iRest’s SL-type design is specially crafted to accommodate the unique body shapes and sizes of all users, ensuring a comfortable and personalised massage experience.

Our innovative SL-type combination is designed to accommodate all curves from the user’s spine to the hip, providing a comprehensive and personalized massage experience. In contrast, low-priced massage chairs on the market often have only one function of S-type or L-type, which reduces production costs. Massage chairs that lack SL-type technology cannot provide an accurate and safe massage, as each person’s body shape has unique curves.

When purchasing a massage chair, it’s essential to ensure that it has SL-type technology to ensure a comfortable and effective massage that meets your body’s needs.

iRest is dedicated to providing only high-quality SL-type technology in all of its products.

The S-type function in a massage chair refers to the curve of the spine, while the L-type function refers to the shape of the body when seated. If a massage chair is designed with only the S-type function, it can significantly reduce the effectiveness of lower body massage. Similarly, if it is designed with only the L-type function, it cannot follow the curves of the spine, resulting in areas where massage cannot be performed. This limited movement only allows for a simple up-and-down motion from the neck to the hips, greatly reducing its effectiveness.

I experienced a new world I had never known before! How can it be so cool to get a massage on the back to hips!? When I get the massage, the feeling is different from the pain. Always receive very cool massage even in areas that I could not reach with my hands.”

The perfect combination of iRest’s SL technology and 3D(4D) roller massage technology

All of iRest’s massage chairs are equipped with high-quality SL-type technology, which is seamlessly integrated with iRest’s delicate roller massage technology to provide the best possible massage experience. The SL-type technology responds to the user’s body flexion, while the roller massage technology simulates the effect of receiving a direct massage from a professional masseuse. Together, they create a responsive and effective massage experience that can be enjoyed at any time.

Best harmony [SL-type + 3D(4D) roller massage + Zero Gravity]

From the moment you sit down, iRest’s massage chair makes you feel special. The SL-type technology enables massaging every corner of your body, while the 3D (4D) roller massager simulates the effect of a direct massage from a professional masseuse. Moreover, the Zero Gravity feature minimises joint strain caused by gravity, allowing for a smooth full-body massage that follows the curves of your body in the most comfortable position possible in the massage chair.
