QUICK SPECIFICATIONS
Source checked: Amazon-linked RELX Mars Pro manual. Specifications may change by revision or seller bundle; match the model name and product label before purchasing.
DETAILED OVERVIEW
The RELX Mars Pro is a 3D SL-track chair with unusually broad published fit limits: 4′9″–6′2″ and up to 330 pounds. The 53-inch track, automatic body scan, 12 automatic programs, three custom manual modes, 32 airbags, foot rollers, calf compression, and three zero-gravity levels make it suitable for mixed-size households.
Its main drawback is space documentation. The upright chair is already 66.02 inches deep, and the source does not publish full reclined dimensions or rear clearance.
WHO IT SUITS
FEATURE ANALYSIS
The 3D mechanism adds in/out pressure adjustment while the 53-inch SL-track continues beneath the seat. Automatic body scan helps establish shoulder position.
Thirty-two airbags cover the shoulders, arms, and legs with three pressure levels. Foot rollers and calf compression are separate from lower-back heat.
FIT AND ROOM PLANNING
The 4′9″–6′2″ range and 330-pound maximum make this one of the broadest shared-use specifications in the catalog. Each user still needs to verify shoulder, seat, calf, and foot placement.
At 29.84 inches wide and 192 pounds, the chair is manageable only with a planned delivery service. The 66.02-inch published depth is listed for the product, but the source does not provide the maximum reclined envelope or rear gap.
