I sat on the butt-cooling AutoFull M6 Ultra gaming chair in the middle of a heatwave – but did it actually keep my buns chilly?

AutoFull M6 Ultra: Two-minute review

Alright, I'm going to be totally honest: I wasn't expecting the AutoFull M6 Ultra gaming chair to be very good. I've seen gaming chairs with fancy massage and cooling functions before, and I was never very impressed with them (in fact, I had a good laugh about one of them during Amazon Prime Day 2022).

On paper, it sounds a bit ridiculous: a premium gaming chair absolutely loaded with features, from '6D' armrests to built-in fans and even a heating element that helps keep your posterior the perfect temperature. In practice, though, it delivers on all the advertised promises - almost all of them, anyway.

For starters, it's genuinely very comfortable and feels like a premium product. The cushioning is nice and plush on the seat, back, and headrest, and the PU leather finish is pleasantly cool to the touch. Both the base of the seat and the lumbar support section are perforated to make them more breathable, too.

I'd potentially go so far as to call this one of the best gaming chairs out there right now - but more due to the overall high quality and comfort, rather than the extra fancy features. That being said, the cooling and heating functions genuinely do work - more on that later in this review.

In fact, I'd have to admit that some of my issues with the AutoFull M6 Ultra are more to do with me than the chair itself. I'm 6'3", and I can't help but feel like this chair simply wasn't designed for someone of my stature. But if you're six feet tall or less, this could be the perfect chair for you - especially if you live somewhere with a warm climate.

AutoFull M6 Ultra: Price and availability

With a $799.99 / £799.99 (around AU$1,225) price tag, the M6 Ultra is far from affordable. Even relatively premium offerings from respected gaming chair brands like SecretLab and NobleChairs are cheaper.

That being said, it's worth noting that this is the highest-end model sold by AutoFull. If you're willing to sacrifice the massage and cooling/heating functions, there's also the M6 Elite, which retails for $599.99 / £599.99 (around AU$920) and retains the same high build quality without the extra bells and whistles.

Plus, at the time of writing, the M6 Ultra is on sale at AutoFull's website (seemingly in every territory), bringing the price down to a far more reasonable $569.99 / £569.99 (around AU$875). In that range, it's going up against chairs like Razer's Iskur V2 and the SecretLab Titan Evo, and for my money, it performs reasonably well against those rivals.

AutoFull M6 Ultra: Design and features

To describe this gaming chair as feature-rich is almost an understatement; I'm frankly surprised it doesn't also cook my dinner and do my taxes. In terms of its core construction, it's nothing groundbreaking; we've got a five-armed ergonomic base with smooth rolling casters, a fully reclining backrest, and a racing seat design with sturdy but not uncomfortable bolsters on either side.

The armrests feature '6D' movement, which sadly doesn't mean that they're capable of accessing a forbidden sixth dimension of spacetime, but rather that they can move in six specific directions.

This makes the armrest position highly customizable, which is great, though I would've liked to see a little more resistance on the 360-degree rotation; it's a bit too easy to push them out of position when getting up or sitting down, but this is an admittedly very minor quibble on my part.

The recline function works well, with a sturdy feel to the backrest and the option to go back almost to a fully horizontal position. Combined with the extendable flip-up legrest, it's certainly one of the most comfortable gaming chairs - you could reasonably take a comfortable nap in the M6 Ultra if you were so inclined, or reclined (sorry).

The headrest is very plush, but - somewhat unusually for a premium gaming chair - isn't removable. Instead, it's mounted on an adjustable bracket, and the sides can be 'folded' inwards too for a cradling effect. It's good enough, but I can't help but feel like a magnetic headrest would've been a better choice here. The lumbar support is also fully adjustable (and very comfy), but can't be removed without damaging the chair.

