Category Architecture
When you provide massage chair models or brand lists, each review is automatically slotted into one or more of these four primary hubs.

Chairs engineered with variable-speed, variable-protrusion rollers for cervical, thoracic, and lumbar fascia release.

Comparing continuous L-track rails against articulated split-track frames that allow independent back and leg recline.

Models featuring forward-gliding rails that require less than 10 cm of rear wall clearance and pass through standard residential doors.

Dedicated evaluation of shoulder airbag height limits, motorized calf extension travel, and neck roller alignment for outlier statures.
