QUICK SPECIFICATIONS
Source checked: KoziSense KZ-A18 manufacturer page and Amazon-linked manual. Specifications may change by revision or seller bundle; match the model name and product label before purchasing.
DETAILED OVERVIEW
The KoziSense KZ-A18 is a 3D, 50-inch SL-track chair that arrives fully assembled. It documents 12 automatic modes, body detection, three zero-gravity positions, a three-stage foot massager and lumbar/calf heat.
Its simple setup is appealing, but the source does not publish a user-height range, reclined dimensions, wall clearance, power rating or complete warranty terms.
WHO IT SUITS
FEATURE ANALYSIS
The 3D mechanism adds depth adjustment to a 50-inch SL-track. Automatic body detection helps position the program, and 12 modes provide preset variety.
A three-stage foot massager and adjustable calfrest handle the lower body. Air compression is documented at the shoulders, arms, calves and feet.
FIT AND ROOM PLANNING
The KZ-A18 is 50.9 × 30 × 42 inches upright, weighs 150 pounds and has a 250-pound maximum. No user-height range is published, so the adjustable calfrest should not be treated as proof of fit.
It arrives fully assembled in one box and is described for a 30-inch doorway. Confirm the carton dimensions, turns and final reclined envelope before checkout.
