Model: Mars Pro

DETAILED OVERVIEW

What this chair does

The Mars Pro was built for a household with users of different sizes, pairing a 4′9″–6′2″ range with a 330-pound maximum. Its 3D SL-track, foot rollers and three zero-gravity levels are appealing, but the chair is long even before the missing reclined measurement is considered.

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

Who is the Mars Pro best for?

Households spanning short and average-to-tall users
Buyers needing a published 330-pound maximum
Shoppers wanting 3D depth, three zero-gravity levels, and foot rollers
Homes with room for a long 66-inch upright footprint

FEATURE ANALYSIS

How its main features work

3D massage and 53-inch SL-track

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.

  • 12 automatic programs
  • Three custom manual modes
  • Automatic body scan

Air, feet, heat, voice, and audio

Thirty-two airbags cover the shoulders, arms, and legs with three pressure levels. Foot rollers and calf compression are separate from lower-back heat.

  • Three zero-gravity levels
  • AI voice control and Bluetooth speakers
  • Yoga stretching

FIT AND ROOM PLANNING

What the measurements mean

The broad published range makes the chair easier to shortlist for shared use. Each person still needs to check shoulder, seat, calf and foot placement, and the room needs more confirmation because the full reclined envelope is not published.

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.

DELIVERY AND SETUP

Will it reach the room?

Start with the route: 192 lb chair; confirm cartons and service level. The chair itself weighs 192 lb. For setup, confirm with current Amazon listing. Measure every doorway, turn, stair and landing, then confirm whether delivery is curbside, threshold, room-of-choice or white glove.

WARRANTY AND SUPPORT

Who supports the chair?

The Amazon-linked manual states a 3-year limited guarantee. It does not provide a detailed parts, labor, structural, or in-home-service schedule in the extracted text.

The manual directs buyers to customer service through Amazon or the provided after-sales contact. Confirm that contact on the live listing.
