Massage Chairs Reach a New Level of Professional Recognition as GrandMaster Jack Lee and World Massage Champion Evaluate ZERO’s ROBOZEN Series

ZERO Healthcare is taking professional validation of massage chair technology to a new level by bringing together two experts from different fields to evaluate its latest ZERO ROBOZEN massage chair series. Traditional bone alignment and meridian therapy expert GrandMaster Jack Lee and World Massage Champion Sim Zher were invited to assess the series from their respective professional perspectives, examining how closely its massage performance reflects human body mechanics, professional massage techniques and therapeutic principles.

With decades of experience in traditional bone alignment and meridian therapy, GrandMaster Jack Lee brings extensive hands-on knowledge of the human body and common concerns such as neck stiffness, shoulder tension, lower back fatigue and poor circulation in the lower limbs. Meanwhile, Sim Zher is an internationally recognised professional massage therapist who was crowned Double Champion at the 2026 Southeast Asia Massage Championship (SEAMC) and also won an international championship organised by the World Massage Federation in the Philippines. Her expertise covers professional massage techniques and musculoskeletal anatomy.

Rather than evaluating the massage chairs solely based on comfort or intensity, both experts examined the ZERO ROBOZEN series according to professional standards. GrandMaster Jack Lee highlighted that an effective massage experience should focus on accurately targeting key pressure points while delivering appropriate pressure and rhythm, rather than simply relying on stronger intensity. Sim Zher similarly explained that professional massage involves precision, rhythm, coverage and continuity, with movements that follow the natural direction of muscle fibres and maintain smooth transitions between different areas of the body.

One of the key highlights of the evaluation was ZERO ROBOZEN’s Foot Arch Stretch technology. The experts noted the importance of the feet, ankles and calves, which can often be overlooked despite their role in movement, balance and overall body support. GrandMaster Jack Lee described the feet as the foundation of the body, while Sim Zher pointed out that the foot arch and calf muscles are important areas in both professional massage and sports recovery. By incorporating these concepts into a massage chair, the technology aims to provide users with a more comprehensive relaxation and massage experience.

World Massage Champion Sim Zher shared that international massage competitions are evaluated based on far more than massage strength. Judges assess whether massage movements follow the natural direction of muscle fibres, maintain smooth transitions, deliver precise pressure control and ensure seamless flow across different body regions. Sim Zher said, “Professional massage is never just about force, it is about precision, rhythm, coverage and continuity. A quality massage chair should embody these same principles.”

The collaboration also reflects ZERO Healthcare’s approach to professional product evaluation. According to the company, the involvement of GrandMaster Jack Lee and Sim Zher was not intended as a conventional celebrity endorsement, but as an opportunity to obtain professional perspectives on the design and performance of its massage chair technology. Tommy Tham, Founder and Managing Director of ZERO Healthcare, emphasised that technology should not replace professional massage therapists, but instead help extend the benefits of professional massage experiences into more homes in a convenient and accessible way.

As consumers increasingly prioritise preventive healthcare and home wellness, ZERO Healthcare believes that the future of massage chair innovation should focus on more than simply adding features. Instead, the company aims to develop technologies that better reflect human anatomy and professional massage principles, while offering users a more meaningful wellness experience at home.

ZERO Healthcare also revealed plans to expand its professional evaluation initiative by inviting experts from various disciplines, including world massage champions, experienced massage practitioners, physiotherapists, chiropractors and sports rehabilitation specialists, to participate in future product assessments and professional knowledge exchanges.

The public experienced the ZERO ROBOZEN massage chair series during the launch event, including its world’s first Foot Arch Stretch technology, which was recognised by massage experts for extending professional massage concepts into everyday home wellness.

Through these cross-disciplinary collaborations, ZERO Healthcare hopes to contribute towards a more professional evaluation framework for the massage chair industry. The initiative aims to encourage consumers to consider not only product features and pricing, but also the professional principles and technologies behind the design of each massage chair.

With the ZERO ROBOZEN series serving as the latest platform for professional assessment, ZERO Healthcare is positioning expert evaluation as an important part of its approach to product development and innovation. The company believes that a truly exceptional massage chair should go beyond delivering comfort by earning the trust and recognition of professionals across relevant fields.
