Osaki Massage Chair
Osaki is a major U.S. massage chair brand operating under Titan World LLC, with its headquarters and parts distribution center based in Texas. The brand is known for aggressively covering the full price spectrum—from compact 2D chairs like the OS-Champ to high-end 4D models like the Maestro LE 2.0. Osaki uses a hybrid approach to production: roller design and core mechanics are developed in Japan, while manufacturing is outsourced to Chinese factories. The result is a product line that packs sophisticated hardware at relatively lower prices—though occasionally at the cost of consistency in support and finish.
Osaki’s reach is wide: you’ll find its chairs at Costco, Amazon, and across nearly every massage chair dealer in the U.S. But popularity doesn’t always mean perfection—and as this review shows, Osaki shines in some areas while showing its seams in others.
Kahuna Massage Chair
Kahuna, owned by AJX Distribution Inc. in California, began in 2013 as an Amazon-first brand and rapidly grew into one of the most visible names in the U.S. massage chair space. Its claim to fame is performance-driven chairs with aggressive pricing, particularly in the $1,500–$5,000 range.
While the brand lacks a luxury polish and isn't accredited by the BBB, it compensates with an extensive lineup, surprising feature density, and chairs that frequently appear at the top of Amazon’s bestseller lists. Kahuna engineers its chairs in-house, builds them in ISO-certified facilities in Asia, and handles warranty and parts from California. For users focused on value, stretch, and long tracks, it's an appealing contender—though refinement takes a back seat to performance.
