The Osaki Pro has taken the art of the massage to new heights, implementing 4D technology along with other incredible new and innovative features. The Osaki Pro 4S chair is a product of Japan and is Osaki’s marquis product in the massage chair lineup. Come and experience the Osaki difference!

Superior 4D Massage Technology – Computer Body Scan

The advanced 2 ball massage head system moves on a vertical, horizontal and front and back plain. Before the start of every massage, the chair will accurately map the users back, analyzing the contours of back muscles and spine. This will ensure a more consistent massage pressure throughout the session, so that no area of back is neglected. Osaki has taken it a step forward, by adding a 4th dimension to its massage technology. Collaborating with professional massage therapists throughout Japan, Osaki has added speed variation to each style of massage. Much like the time test traditions of Japanese massage, the hands of the masseuse would slow down, accelerate or even pause to hold in particular areas. The Osaki Pro JP-4S is the most life like massage chair we have to offer.

Upper Shoulder Massage – Roller Extension

The 2 ball roller head system can retract and extend to about 5 inches, allowing to hit areas most typical chairs can’t reach. A common area where tensions and stress builds up is the upper part of the shoulders (upper Trapezius Muscle) which is connected to the back of the head through the neck. The rollers heads of this device will extend out to its maximum length above the shoulders and then firmly press down stretching the muscles.

Full Body Air Massage
Osaki has re-engineered it air massage technology, reducing the total airbags but increasing the surface area coverage. This reduces the stress on the air pump and valves, ultimately extending the longevity and dependability of this component.

Outer Shoulder Massager
Located on the upper sides of the backrest, there are 2 airbag massagers on each side. As the air bags inflate it will compress the shoulder inwards. The shoulder airbags may also inflate to hold you in place as the back rollers apply a soothing massage.

Hand & Arm Massager
As you insert your arms into the unique butterfly design, it will position the palm of the hands vertically. Simultaneously the hands and forearms will be massaged as the airbag inflates. The tapered design will contour the arms for an even massage.

Hip Massage
Along the sides of the seat, base are airbags on each side. As they inflate it will squeeze the hips.

Foot & Calf Massage
The calve massage is curved on the outer walls so that it will wrap around the calves as it inflates. There are also airbags on the back of the calves for a more complete massage. The feet are massaged by airbags which are lined the along the sides, pressing the feet down to the base of the foot massager.

Heated Backrest & Feet
The backrest with 2 heating pads, both located on both sides of the mid-upper back region. The gentle heat complements the effectiveness of the roller head massage. Located at the bottoms of the feet, the heat application is also mild which helps loosen the muscles and tissue along the arches.

Easy to Use Touch Screen Remote
Osaki Pro JP 4S has truly simplified the remote without losing any of the functions and controllability. Through the touch screen everything can be operated with a touch of a finger.

• 5 levels of air massage intensity. The air intensity can be individually set to your preference for 4 separate zones (the shoulders, arms, hips and feet).
• The back roller intensity can be set to 7 to 12 different intensity levels depending on the program.

    My husband has been having chronic back pain. Therefore, his chiropractor recommended that he get a massaging chair to help relieve the daily stress and pressure. We searched online and read all the reviews. This chair has great reviews and the overall best price.

    When it came to using the chair it seems to do a good job. While it doesn’t have the specific targeting that the much more expensive chairs do, the auto mode does a great job on relaxation and strong modes. The heater and vibration also work great.

    This is our first massage chair. I’m still getting accustomed to the features but I’m enjoying it as I go.

    The chair arrived in a huge box, I removed triple redundant layers of the highest quality cardboard, the inside layer covered in protective styrofoam over the plastic bags. Assembly was a breeze, the hose Luer locks take a strong hand to fully tighten, I fortified the blood pressure monitor style hosing sticking out between the backrest and base on the left side with flex split wire conduit. Be careful with the arm assembly, I stripped the thread off one of the bolts.The massage is very vigorous, I can see broken ribs in the osteoporotic preinstitutional, would avoid in this population. Both I and the 4 family members enjoy it greatly, we hope it will be our first and last massage chair. Japanese quality through and through, should hold 15-20 years.No regrets at all, especially for the deal I got.

    We bought this chair over six months ago, I wanted to wait some time before reviewing. I have to say the longer I own it, the MORE I love it! The chair targets those hard to get spots! I use this chair just about everyday, for pain relief, stress relief and plain old relaxation. Best purchase I have made in years!

    First of all it’s a great looking chair. We constantly get compliments on how stylish it looks. The chair is full of features and programs. It has worked wonders on my husband’s lower back and I myself use it simply as an indulgence. I’m sure it’s good for my posture and circulation and I have been sleeping better.

    I was never a big fan of these chairs but my wife insisted we get one. I can say w/o hesitation that it has been the best purchase we’ve ever made for a home “appliance” item. My wife who has a bad back loves it and even our children take turns using it.

    I have had a massage chair for about 15 years and it finally died. I loved that chair and didn’t think I’d find a replacement I liked. It is so relaxing. I use all the various programs depending on what the day has been like. Highly recommended.

    There are so many features and settings, but all of that are all satisfying. It also has new dimensional kneading techniques that gives a new dimensional massage. It’s really great! No more to ask.

    Has the new double sensing system, triple modes for air massage an double heater. Does a great job on the back – use it almost every day. You can watch TV in this thing and fall asleep. Fairly compact too.

    It’s good that I bought this chair, it is really good and it’s seriously amazing! It would go nice in any room of the house and not look out of place as a massage chair and what I like about is the remote was very easy to use and know what part of the body to choose because you could just click on that area on the remote. It’s really awesome.
