Computer Body Scan

Equipped with the latest technology, it allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage hitting all the key areas. Regardless of your body type, this highly advanced chair will self-adjust making each massage experience feel customized

Unique Foot Roller

Located on the bottom of the feet are 2 rows of spinning reflexology massagers which provide a soothing kneading style application. As the rollers spin it will stimulate acupuncture points and as the air bags inflate it will generate a much deeper massage along the bottoms of your feet.

Zero Gravity Massage

Inspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This feature improves spinal decompression and decreases muscle tension of the spine. There are 2 stages of zero gravity, the 2nd being more reclined. When reclined fully, to where your legs are higher than your heart level, the therapeutic effects are incredibly effective and may be felt immediately.

Next Generation Air Massage Technology

Osaki OS-4000T has re-engineered and has developed the next generation of air massage technology, streamlining the air massager to a lower count. Through innovative engineering, we have reduced the total number of air bags but have increased the volume and surface area of massage. By doing so the total number of working valves has drastically reduced from prior model. Which ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs in the market.

Arm Air Massagers

Along with mechanical advancement, the material has also incorporated some upgrades, such as the arm massaging area. Using a durable spandex , the bottom portion of the arm massager has been lined with small rubber bumps to invigorate the senses as the air bags compress the tops and bottom of the forearm and hands.

Auto Recline and Leg Extension

This chair defines luxury. Fully automatic to make every movement effortless. The simple to use remote control allows you to operate the foot extension, leg rest, recline of backrest, and the zero gravity position.

Wireless Controller

Located on the top right of the main remote you will find a compact wireless remote allowing you to control the main features of the chair without having to struggle to reach the main remote in the reclined position.

Calf & Foot Massage

There are multiple air bags along the sides and back of the legs and feet which inflate to apply a compression massage. Located along the bottom foot massager are spinning rollers that apply a concentrated pin-point kneading massage.

Lower Back Heat Therapy

Placed in the lower back region of the chair are 2 heating pads that enhance the massage experience.

Shoulder, Lumbar & Hip Squeeze

In the upper to mid portion of the chair, the air bags are programed to inflate at independent times, which causes the body to twist, creating an enjoyable deep stretch. Stretching is applied to the shoulders, lower back, hips, and thighs.

Full Size Easy-to-Use Remote

The OS-4000T remote presents one of the largest viewing screens to easily visualize what functions the chair has activated. There is also a flip down cover to access the manual functions of the chair. The remote allows you to select the massage type, intensity, speed and location. You can also independently  select   the area of airbag massage . The manual mode massage includes kneading , tapping , shiatsu , rolling , combination and Swedish.

Osaki 4000T Massage Chair Remote

  • Air Intensity Adjustment - The air intensity of the air bags can be controlled up to 5 levels, from mild to strong.
  • 3 Levels of Intensity for the massage - The roller heads that apply the massage to the back, can be extended outwards causing the rollers to press more firmly along the back. This will result in a more vigorous massage.
  • Massage Speed Control - The speed in which the massage heads move can be controlled up to 3 different speeds , ranging from slow to fast.

Auto Leg Scan

The calf and foot massager is capable of making adjustments according to each individual's leg length ensuring that the massage air bags are concentrating on the correct areas. At the start of the massage, the chair will fully extend out and then retract. Once the foot massager has reached the desired length, firmly press your totes down to indicate the chair to stop.

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.

Massage Chair 3years Warranty - Titanchair.com

Since youll be receiving the Free Extended Warranty for the holidays, you will be covered for a 4 year manufacturer warranty on the parts. And for the first 2 years, in home labor service is also included.

A qualified technician would be sent to your home to provide service if you ever need it. You never have to ship the chair for service.

Love the chairReview by Tim C.
Love the chair (Posted on 8/11/2019)
This is a great chair!Review by Stephanie C. on 1/9/2014
I bought this massage chair a few of weeks ago for my boyfriend for his birthday. He's had back problems from a car accident a while back and I was hoping it would help. I got the white glove delivery because I had issues putting my coffee table together, I wasn't even about to attempt a sophisticated piece of electronics.

I knew the chair would be heavy.. but DANG! Two delivery men showed up (on time) and carted two GIANT boxes into my home. They had me try it out to make sure it worked before they left, I was impressed, and I was excited for my boyfriend to try it!

I had him try it out and he fell in LOVE! The shoulders were a bit of a tight fit, (he is kind of a bigger guy) He said it worked though because it pushed him back on the massager part and made the massage better.

This is a great chair! But if you don't have a couple of strapping young men available to help, get the white glove delivery, you will save yourself a lot of time, headache and backstrain. (Posted on 7/26/2019)
5 starsReview by Igor Z. on 5/15/2014
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. (Posted on 7/26/2019)
Very niceReview by Alexander D. on 4/2/2014
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. (Posted on 7/26/2019)
