Massage-chair class planner
Households choosing a massage chair. The decision this page isolates is narrow on purpose: translate body length into a massage-chair class. Fit and capacity are the expensive mistakes. Settle those before you commit to a finish or a brand.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Osaki, Kahuna, and Real Relax. It produces an explainable class so Osaki OS-4D Pro Maestro, Kahuna LM-6800, and Real Relax Favor-03 can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in CTA. This page does not quote a price or rank a brand.
