of the way the chair reclines. It rotates down and away from the wall when reclined, allowing you to place the chair only a couple of inches from the wall.
  6. BlueTooth Connectivity and Speakers – Pair up your device with the chair and listen to your device’s playlist over the stereo speaker set up.
  7. Other features include 48 airbags, 8 auto programs, heat, 1 year parts & labor in-home warranty (with a 2nd year of parts coverage), quad rollers, user weight recommendation of 285 lbs, user height recommendations of 5′ – 6’3″, and quick keys on the right arm rest for rapid deployment of the massage.

The Lohas is a nice, compact massage chair that gives you a vigorous massage while also looking pretty dang good at the same time. It comes in mocha or black interior with a cream outer shell. Priced at $3895 at the time of this writing.

New Massage Chair Models at CES!


I visited Las Vegas from January 5-7 this month to meet with a bunch of the companies who supply the massage chairs we sell. I had the chance to meet with Inada, Infinity, Luraco, Human Touch, and uKnead. It was a great visit and I got some good video footage of some new models. The video is below, but here are the highlights for your perusal:

  1. Inada has a new model coming out in April called the Inada Nest. It will be priced at $5999 and has some pretty cool features that we’ve not seen before in a massage chair. First of all, the rollers are “pumpkin” shaped in that there are ridges on the massage rollers. It makes for a somewhat different massage experience, particularly in the top of the shoulders area. I really felt those rollers hit my levator scapulae muscles (tight muscles at the top of your shoulder blades).Secondly, the Inada Nest has quad rollers, each side of which are independent of each other. In other words, the left and right rollers work independently of each other as the rollers go up and down the spine. In my mind’s eye, the practical application of this would be for spines that have muscles imbalances from right to left, i.e. scoliosis perhaps. The rollers would address the hypertonicity of each side as differently as the muscle tightness might be from side to side. Pretty cool, actually.
  2. Luraco introduced it’s new 3D L-track chair, the Luraco Legend. This chair won’t be available until the 3rd or 4th quarter of this year, but it will be the first non-Chinese made L-track chair, which is interesting. It will be priced at $6499. Some of it’s features include a 58″ roller track, which actually massaged the belly of my hamstrings (I’ve never had an L-track reach that low down my thigh), 3D rollers that have separate intensity adjustments for different areas of your spine (in other words, you can make the neck massage stronger than that of the low back and/or buttock area), foot rollers, and can handle taller bodies as well as shorter bodies just like the iRobotics 7 does.
  3. Human Touch introduced their Novo XT around the beginning of the holiday season in 2016, but they never had inventory until the end of December. Now, they are out and about and there were some on display at CES. We actually have a floor model in each of our showrooms. Great chair. It is a 3D L-track chair that can handle taller bodies and has a very easy remote control to use, plus a lot of automatic programs to play with. It has foot rollers and Bluetooth, as well as a space saving feature. You can check out the chair already on our website.
  4. uKnead is introducing a new model, called the Lohas, to their line up. At this point, we only carry their L-track Lavita, which has been a pretty steady seller. The Lohas will also be an L-track, but has a sleeker body design. It also includes calf rollers, foot rollers, calf airbags that can flip up and massage the knees, quick access keys on the right armrest to control the positioning of the chair without having to fiddle with the remote control, Bluetooth connectivity, and a space saving feature. It will be priced at approximately $3895 and it will not be available until April.

Here is the video of my visit to CES with some conversations with the company folks talking about their new chairs…

I hope you found this interesting and helpful!

Customer Question #1

This site is amazing. I just can’t decide which chair to buy. I have been looking most closely at the Inada Dreamwave, Panasonic MA73, and Osaki 3D Pro Dreamer. I sit at the computer most of the day and get back pain (upper and lower) and lots of tightness around the shoulders, I also get very tight in the illiotibial area. I like tons of pressure when I get massages. Any recommendations on the chairs I am looking at or suggestions as to others to look at? Thank you so much.

My Response #1

The chairs that have the best IlioTibial band airbag massage are the Inada DreamWave and the

Inada DreamWave
Inada DreamWave

Panasonic MA73. Although the Osaki Dreamer has hip airbags they are designed to hold the hips in place to accentuate the low back roller massage. Those airbags don’t really do much to the IT Bands. All of those chairs, however, will give you a great shoulder/upper back massage along with a good lumbar massage.


Two other chairs you might consider would be the Infinity IT-8500, which is our most popular chinese-made chair. This model has a great neck and shoulder massage and is among our most intense and vigorous massage chairs. We also now have this new Titan Alpine chair that has the extended roller that goes down into the butt and top of the hamstrings. It offers an awesome lower back/hip/buttock massage. This extended L-Track has become the next big thing in massage chairs because finally massage chairs can offer roller massage to the buttock area, which has heretofore only been addressed by airbags in the seat. By the way, although both of these chairs have great massages, neither really does much for the IT Bands.


