Technical specificationsAs we’ve already mentioned, this product is made 100% in Japan and it’s extremely powerful due to the 4 built-in motors that help it run every time you turn it on. Additionally, the various rollers provide a human-like massage, having a length of 31 inches and featuring an S-track type. Here we also have to mention the fact that the rollers have a depth and intensity adjustment, all for making you receive a soothing massage experience.
Massage featuresWe have to admit we were truly impressed by the many massage features of this chair, being one of the most versatile models on the market. The 4D roller mechanism features 2 rollers on each side of the spine. The rollers are quite remarkable as they can easily move 12.5 cm forward and back while featuring a 12-position adjustment, for various massage depths. Also, it includes a 2-ball massage head system that has a three-dimensional movement which goes in and out, being able to travel 5 inches in depth for a more intense massaging session in the upper shoulder area where most massage chairs can’t get. The rollers technology used in manufacturing this massaging chair is the most advanced one available at this moment. Furthermore, it features 34 airbags, being able to reach the areas that rollers don’t, providing a full body compression massage for feet and calves, hands, and arms, shoulders, hip and thighs. As a result, the entire body will be well taken care of, enabling the blood circulation for the most important zones that usually accumulate a lot of tension. The special hands and arms area allow you to position the palms vertically, and both hands and arms will be massaged when the air bag inflates. Additionally, the shoulder area has 2 airbags which combined with the rollers provide an intense alleviating massaging session. The hip area also is equipped with airbags on each side, so you will feel the hips squeezed every time the airbags expand. On the calves area, the airbags are placed on the back, so you will receive a full massage of this area, while the foot airbags are placed along the sides, being pressed towards the base of the sole acupressure balls.
Programs and massage techniquesAs about the massage techniques, the chair features 41 different kneading massage techniques with more than a hundred massage combinations, so you can customize your session according to your preferences. Also, it comes with more than 20 programs divided into three categories: 7-minute, 16-minute, and 30-minutes course auto programs. The first category includes massage for the neck, shoulder, shoulder blade, waist and sciatic. From the second category you can choose a whole body, neck and shoulder, waist, stretch or you can create and memorize your own program. The 30-minutes course auto programs allow you to choose from a VIP course, sommelier course, slow stretch or air relaxation program. In what concerns the stretching programs, the model provides various stretching modes that target the neck, shoulder, waist, knee and feet, thus relieving the joint pain. The Triple Mode Air System offers therapeutic massage for aching muscles and improves the blood circulation, allowing you to choose one of the 3 available modes: knead, pulse, and normal.

Complementary therapiesFor a more intense massage therapy, the Premium 4S includes a double heat therapy for the low back and the bottoms of the feet. The heat pads do an extremely great job because they warm up the two regions in order to provide a more therapeutic massaging session. The result is that all the accumulated tension will be removed, thus making you feel much better. Unfortunately, it doesn’t feature chromotherapy lights, but this will not influence its performance.
Convenience featuresBecause it’s specially made to offer one of the best massages for all those who use it, the manufacturer also though at the comfort of the user. Therefore, the model features a fully automatic leg extension, so you can conveniently extend, raise, or retract the leg rest with the help of the included remote control. Also, we have to mention the automatic recline which can place it in a line flat position, which is quite helpful for the spine due to the fact it helps take the pressure off this region. Additionally, the model has a full-color touch panel so you can easily control the many options offered by the chair. Therefore, with a simple touch of the screen, you can get one of the greatest massage experience. Additionally, the 4S includes a double sensing body scan, so once you sit in the chair, it will automatically detect your acupoints along the back, placing the rollers and their depth so you can receive an efficient back massage.
