Customer Reviews (57)

I love this chair...butReview by Emily
This is an excellent massage chair. It has options to massage your entire body and fits me perfectly. However, the beeping is terrible. There should be a mute option. Nothing ruins a relaxing more than the loud beeping. I would give this chair 5 stars but the beeping drops it down to 4 for me. (Posted on 12/22/2015)
overall the chair is "Great"Review by GP
1. On a scale of 1-5 how would you rate your chair? Why?
- Rating of 4 out of 5. I'm 5'7" and the chair fits me perfect, but my wife is only 5' so the foot rollers barely touch her feet and shoulder airbags are too high and cannot be adjusted. But overall the chair is "Great".

2. Was there a specific reason you bought a massage chair? (related to pain, injury, replace getting massages, wanted to start getting a massage, other)
We purchased the massage chair for working out sore muscles, stress relief and relaxation.

3. When do you usually use the chair?
We use it daily. Generally we use the chair in the evening after work to help relax after a long day and stressful commute.

4. What is your favorite feature, program, or function?
We love the "Muscle Relief" program the most along the flexibility to target specific areas.

5. Do you have any tips that may help future customers?
If possible, tryout different types of massage chairs to fit your budget & needs. We found the zero gravity massage chair was the most effective for us and fits our needs. staff was very helpful and service was outstanding.

6. How did you feel about our customer service? has a wonderful Customer Service department, they respond quickly and are always willing to help.

I cancelled 12 pre-paid massages with my massage lady after I received itReview by Cally
Thank you for asking for my input regarding my massage chair. The fact of the matter is I love it! I cancelled 12 pre-paid massages with my massage lady after I received it. I no longer feel a need to visit her office. The only thing the chair lacks that she provides is oil and soft music. Now, to answer your questions:

1. I would rate the unit a five out of five. It provides me with relief as promised.

2. The main reason I think I purchased the chair was to replace getting massages. Its so nice to have it at the ready whenever I am and not have to schedule appointments with someone then wait for them. Comfort is at the touch of a button.

3. I don't have any specific times that I use the chair, just whenever I feel like I would like to be pampered for a few minutes.

4. Actually, I don't have an actual favorite as I am still experimenting with all the functions. It would be most helpful though if you could include a more detailed manual describing when shipping the unit.

5. I placed the chair in an area that is not in the main flow of traffic or near a television. I have placed it in a quiet room that doesn't attract people who are seeking noise and/or company. I find that when it's quiet I can relax more and simply enjoy the chair. I have allowed some adults to try it and it isn't for everyone I find. I personally like the sensation of pressure it gives and then release. It's too intense for some who have tried it. (and that's fine with me, now they'll stay out of it)

The customer service I experienced was outstanding. Emery who I spoke with was very good. He needs an "atta boy"!

My husband and I each use the chair twice a day We have never felt better and more relaxed. Aches and pains melt away as we use the chair. One of the best investments we ever made. (Posted on 9/19/2015)
Tight in the shouldersReview by Tim B
Bought this chair for a friend and he ended up not wanting it. After a week of use we enjoyed the chair but found that it wasn’t very deep. I'm also 6 foot and the fit in the shoulder area was pretty tight and uncomfortable. I felt like I had to squeeze into it. We ending up decided to exchange it to the Osaki Pro Dreamer, because we felt we would regret it if we didn’t. The Dreamer chair is much deeper in the neck and shoulder area, and the fit is much nicer in the shoulders. I do recommend that if your over 6 feet or have broad shoulders to look at chairs with more shoulder room. is also everything that I read. Their staff is outstanding and they made the exchange process as easily as it could be. I would recommend calling them if you have any questions.

Great valueReview by Sammy P
We bought the Osaki 4000T in May and have been using it all the time. I originlly saw the chair at Costco but after talking to the Emassagechair staff they explained that the OS-4000T has foot roller and the OS-4000 does not. We liked the idea of the foot rollers, and they are awesome for tired feet. However, one thing we did notice after our friend used it was that if you are taller say 6' or higher you may find the chair a little tight. Other than that chair is great so far and it definitely helps with our aches and pains. (Posted on 8/9/2015)

Very nice chair. Review by Herb
Love this chair! So does the entire family! Installation a little tricky but we are glad we bought it! Zero gravity position puts me to sleep! (Posted on 10/3/2014)
Awesome chairReview by G.S.
This chair is heaven sent. It is even better than described online. Great deal and wonderful service from We couldn't be more satisfied or happy. (Posted on 8/13/2014)
Love this chairReview by Tired momma
I get have problems with my neck from standing in front of a computer all day at work. 20 minutes in the chair when I get home does wonders for me. Zero gravity, heated seat are terrific! Only disappointment is the head rest really doesn't do much except inflate. (Posted on 8/13/2014)
Oh how I love this chair. It is more than I was hoping for because there are so many different ways to use it! I have all my family rushing into the house to see who can use it first.

If I need deep muscle massage one day, I can get it. If I need just a soft air massage the next day, I can get that too.

I would recommend this to anyone who has a chronic pain disorder because it really helps the pain from my osteoarthritis and Fibromyalgia. It makes you forget the pain for a while, (Posted on 6/16/2014)

NoisyReview by Teaguer
The chair works well and provides a great massage. The zero-gravity feature is very relaxing. The issue I have with the chair is that it is becoming noisier all the time. The massage arms sound like they are grinding. I have contacted and they have helped me get in touch with Osaki to figure out what the issue is. (Posted on 4/17/2014)
greatReview by zeb
4 months use everyday love it (Posted on 4/16/2014)
YippeeReview by Deanna May
I feel like I got a steal of a deal on this chair---It does everything listed and more. I can't help but brag to all of my friends! They all want one now too. I got the new 4000T and my tootsies thank me every time I use my chair! I have the cream color and it looks stunning in my bedroom. My brother and my husband had it up and going in about 45 minutes (the manual is a little skimpy but it wasn't hard to figure out) and we've been relaxing to our hearts desire ever since. Thank you for making the purchase and delivery easy, easy, easy! (Posted on 4/14/2014)
