I assess seating for a living — office chairs, task chairs, and increasingly the gaming chairs that have quietly become the default desk chair for anyone under thirty. The category has a reputation problem it mostly earned: bucket seats borrowed from cars, fixed lumbar bolsters that fight the spine, and feature lists heavy on RGB and light on adjustment.
The AutoFull M6 Ultra+ 2.0 is trying to argue its way out of that reputation with engineering rather than aesthetics. It is the official chair of IEM 2026 and carries shiatsu massage, active seat heating and cooling, and a lumbar system that moves in four directions, at €899.99 down from €999.99 on AutoFull’s European store. Whether that is a serious ergonomic chair or a very well-equipped novelty is worth working through carefully.

Nine hundred euros puts this chair in direct competition with established ergonomic office seating rather than with other gaming chairs, which is the comparison that matters. Current pricing and the cheaper vibration-massage variant are on the official AutoFull EU store.
What the M6 Ultra+ 2.0 gets right
Dynamic tracking lumbar support is the real headline
Most gaming chairs give you a lumbar pillow on a strap. AutoFull’s system moves up, down, forward and back, adjusts by knob and locks in position. That four-way adjustment is what proper task chairs offer, and it matters because lumbar support that sits at the wrong height is worse than none at all — it pushes the spine into a curve it does not want. Being able to place the support at your actual lordotic curve, then lock it, is the single most valuable feature on this chair.
Active climate control is unusual and genuinely useful
Dual fans cooling the seat to 66.2°F and graphite heating to 122°F, across three levels, addresses the most common complaint about padded gaming chairs: they trap heat. Anyone who has sat through a summer session on a PU-covered seat knows the problem. This is a feature borrowed from premium car seats, and it belongs here more obviously than it belongs in a car.
The headrest is properly adjustable, not decorative
A 60° angle range, 1.25 inches of forward and back orbital movement and 4 inches of vertical travel is a real adjustment envelope. Most gaming chair "neck pillows" are a strap-on cushion that sits wherever gravity leaves it. Independent support adjustment on both sides is a thoughtful addition for people who read or watch in the chair as much as they play.
360° armrests with a fold-away option
Full rotation on the main shaft plus 40° of inward and outward tilt covers keyboard, controller and desk-free postures, and folding armrests let the chair tuck under a desk. These are the small things that decide whether a chair works in a real room.
Three things I would change
1. The published fit ranges exclude a lot of people
AutoFull states the lumbar system is ideal for users between 5'9" and 6'2" and the headrest for 5'3" to 6'4". Those are narrow windows. If you are under 5'9", the chair’s best feature — the tracking lumbar support — is being sold to you outside its stated range, and no amount of knob adjustment fixes a backrest geometry designed around a taller torso. This is the specification I would check hardest before ordering.
2. Massage in a chair is a comfort feature, not a therapeutic one
Shiatsu massage in a lumbar unit feels pleasant and can help you notice when you have been seated too long. It does not treat back pain, and it is not a substitute for standing up. The €300 premium over the vibration-massage M6 Ultra 2.0 buys exactly this one feature, and I would think hard about whether it is worth a third of the chair’s price to you.
3. Powered features add failure points and a cable
Fans, heating elements and a massage motor all need power and all can fail, and none of them are things a chair traditionally has to worry about across a five-year life. The listing I read does not state a warranty term for the electronic components specifically. A chair is a long-lived purchase; ask what happens in year three when a fan stops before you commit at this price.
Who should buy it — and who should skip it
Buy it if
- You are between roughly 5'9" and 6'2" — the range AutoFull designed the lumbar system around — and you sit for long, uninterrupted sessions.
- Heat build-up is your actual complaint with your current chair, because active cooling is rare and this addresses it directly.
- You want gaming-chair aesthetics without giving up genuine four-way lumbar adjustment.
Skip it if
- You are shorter than the stated lumbar range — the chair’s main advantage does not apply to you.
- You are buying it to treat existing back pain; that is a conversation for a clinician and a properly fitted task chair.
- The massage function is not important to you, in which case the M6 Ultra 2.0 at €599.99 is the same chair for €300 less.
The verdict
The M6 Ultra+ 2.0 is a more serious piece of ergonomic design than the category usually produces. Four-way tracking lumbar support, a genuinely adjustable headrest and active seat climate control are features I would like to see on office chairs costing more than this. My reservations are about fit and value rather than quality: AutoFull’s own published height ranges are narrow, and the shiatsu upgrade costs €300 for a comfort feature. Check your height against the stated ranges first. If you fall inside them and heat is your problem, this is a strong buy at €899.99; if the massage is the only thing pulling you to the plus model, take the €599.99 variant and spend the difference on a decent desk.
Check the M6 Ultra+ 2.0 and the lower-priced M6 Ultra 2.0 at AutoFull — compare the shiatsu and vibration variants carefully, because the €300 gap buys one specific feature.
