I work in seating ergonomics, and gaming chairs are the category where marketing and biomechanics diverge most sharply. Bucket seats, racing stripes and "premium PU" tell you almost nothing about whether a chair will support a body for eight hours. What does tell you something is adjustment range — and the AutoFull M6 Ultra+ 2.0 Shiatsu Massage Gaming Chair publishes more of those numbers than most of its competitors combined.

The Features That Earn Their Place
Dynamic tracking lumbar support is the real story
Most gaming chairs treat lumbar support as a pillow you strap on. AutoFull's adaptive system moves up, down and forward, which means the support point follows the change in your pelvic angle as you shift between an upright working posture and a reclined gaming one. That is the single most meaningful ergonomic difference between this chair and a €300 bucket seat, and it is the feature I would pay for.
Climate control is not a gimmick in a sealed room
Two high-powered fans bring the seat down to 66.2°F, and graphite heating elements take it up to 122°F, with three levels either way. Anyone who has spent a summer evening on a PU-upholstered chair knows why the cooling side matters — heat and moisture build-up at the seat pan is a genuine comfort limiter, not a luxury complaint. The heating side is equally practical in a cold home office in January.

The armrest adjustment range is unusually complete
360° rotation on the main shaft, 40° of inward and outward angle on the secondary shaft, 3.54 inches of height and 2.75 inches of depth, plus a 20° fold-up. In practice this is what lets you set the armrest to actually carry forearm weight at your keyboard height instead of hovering uselessly beside you. Shoulder and neck load in long sessions is driven by exactly this adjustment, and most chairs under-deliver on it.
A 3D headrest that adjusts independently on both sides
Independent left and right support with 60° of angle adjustment, 1.25 inches of orbital travel and 4 inches of vertical adjustment is a serious headrest specification. It is aimed at users between 5'3" and 6'4", which is a wide but not unlimited band.
Four Honest Drawbacks
1. €899.99 is a lot of chair, and the cheaper sibling is very close
The M6 Ultra 2.0 with vibration massage sits at €599.99. That is a €300 gap for the step up to shiatsu massage. Vibration massage is already included in the lumbar support of the Ultra+ via two high-frequency motors, so you need to genuinely want the shiatsu mechanism to justify the premium.
2. Massage functions in a chair are a comfort feature, not a therapy
I want to be plain about this because the category oversells it: built-in massage in an office or gaming chair is pleasant and can help you notice tension, but it is not a substitute for standing up, changing posture, or clinical treatment for back pain. If you are buying primarily to manage an existing back problem, spend the money on the adjustability and treat the massage as a bonus.
3. Powered features mean cables, weight and more to go wrong
Fans, graphite heaters and massage motors all need power. That means a chair tethered to an outlet, more mass to move, and more components that can eventually fail than in a purely mechanical seat. A chair with no electronics has a much simpler long-term ownership story.
4. The height band excludes people at both ends
AutoFull specifies effective neck support for users between 5'3" and 6'4". If you are shorter or taller than that range, the headrest geometry is designed around someone else, and no amount of adjustment fully compensates for a seat pan and backrest scaled to a different body.
Who Should Buy It
- People who sit for six-plus hours a day and will actually use the dynamic lumbar tracking and full armrest range.
- Anyone in a room that runs hot or cold — the climate control genuinely changes long-session comfort.
- Users between 5'3" and 6'4" who want a headrest that can be dialled in precisely.
- Buyers who want one chair for both work and gaming rather than a compromise on either.
Who Should Not
- Budget-conscious buyers — the M6 Ultra 2.0 at €599.99 delivers the core ergonomics for €300 less.
- People outside the 5'3"–6'4" range.
- Anyone who wants a chair with nothing to break — a good mechanical task chair is the more durable long-term bet.
- Buyers hoping to treat chronic back pain with a purchase. See a clinician first; buy the chair second.
Verdict
The AutoFull M6 Ultra+ 2.0 is one of the better-specified chairs in the gaming category, and unusually, its best features are the boring ergonomic ones rather than the massage headline. Dynamic tracking lumbar support, a genuinely comprehensive armrest adjustment range and a 3D headrest with independent sides are the reasons to consider it. Climate control from 66.2°F to 122°F is the feature you will appreciate most on the days you did not think you needed it. At €899.99 against a €999.99 regular price it is a premium purchase, and the €599.99 M6 Ultra 2.0 is a serious internal competitor. Choose the Ultra+ if the shiatsu mechanism is something you will use weekly; otherwise the money is better spent elsewhere in your setup.
