The details real buyers ask about before they order, pulled straight from our support inbox.
QWhat are the dimensions of the M616, and how much floor space should I plan for?
A
The M616 measures 75cm (W) x 105cm (D) x 165cm (H) in its upright position. Because the backrest and footrest extend outward during recline, we recommend leaving extra room in front of and behind the chair for full extension.
QDoes the massage track adjust to different body types, or is it a fixed pattern?
A
Yes. Body Shape Detection scans your back before the session to map the massage path to your spine curve, and the SL-track then runs an 80cm stroke with a 4-15cm adjustable width to follow your shoulders and hips.
QHow strong is the massage - can it be adjusted for something gentler?
A
The chair runs on the Master 3rd Generation Controller, which adjusts intensity across the full-body airbag system and rollers, so sessions can range from a light relaxing mode to a firmer, deep-tissue feel.
QWhat does the torque suspension actually do for comfort?
A
It lets the backrest track adapt to your spine's natural curve as it moves vertically, while spring steel buffering absorbs left-right overload, keeping the rollers tracking smoothly instead of jabbing at fixed points.
QCan I control the chair with my voice instead of the panel?
A
Yes, the M616 supports 13 AI voice commands through a microphone built into the shortcut keys, so you can start programs, adjust intensity, or recline without picking up the remote.
QIs there a speaker in the chair, or do I need external speakers for music?
A
It has a built-in Bluetooth speaker, so you can pair your phone directly and play music or a podcast through the chair during your session.
QWhich parts of the body get heat therapy?
A
Heat therapy is built into the waist, back, and calf zones, and can be used on its own or alongside the massage program for extra warmth and recovery.
QWhat's covered under the warranty?
A
Every M616 includes a 3-year limited warranty, covering the mechanism and electronics against manufacturing defects under normal home use.
QDoes delivery include setup, or do I need to assemble it myself?
A
Every order ships with free curbside delivery, and white-glove in-room setup can be added at checkout, so the team places and sets up the chair for you instead of leaving it boxed at your door.
QWhat does the Negative Ion Function do?
A
It releases negative ions during your session to help freshen the air around the chair - a small wellness touch alongside the massage itself, not a replacement for ventilation.
