Do I need Indoor Setup (also known as white glove service) or can I do it myself?

- The chairs are easy to assemble.  It only takes about 20 minutes.  The only reason assembly is required is because most chairs ship with the arms detached to make it narrower, lighter and easier to move into your home.

- The assembly is basically just screwing the arms to the chair.  It includes easy to follow instructions and does not require special tools or skills.

- If you want them to setup the chair inside your home, you can select the option for “Indoor Setup & Assembly”.  We don't recommend it for most people it because it's an easy way to save yourself the money.  But we're happy to add it to your order if you'd like.



Canadian customers

- Yes, we ship many massage chairs to Canada.  Total turnaround time is typically about 2 and a half weeks.  We make it easy by handling all of the importing paperwork.  We also pay for the customs brokerage and filing fees. 

- GST (usually 4.9%) and duties if levied, would be billed to the customer.  Duties have never been levied on massage chairs we’ve shipped to Canada.

Wife love the chairReview by Tarek Mekhail
Gave it to her for Christmas and she loves the chair. Instructions are not very good but not hard to put together. (Posted on 3/7/2018)

Osaki Zero Gravity Massage ChairReview by sky111
I rated it! I have spent thousands on co pays for physical therapy and 60 bucks a pop on massages due to degenerative disc disease. I am a hairdresser of 35 years and Have had difficulty with my spine situation; But I HIGHLY recommend everyone have one! This has definitely been the best investment I ever made! Thanks to Amazon, I saved $1000 by them comparing the one I was going to buy to this one for me. It is totally awesome!!! (Posted on 2/14/2018)
Can't beat the features for the priceReview by TonyP
We got this over a year ago. For the price, it's unbeatable. I see people complaining of assembly. Except for the size of the components, the assembly is not that difficult. Easy to assemble if you've two people. Sometimes some tools fitting to some screws could be a bit difficult. Overall they've done a great job. Manual is pretty useless. For the amount of features on the remote, you'd expect everything to be detailed. But you don't really need a manual for this except for the assembly. You can figure it out all by yourself. It's got extensive custom controls and trust me except me and the dog ;-) , no one can figure out to use some of the controls. The programmed massages are good. I like one of two of them mostly and repeat the same. But the spot massages are great. The zero gravity is fantastic. There's also a custom adjustment after setting to zero gravity you can lean the chair further back all the way to a steep angle and it's very good for blood flow to your head. The chair is perfectly balanced although you would think at that you'd fall back, but you won't. I love this aspect. Also love the heat for the back. Esp. if the back muscles are sore, the heat is really great.
If you try other brands for these features it may cost well over 5K. So for less than 3K, you can't beat it. We didn't see any problems with the mounted remote. The mini remote is a IR remote so you've to point it to the main remote. They could have made it RF remote and it would have been fantastic, so you don't have to take your hand out of the chair everytime to adjust during massage.
The chair is heavy and mind you, make sure you put a padding or something under the 4 corners of the chair , otherwise the material leaves a stain on the carpet, which is hard to remove.

ONLY WARNING: When you're planning on moving , make sure if you can you move the whole chair as is. Otherwise if you disassemble it by disconnecting the air pump pipes, it would be a bit difficult to hook them back. Because they run a metal spring inside each of these rubber pipes, they tend to stick out, which makes it extremely difficult to plug them back. Also the air pipes are snug and doesn't have too much length in some areas and it would take great effort to plug them right. (Posted on 2/14/2018)
Wow!Review by SuzieQ
I bought this for my brother for his 70th birthday. He loves it! So does his wife. We put it together ourselves and I tried out the demo mode. OMG, amazing! The only thing to note is that it is quite heavy so don't plan on moving it around much. (Posted on 10/26/2017)
My hubby's favorite chairReview by Jade z 01/21/17
It has been 6months since we own this chair. My hubby and I use everyday we love it. Also very good looking massage chair. It scans your back before starts so different heights of people can use. Heat feature is very nice. You can program a part of your body massage like only feet, only back... only concern is I hope the neck massage is more strong than now. Otherwise it is really good massage chair for the price.I highly recommend!! (Posted on 2/1/2017)
Fantastic Massage Chair!!Review by glorysong95 07/16
My uncle was here visiting from Atlanta and he has been having severe back pains and muscle cramps. So we went to tryout some massage chairs and this massage chair met his every need. I too tried this massage chair and it felt like an out of body experience.