Customer Question #2

Hi Dr. Alan,
I liked your report, there are so many options and features in the chairs out there, it is good to get some condensed information as is in your report.

I recently started looking for a chair and one very important feature, probably number one in my book would be to have the chair work as much of my thigh area (from glutes to behind the knee) as possible. As such, it seems like the L track models would be the best, from what I’ve seen the Titan 8400 seems to have one of the longest travel lengths.

With that said, how would you describe how far below the glutes it would travel?
Any other thoughts in this area?
I know the Titan is a newer brand name for you to carry, what has your experience been with them?
Are there any new features in the thigh area coming out soon from other models/chair manufacturers?

Thanks very much, I appreciate your input.

My Response #2

Hi, Gary
Thanks for your email. The L-Track of the 8400 extends to the top of the hamstrings on me, and I am about 5’9″ tall. For a shorter-legged person, it may extend even further down. The new Titan TP-Pro Alpine has a similar roller track and hits about the same area. These new Titans along with the Infinity Iyashi (the original extended roller track massage chair) have become quite popular because of the L-track. It is a great feature for folks with low back, pelvic,and or gluteal issues.


Although Titan is a new category for us, they have been around for quite some time. These new models

are an upgrade over previous, cheaper models and that is why we have begun carrying them. They are owned and imported by the same company that produces the Osaki chairs. I have had plenty of dealings with them.


You might also take a look at the uKnead Lavita massage chair, which has a longer L-track than most and seems to reach down to the belly of my hamstrings. It isn’t much more money than the 8400 but seems to do quite a bit more and reach a little further.


Customer Question #3


Dear Dr. Weidner,

First of all, I cannot thank you enough for using your contacts to try and negotiate the situation with Panasonic.  I must admit I am finding this imbroglio quite instructive.

So school is about to start again—I’m pursuing post-baccalaureate studies to earn credit toward a Master’s program I’m applying for–and I need a working chair in order to treat rather severe back spasms (and thus spare opioid analgesics).

Now, I am considering the Inada Dreamwave versus the Inada Flex.  I know that the Flex does not have the function that mobilises the lumbar vertebrae: but might you be able to explain to me the advantages of the “Dreamwave Technology”; and, what is your opinion as to the clinical mechanism by which it exerts the analgesic effect?

And might you be able to help me think about how the Dreamwave and the Flex compare in other respects?

As always, I am grateful for your assistance. Your help has been invaluable. Please let me know how I can implement my testimonial to your greatest advantage (facebook?).



My Response #3


Hi, James

Thanks for your email. Before I answer your questions, I will just let you know that Panasonic requested

Inada Flex 3s
Inada Flex 3S

your address and phone number yesterday because they will have someone calling you (this week, I suspect) to arrange pick up of your chair to repair it. I have been rather impressed with Ellison’s response to your issues. I hope you feel the same.


Now, regarding the DreamWave and Flex, I actually wrote a 2-part comparative review of these chairs. You can check out both parts here:


The DreamWave program of the chair actually involves a number of different components:


  1. The DreamWave feature itself, which is the seat moving up and down and side to side, through a sophisticated deployment of airbags, to mobilize the pelvis and lumbar spine. This is very soothing, particularly for someone in acute low back pain,


  1. The thigh airbags inflate to massage the IlioTibial Bands, which are invariably tight in folks with low back, hip, or knee pain. Not many chairs actually dig into the IT Bands, the DreamWave being one of them,


  1. Waist airbags inflate to rotate the lumbar spine, and


  1. The rollers work over the lumbar spine. One of the great features of the DreamWave is how low the rollers go. Not including the new extended L-Track chairs, the DreamWave goes lower into the sacral area than any other chair I know. You will love that about the chair.

L-Track: What’s the Big Deal?


L-track is a relatively new phenomenon, first introduced in a brand name chair with the Infinity Iyashi about 3 years ago. It has become, in my opinion, one of the best feature additions to the massage chair industry in years. The L-track is a name given to a the feature otherwise known as the extended roller track.



All chairs prior to the introduction of the L-track, had a roller track that began at the neck and then went down to the lower back and, in many instances, the top of the gluteal muscles (butt muscles!). The longest track I’d seen in the traditional roller track configuration was 32″…still is. That seemed to be the longest track that could be created to hit the entire back from neck to the top of the pelvis.

I might also add that the roller tracks of which I am speaking were designed in a sinusoidal shape, in other words, an S-shape. Thus the term “S-track” had become quite popular when describing this roller track. This design was for matching the shape of the spine, which has forward curvatures in the neck and low back, and reverse curvatures in the mid back and pelvis. Without the S-track development, the user would not get a full, optimal massage of the two forward curves, i.e. the neck and low back, which, incidentally, just happen to be the two areas for which most folks are looking for help and pain relief.

