Two brands anchor our premium massage chair lineup: Infinity and Kyota. Both build excellent chairs, and both offer 4D and dual-mechanism technology. But each lineup has its own strengths, and knowing those differences is the key to choosing the right chair.
We compared both lineups model by model. Here's our honest breakdown.
The 30-Second Version
If stretching, decompression and inversion are your top priorities, start with Infinity. If you want long L-Track coverage, more model choices and hands-free voice control, start with Kyota.

Lineups at a Glance
Infinity focuses on a tight lineup of three new chairs: the IT-8500 Plus, the Smart Chair X3 4D and the Dynasty 4D. Each one leans into a clear specialty, from deep-tissue decompression to a full sensory experience.
Kyota offers a wider range, from the 4-node Zenyu M338 up to the Syner-D Nokori M980. In between sit five 4D chairs (Yugana, Hatsumei, Joubu, Yutaka and Kansha) at different price points. If you want to fine-tune features against budget, Kyota gives you more steps on the ladder.
Massage Technology
Both brands use advanced roller systems, but the emphasis differs:
Infinity's Approach: Stretch and Decompress
The IT-8500 Plus and Smart Chair X3 both use a near-flat reclining S-Track that reaches true inversion. A Decompression Stretch and Waist Twist Therapy work alongside it. The S-Track follows the S-curve of your spine from neck to lower back, and the X3 adds 3D/4D deep-tissue rollers with TrueFit Body Scanning.
The Dynasty 4D takes a different path. Its 4D mechanism runs from neck and shoulders to glutes, with TrueFit scanning in the back and legs, chromotherapy and SootheMe sound therapy for a full sensory experience.
Kyota's Approach: Coverage and Choice
Kyota leans into L-Track length. The Joubu M880 has a 53" L-Track, and the Yutaka M898 a 49" L-Track. Both cover neck to glutes. The Hatsumei M900 adds an AI Custom Massage Generator. At the top, the Nokori M980 uses Syner-D dual mechanisms on a J-Track/Flex-Track for coordinated back and glute work.
The difference comes down to emphasis. Infinity's new chairs are built around stretching and decompression. Kyota's are built around coverage and customization. Both are valid; it depends on what your body needs.
Zero Gravity & Space
Both lineups include zero-gravity recline. Examples include the Infinity Smart Chair X3's Weightless Zero Gravity Recline and the Kyota Genki M380's Weightless Zero Gravity Recline. For tighter rooms, Zero Wall Fit needs just 2" of wall clearance. It's on the Infinity Dynasty 4D and on most Kyota models, including the Genki, Hatsumei, Kansha, Yugana and Yutaka.
Smart Features & Connectivity
Kyota generally leads here. Intelligent Voice Command + Control appears on the Genki M380, Yugana M780, Kansha M878, Joubu M880 and Zenyu M338. The Joubu adds a 7" touch-screen tablet with 24 auto programs and Bluetooth speakers.
Infinity has its own highlights. The IT-8500 Plus offers app control from your phone plus Bluetooth speakers, and the Dynasty 4D includes a wireless charging pad. If hands-free control matters most, Kyota has the edge. If you prefer app control or a simpler experience, Infinity is a great fit.