The OS-4000CS is truly a full body massage chair and it adjusted to fit both me and my uncle to our size. The rollers were intense and covered the entire body from neck to bottom. We tried all 6 massage styles and each felt unique. The two stage zero gravity positioning made it feel even more comfortable and relaxing. The lumbar heating pad was a nice feature as well. The features for shoulders, arms, hips, thighs, and feet were also extremely therapeutic as well.

Overall, comparing the prices and functions of different massage chairs, this chair was the best value. Even the size of the chair seemed manageable and space efficient. I would highly encourage the OS-4000CS to anyone on the market for a professional full body massage chair. (Posted on 2/1/2017)
Everyone loves it , even the cat!!Review by Alexander Don-Doncow
Very nice, sophisticated and seemingly decently made massage unit. Perfect match for the much more expensive Inadas.
Lots of options, although not perfect. I could wish for a few programming capabilities but I am really nitpicking here.
All functions are adjustable within a fairly broad range, it should please almost everybody.
Incredible variety of different types of massage. Worth exploring because the manual, as most Chinese manuals, stinks.
The unit is heavy and difficult to assemble. It is not complicated, the components are just very heavy.

From my own experience I should warn prospective buyers that this IS NOT A THERAPEUTIC UNIT, it is a purely relaxation and pleasure machine.
Although I have no chronic deficiencies, I do sprain my back and other parts occasionally, this machine not only does not treat
such injuries but it actually may seriously aggravate them. If you have any health issues especially physical issues most definitely consult with your physician before buying and/or using this unit. (Posted on 8/4/2016)
Good deviceReview by Igor V. Zavoychinskiy
I use it for just several day so far so, it's just first impression for now. The chair is of very good quality: solid design, components fit well (it comes disassembled), leather (or whatever it is) is of good quality. Chair has a lot of settings which I didn't yet investigate. Though, there are four presets you can use right away. I liked "Circulation" and "Relax". Tried "Smart" but found it too aggressive - feels like you're being tortured thru crushing. There are also "subsets" you may choose with just one click of a button - "Back & Lumbar" is my favorite.

I'd also note "Zero-G" mode. It's advertised as a key feature of the product and it's really cool. You may enable this mode for some massage types but not for all. In this mode chiar puts you in kind of horizontal position. It's comfortable and massage feels much better. If you gonna use this mode you must ensure there are at least 23" of free space behind the chair. So, you cannot put it close to a wall.

Some cons noticed so far:
1. Remote control has very limited sensitivity - you need to target very precisely if you want it working. Btw, remote control is not advertised. It has only basic features like "power", "zero-g" and some strength adjustments.
2. Main control board is mounted on a metal stick which is very unstable. It's hard to operate using just one hand and if you're using Zero-G or any other horizontal mode one hand is all you have.
3. Assembling manual is a bit outdated. Though, I figured out what to do without any problems.

When you request delivery be aware of three things:
1. It's really heavy! Total weight is about 200lb. Max weight of the biggest part I'd estimate to ~120-140lb.
2. Chair comes in two boxes and one of them has dimensions 50" x 30" x 38". In my house I have doorways of 31" width and due to layout it was impossible to move both boxes to the room so, delivery guys left the biggest one in the garage. I had to move all parts to the target room by my hands and it wasn't fun.
3. Even if you don't need to move parts throughout your home you still need assistance of another person to assemble the unit. You can do it yourself but trust me - it doesn't worth it. You buy this chair to *heal* your back, right? (Posted on 8/4/2016)
