Mail Bag – Iyashi Concerns; Customer with Cancer; Zero-gravity vs. Zero Embrace

CUSTOMER EMAIL #1 (Infinity Iyashi concerns)

emailThanks for the follow-up Alan. There are certain things we really enjoy about the Iyashi but others that have us puzzled and unsure of our decision.

1. love the ‘wall-away’ feature
2. the bluetooth is nice cause it indicates to me that there may be future customization capabilities with programming
the routines of the chair (possibly just wishful thinking on my part?)
3. the very long track on the back rollers that takes it past the glutes to the upper thighs – very nice!
4. the heat and zero gravity features

1. the controller doesn’t seem very intuitive to us – it appears straight forward until you begin using it and then it leaves us a bit baffled because when you go to certain functions you can see and even highlight them at times but when you do there is no apparent change to the performance of the function?
2. the foot roller air bags in ALL routines that we’ve tried are painfully over aggressive and try as we might we can’t figure out how to mellow them out and it really diminishes the enjoyment from the overall experience
3. the neck/top of shoulder routines on the other hand seem to come up a bit weak
4. the air bag treatment of the IT bands along the outside of the legs also seem a tad whimpy

So, long story short, we’re probably at around a ‘3-star’ rating at the moment for the Iyashi. We’re considering checking out the Inada a bit further to see if maybe that will fit our needs better. The distribution center is only 15 miles from us so it will be easy for us to compare the two in a few weeks once we’ve thoroughly explored all that the Iyashi can do. Thanks again for all your great help. Our experience with your company is a definite ‘5-star’! Jeff


Iyashi - side view reclinedHi, Jeff
Thanks for your email and the update. Here are a few comments regarding the cons in your email…

1. Many of the things that you try to change on the remote during automated programs do not work. Some of them, i.e. speed and region (or “part”) cannot be altered because they are all preset during the automated programs. This is true of pretty much all massage chairs. There are certain functions that can only be changed during the manual settings.

2. Regarding the airbags, did you go into the remote and select the “Airbags” function? This is one of the functions you CAN change in auto or manual settings. I believe there is a ranking of 1-5 or something like that which represents the intensity of the airbag inflation. Give that a try.

3. When you first begin an auto massage, watch the remote control for an indicator called “shoulder adjust” or something like that. Then push the up arrow to move the rollers up the neck. This will override the body scan in the area and work on your neck a little better. Some programs, like “Refresh” have a more aggressive neck massage than programs like “Recovery”. Also, when you set up the rollers in the neck manually you will find that the massage is more aggressive in that area. I would also say that, compared to the phenomenal low back roller massage, the neck is definitely weaker comparatively speaking.

4. The airbags on the sides of the thighs are not designed to massage the IT Bands, as they are in the Sogno or Panasonic MA70. They are there to do one thing and that is to move your hips and pelvis over the butt rollers to increase the intensity of the buttock massage. It is a very unique feature to this chair only. So, I think you are comparing those airbags to those of the Sogno, which are intended for a completely different purpose.

I hope this helps. Stay with it and keep becoming familiar with your chair. Let me know if you have any other questions. I am always here at your disposal.


CUSTOMER EMAIL #2 (Customer with bone cancer)

Dr. Weidner, I’m seeking relief from chronic back pain and am considering the Osaki OS 4000. I’ve had sciatic pain in my right hip for several years which mostly manifested at night after 3-4 hours sleep. I am now suffering from cancer that has invaded my bones and may be contributing to my back pain. Do you think this chair will provide me any relief? Thank you.


medical-doctorHi, Brian
Thanks for your email. I think that if your pain comes from musculo-skeletal issues, a chair can really help out. My concern would be with your cancer. I don’t know the details of your situation, but massage may be contraindicated. You will need to confirm with your oncologist about using massage to treat your musculo-skeletal complaints. If you are good to go, then a massage chair might just be fabulous for a reprieve from some pain. The OS-4000 is a good, decently-priced chair. You might also check out the OS-3000 Chiro which has a longer roller track and may do more to help your sciatica issues. You could also look at the Infinity Iyashi, which also has a super long roller track that could work your buttock muscles (i.e. piriformis muscles), which may be contributing to your sciatica.

I hope this helps. But, please consult with your doctor first before making any financial commitment to massage therapy of any kind.

CUSTOMER EMAIL #3 (Zero Gravity vs. Zero Embrace)

hi doc.
i had a question about the pro-marquis. what is the difference between zero-gravity and “zero embrace”. they dont advertise it as a true zero gravity chair. i was wondering if this is a significant difference. thanks.

Thanks so much for your inquiry. Yes, the “Zero Embrace” is confusing and a vernacular that Osaki probably shouldn’t be using as it creates a confusion in the mind of the shopper. According to Osaki, Zero Embrace is different from Zero Gravity.

Zero Gravity alludes to the tilting of the seat to 30 degrees and an articulation between the seat and the reclined chair back of 120 degrees. Often associated with zero gravity is the raising of the ottoman to a point that puts the lower extremities (legs and feet) above the horizontal level of the heart. That is not necessary, however, for a true zero gravity position. In a true zero gravity position, the knees are bent somewhat, creating a break in the line between the thigh and the lower legs.

Zero Embrace, on the other hand and according to Osaki, alludes to a reclined position where the lower body is higher than the upper body. The seat does not tilt up at all, as in a zero gravity position, but the chair back reclines to a point where the upper body is positioned lower horizontally than the lower body and seat. I don’t know what the therapeutic value is of this feature, but I’m sure it is meant to sound like zero gravity though it is not that at all.

I hope this helps in some way. Feel free to email me or call me at 801-651-2026 if you have any other questions or need assistance with your order. I am always at your disposal.
