DOCUMENTATION-BASED PRODUCT REVIEW
MassaMAX MT398
Model: MT398
The MT398 is built for buyers who want 4D control, stretching and three zero-gravity positions. The chair itself is well specified, but fit and room planning are harder because height, capacity and reclined dimensions are not published.

DETAILED OVERVIEW
What this chair does
The MT398 is aimed at someone who wants more control over the massage itself, including 4D adjustment, stretching and three zero-gravity positions. The chair is less helpful about the basics of fit and placement, so it requires more pre-purchase confirmation than its feature list suggests.
The weak point is fit documentation: the available manual does not publish a user-height range, maximum load, reclined size, rear clearance or carton dimensions.
WHO IT SUITS
Who is the MT398 best for?
Buyers prioritizing 4D control and stretching programs
Shoppers who want lumbar/calf heat and foot rollers

FIT AND ROOM PLANNING
What the measurements mean
MassaMAX does not publish a user-height range or maximum load in the material used for this review. The upright dimensions and chair weight are known, but body fit, reclined room size and wall clearance remain open questions.
The footrest and controller require connections after delivery. Ask for carton size, reclined size, required wall gap and route guidance before ordering.
