Main Distinguishing Features

The Osaki OS-Pro 4D Emperor Massage Chair is one of the best massage chairs with advanced features that make it stand out from other massage chairs in the market. Here are some of the main features that set it apart:

4D Advanced Massage

The newly enhanced 4D L-track massage is designed to massage wider, deeper, and more precisely than the conventional massage rollers. The 4D massage technology will mimic the hands of a professional masseur. The OS-Pro 4D Emperor offers 8 different levels of 4D intensity. With the variety of adjustment levels, such as 5 levels of air massage intensity and speed of the rollers.

Ergonomic SL-Track Massage

The Emperor combines both the S and L track technology for an exceptional massage experience. The S-Track rollers will contour the natural curvature of your spine. The L-Track extends from your neck, all the way down past your lower back, and finally wraps underneath the back of your thighs. The L-Track offers about 50% more massage area than your average S-Track chair.

2 Stage Zero Gravity

The Emperor is equipped with 2 stages of zero gravity, giving the user a weightless feeling during the massage. This gives the user an option on how far back they want their chair to recline automatically, or you can adjust the chair manually with the remote. Inspired by NASA, the Zero Gravity is to help reduce the stress on the back, evenly distributing the weight and pressure.

Heated Back Roller Massage

The OS-Pro 4D Emperor has the most advanced back heating system. The roller itself will heat up acting like hot stones massaging at the same time. The heated back roller allows for a far greater surface heating area, From the neck down to the hamstrings. It applies an infrared heat which is deep penetrating compared to traditional thermal heat with high temperatures. The warm heat will complement the massage in loosening the muscles.

Air Massage (18 Airbags)

There are multiple airbags located throughout the massage chair to offer a full-body massage experience. The Osaki Pro Emperor offers a total of 18 highly advanced airbags in the massage chair.  Airbags are located at the shoulders, arms, waist and pelvis, and calf areas. The total airbags have been reduced but cover more surface area than previous technology with far greater efficiency and reliability, overall experience. 

Adjustable Shoulder Massage

Regardless of body type, the adjustable shoulder massager can be easily tightened by pushing the massager inwards. There are 3 adjustable sizes on each side. To reset to the default width, simply push in all the way on both sides and it will release.

Calf Kneading

On the upper section of the Osaki Pro Emperor's leg rest, the air massagers will rotate in a circular motion to add a new dimension to the calf massage. For the foot portion addition components have been added to stretch and massage the bridge and heel of the foot. The experience is pretty incredible.

Foot Kneading

Underneath the feet of the Osaki Pro Emperor there are spinning reflexology rollers to provide an outstanding foot massage. The rollers under the feet will travel along the sides and arches of your feet to provide a more dimensional kneading experience.

Auto Extendable Footrest

The footrest of the Osaki Pro 4D Emperor will extend outwards and then retract inwards when scanning the length of the user’s legs. Simply apply pressure with your feet when the length is at the desired position in order to set the position.  The remote also allows you to auto-adjust the leg rest to either extend or retract.

Space Saving

The Osaki OS-Pro 4D Emperor Massage Chair only needs 4.7” from the backrest to the wall, which reduces the amount of space the chair takes up. Space-saving design allows you to maximize your valuable living space.

USB Charger & Wireless Charger

The Emperor 4D was thoughtfully designed with a wireless charger for the modern times of digital devices. The user can charge their smartphone on the wireless charging pad located at the top of the armrest. Please note, the wireless charger is only available with wireless charging capability.

Quick Controls

The Osaki Pro 4D Emperor Massage chair was designed to have easy access to control the chair without using a remote tablet by using the super convenient fingertip controls. The user can adjust the 4D intensity, recline positions, Zero Gravity, Auto massage program and Heat function.

Q: What is the assembly like?

A: The Osaki OS-Pro 4D Emperor Massage Chair requires some assembly, but it comes with a clear instruction manual and all the necessary tools. The set-up can be completed fast if you are skilled at putting furniture together. You’ll first unbox the chair and begin by taking out the main body.  Next, you will attach the side panels.
