RELX Mars Pro Full Body Massage Chair, Zero Gravity, 53 in SL Track, Body Scan, Heat, AI Voice Control, Black

The RELX Mars Pro (Elite) is a full-body massage chair built around shiatsu rollers that travel a 53.15-inch SL-shaped track from the neck down the back and under the seat to the hips and thighs, with five speed levels and five back-width settings. A body scan at the start of each session detects shoulder position and back width and adjusts the roller path to match, and a one-touch reset returns the chair to upright. Massage runs as one of 15 automatic programs or as one of five manual modes (upper body, lower body, full body, fixed spot, or partial zone) using five techniques: shiatsu, kneading, beating, knead-and-pat, and knocking.

Thirty-two airbags at the shoulders, arms, legs, and feet apply compression at five pressure levels, with the foot airbags wrapping the feet from all sides. Far-infrared heating panels warm the lower back and the calves. In the footrest, foot rollers with three intensity levels work the soles beneath the airbags, and the calfrest extends 7.8 inches to match leg length for users from 4 feet 9 to 6 feet 2. A yoga stretch function holds the body with the airbags while the legrest lowers and the backrest reclines.

Three zero-gravity stages (initial, comfort, and deep) progressively raise the legs to and above heart level, and the backrest, legrest, and linked recline can each be adjusted independently, with 28 degrees of backrest travel and 80 degrees of legrest travel. Controls are on a tablet-style HD touchscreen mounted on a flexible arm beside the seat, with a home screen of Auto, Manual, Position, and Auxiliary menus, a session timer, and a language setting, plus AI voice control that responds to spoken commands and can be switched off. The chair includes a Bluetooth speaker with surround sound in the headrest, a USB port, an LED accent light, and dedicated switches for Bluetooth, voice control, and lighting. Upholstery is synthetic leather in black with diamond-quilted seat and back inserts and silver trim on the side panels and armrests.
