Infinity Massage Chair
Founded in 2009 and based in Seabrook, New Hampshire, Infinity is a U.S.-based massage chair company known for delivering high-spec chairs with sleek design and a therapeutic edge. Unlike import-only brands, Infinity blends in-house product design and engineering with outsourced ISO-certified assembly, primarily in China. What sets the brand apart is its focus on stretching mechanics, wellness-focused features, and a steady push toward innovation (such as the Flex-Track® system and dual-roller Syner-D™ technology).
The brand also holds an A+ BBB rating, operates its own U.S. service and parts network, and positions itself just under the ultra-luxury tier—competing with the likes of Human Touch and Osaki Maestro on tech, while often beating them on warranty terms and structural comfort.
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.
