Product Overview

The OS-Pro 4D Emperor by Osaki is where style, luxury, and the newest massage technology come together to give you the best chair massage experience possible. The 4D L-track massage design has been updated for wider, deeper, and more precise massage, with 20 massage settings that we’ll dive into deeper later on. Every detail of the chair’s design was intentionally crafted using the highest quality materials to give the OS-Pro 4D Emperor its super stylish appearance, while still maintaining all of the massage functionality that Osaki is so well known for.

Massage Quality

The massage quality of the OS-Pro 4D Emperor is some of the best we’ve seen among 4D massage chairs with similar price ranges. The updated L-track design we mentioned earlier covers more surface area and precision than conventional massage rollers. It actually combines S and L track technology that gives you close to 50% more massage area than average S-track chairs.

It has 20 different massage programs that are divided into 4 different categories, including Neck and Shoulder, Lower Back, Manual and Advanced. Combine this with 8 different levels of 4D massage intensity and 5 levels of air massage intensity from 18 highly advanced airbags, and you have seemingly endless possibilities of massage combinations for customized relief and comfort. Plus, the Emperor also has an all-new Calf, Bridge, Knee, and Heel Massage section on the upper part of the leg rest that works every bit of stress out of your lower extremities, stretching and massaging all the way down to the heel of the foot.

Technology Features

The OS-Pro 4D Emperor comes decked out with some of the latest features in massage chair technology. The Body Scan feature uses intuitive scanning technology that detects your shoulder height and maps out the areas in your neck and back where massage pressure is most needed. The footrest has an automated extension that extends out and back during the scan to get precise measurements of your legs, and it adjusts accordingly based on the feedback it receives.

The audio speakers in the headrest are Osaki’s highest grade. They use Bluetooth for instant connection to your wireless devices, and the Amphitheater sound system blocks out surrounding noise. All of this can be controlled with the upgraded Touch Screen Remote Tablet.

With its easy-view display screen, you can monitor and adjust all of your settings in one place. Lastly, the Osaki designers used space-saving technology to bring you the perfect massage chair, while still maximizing your living space.

Therapeutic Benefits

The therapeutic benefits of the Emperor can be seen in the numerous available massage programs that make it easy for you to find the perfect relief for your tight and sore muscles. In addition to therapeutic massage features, you can also benefit from using either of the 2 stages of zero gravity for weightless-like massages that reduce spine and joint pressure by distributing your weight more evenly. If that wasn’t enough, the Emperor comes with the most advanced back heating system. It uses mild infrared heat to penetrate deeper than traditional thermal heat, giving you the healing power of heat from your neck, all the way down to your hamstrings.

The Osaki OS-Pro 4D Emperor comes with a basic 3-year manufacturer’s warranty that covers parts and labor. This should cover just about anything that might happen to malfunction during that time. Osaki is known for building some of the world’s best 4D massage chairs. Their reputation for having outstanding craftsmanship and for making massage chairs that last is enough for us to rate it 4 out of 5 stars when it comes to durability.

As far as pricing goes, the Emperor comes with a fairly hefty retail price tag of $9,499. Obviously, it’s not the most practical chair if you are on a tight budget, but it is clearly worth the investment considering all of the advanced features the Emperor has to offer.