Now, onto the good stuff: does this chair really keep your bum cool? Surprisingly, yes, it does. Two fans in the breathable seat center can be set to three different power levels, and they definitely do keep the temperature down. I reviewed the M6 Ultra at the peak of a nasty heatwave here in the UK, and while I wasn't exactly blown away (no pun intended) by the cooling, it did make a noticeable difference after an extended period in the chair.

The heating function works quite well, too. Given the current temperatures at the time of writing, I was reluctant to use it for very long, but it certainly does get nice and toasty. It's easy to imagine how pleasant that could be in the middle of winter.

The same can't really be said for the 'massage' functionality, unfortunately. This is basically just a vibration motor concealed in the lumbar cushion, which can be set to pulse at three different speeds. I was hoping for a more active massage experience (like those bulky chairs you see at malls and airports) and ultimately found it more annoying than relaxing.

All of these features are controlled by three buttons on the seat.

AutoFull M6 Ultra: Performance

So, how does the AutoFull M6 Ultra actually perform in practice? Well, for me, not great. At 6'3", I'm simply a bit too tall for this gaming chair; the headrest was the main offender, as setting it to the maximum height was still a little too low for me to sit comfortably. The NobleChairs Hero TX that I use as my regular desk chair stands about two inches taller by comparison.

Luckily, I have a 5'9" fiancé who I was able to persuade (read: bribe with snacks) into using the chair for a few days, and he reported that it was actually fantastically comfortable if you're not excessively tall. Even after a five-hour Stardew Valley binge, it was comfy and sweat-free thanks to the cooling function. Consider this a warning, then: if you're my height or taller, this might not be the chair for you.

In terms of other body types, the M6 Ultra is wide enough to accommodate most plus-sized users, and it works well for cross-legged sitting as well. The lumbar support is genuinely great (something I'm always on the lookout for in desk chairs), and it's very easy to find a natural elbow position thanks to the multi-directional armrests. It's also Lucy-approved, an extremely important certification for any chair, as you can see in the picture below.

When it comes to the question of longevity, it's always difficult to gauge exactly how well a chair will last based on a few weeks reviewing it, but I have to say that I feel confident about the staying power of the M6 Ultra. The stitching looks and feels high-quality, and the chair as a whole is very robust, with mostly metal and leather in its construction; the only plastic I could see here was the external covers for the seat hinges and the lumbar adjustment dial.

One last thing I have to bring up: don't expect to be rolling around in this thing unless you've also got a USB power bank to connect to it. The USB cable that powers the extra features is simply too short to practically connect it to a PC or wall outlet unless you remain perfectly still, so the best solution is to plug it into a portable charger and store that in the handy pocket on the back of the chair.

Secretlab Titan Evo 2022 XL
The Titan Evo range from Secretlab is one of the best in the business and its 2022 range is excellent. It offers a similar package to the Kaiser 3 XL but will give you a better finish and build quality that many folks value and don't mind paying extra for.

Here's our full Secretlab Titan Evo 2022 review

Razer Iskur XL
The XL variant of the Razer Iskur will cater for the bigger player just as much as the Kaiser 3 XL but it will offer perhaps a more 'fulsome' lumbar system - an entire panel of the chair's back can be moved into the perfect position.

How we tested the AutoFull M6 Ultra

I spent more than a week testing out the AutoFull M6 Ultra gaming chair, swapping out my usual desk chair, the NobleChairs Hero TX, to use it daily at home, both for work (since I work from home) and a fair bit of gaming.

I'm 6'3" and weigh about 95kg (209lbs), so I'm on the large side - which is why I had both my 5'9" partner and 5'11" friend spend some time in the chair too, to get a properly rounded idea of how comfortable it is for different people.

We all tested out various positions for the headrest, armrests, and lumbar cushion, as well as seeing how comfortable the footrest and additional features were. I carefully documented their feedback and also took the time to read some product reviews on AutoFull's own website, to make sure there were no glaring issues with the M6 Ultra that I'd somehow missed in my own testing (and there weren't, so my pride remains intact).
