Infinity Riage 4D

Infinity pitches the Riage 4D as its technology showcase, and the mechanism is the reason: a 4D back-and-glutes roller that moves up-down, left-right, and in-out, with variable speed as the fourth dimension, all adjustable by the user. It rides an L-track and is joined by two levels of zero-gravity recline, TrueFit body scanning, lumbar heat, airbag compression, calf kneading rollers, and dual reflexology foot rollers. Ten choreographed auto programs run from a menu-driven TFT LCD remote plus a quick-access panel on the chair, and headrest-mounted Bluetooth speakers carry Infinity's SootheMe nature-sound programs. Zero Wall Fit technology slides the chair forward as it reclines, so the 69-inch reclined length needs only a few inches of rear clearance.

At $8,999.00 the Riage 4D undercuts Japanese-made 4D flagships meaningfully while keeping the feature that matters most, though the value math depends on reading Infinity Care closely: five years on the frame, three on parts, but complete in-home parts-and-labor coverage for just the first year, with paid upgrades to extend labor. Heat is lumbar-only, and the product page carries a Limited Availability flag, so stock may not last. Fit runs 59 to 74 inches and 300 lbs, in black or dove brown.