The S-track was great for offering roller massage therapy along the curvatures of the spine DOWN TO the low back. But, what was available for the region below the low back, i.e. the butt and hamstrings? All that was available was the same technology that was used on the legs, feet, arms and hands…airbags to compress and passively move the pelvis. Now, I will admit the airbags passive motion and compression is better than nothing for the pelvic region, but those airbags really did very little in the way of significant therapeutic massage for those muscles.

Inada introduced it’s “DreamWave” technology in 2009, with the Inada Sogno DreamWave massage chair, which was a fascinating innovation at that time. In a nutshell, the DreamWave technology was passive motion of the seat from side to side, in conjunction with waist and IlioTibial Band airbags working in concert to passively move the hips from side to side and up and down. Brilliant! As a chiropractor who had dealt with countless severe low back pain patients, this innovative design was a phenomenal idea for passive motion to an area that no therapist could directly manipulate because of the intense pain of the patient.

Many chairs have imitated and copied the DreamWave technology. You may see it named differently by different massage chair companies, i.e. “swing”, “slide”, or just plain old “seat massage”.

Although this DreamWave technology was and is fantastic, it did not directly massage any of the muscles in the gluteal area. Now, what is it important to try to massage those muscles you ask? What’s the big deal?

Well, I would propose three reasons:

  1. Gluteal muscles – these are the some of the largest muscles of the body and get used every time you stand, sit, walk, run, or shift the position of your body. They are typically weak in most postural problems, but they also tend to have trigger points in them, which are localized muscles spasms that can cause significant pain and discomfort when manipulated and, in some cases, refer pain distant to the area of spasm.
  2. Piriformis muscles – These are often the little known culprits of sciatica pain, which is a very common malady seen in a chiropractic, massage therapy, and physical therapist offices. WebMD defines sciatica as “anything that puts pressure on or irritates this nerve (sciatic nerve) can cause pain that shoots down the back of one buttock or thigh. The sensation of pain can vary widely. Sciatica may feel like a mild ache; a sharp, burning sensation; or extreme discomfort. Sciatica can also cause feelings of numbness, weakness, and tingling.” That “anything” that can put pressure on the sciatic nerve can be a herniated disk, degenerative/arthritic bone spurs, or entrapment/impingement by the piriformis muscles (one on each side of your body). In my clinical experience, it is not uncommon to see this type of sciatica in women who have gone through the pregnancy experience. The pelvis actually changes configuration with the growth of the fetus, as the hip bones tend to flair out. That change in configuration lends itself to biomechanical changes to the body and, thus, trigger points to the piriformis muscles and entrapment or impingement of the sciatic nerve. Of course, I saw piriformis muscles problems in men, too, as a result of other onsets of biomechanical strain. The bottom line is that it can be very painful!
  3. Hamstring muscles – these muscles run from the pelvic area down the back of the leg to the knee area. Most, if not all, of you have heard of a hamstring injury. Well, the hamstring is typically a very tight muscle in most folks. It can restrict the motion of your lower body quadrant when ambulating (walking or running), which can lead to other issues like low back pain.

Massage chairs have not addressed these muscles very well in years gone by. Airbags are great, but they will not effectively offer therapeutic massage to these muscles groups that rollers will. Until now…

This is where the L-track roller massage really helps.



I mentioned at the beginning of this article that the traditional S-track roller track configuration went from the top of the spine to the bottom of the spine. The L-track was designed to go beyond that low back area and hit the very muscles I just described. The L-track continues on down the body beyond the low back to hit these butt muscles and offer therapeutic roller massage to those oft-neglected muscles. That is why it is called an L-track…because it goes beyond the back and runs under the seat, in an L shape.

These new models with the L-track rollers will, at the very least, massage the gluteal muscles, the piriformis muscles, and the head of the hamstring muscles. We are now beginning to see chairs with even longer roller tracks, like the new uKnead Lavita massage chair, that are actually hitting/massaging the belly of the hamstrings. Instead of roller track lengths of only 30-32″, we are seeing in these L-track chairs roller track lengths of up to 51-53″ long.

I mentioned at the very beginning of this article that I thought the L-track was the greatest innovation in the massage chair industry in years. The reason I feel that is because of the therapeutic effect this feature has on the three groups of muscles, heretofore mentioned. If you have low back/buttock/sciatica pain, the L-track feature will have a far greater chance of helping you out than the traditional S-track chair. Those rollers will hit muscles you didn’t even know you had! Once you sit on an L-track chair you will know exactly what I mean.

I will just mention that today’s L-track chairs ALSO still have the S-track configuration from the neck to the low back. The roller track just goes beyond the traditional S-track configuration to the under the seat. So, you may hear folks say that a chair is either an S-track or an L-track chair. That is an easy way to differentiate the two, but REMEMBER that an L-track chair always has the S-track configuration, as well.

I hope this was beneficial!
