The AutoFull M6 Ultra is a Premium Gaming Chair Punching Above Its Weight

The AutoFull M6 Ultra gaming chair distinguishes itself from other premium offerings by providing built-in heating, cooling, and massage functionality. Fortunately, despite these unique additions, AutoFull didn't forget to make the chair itself high quality with the same type of comfort features found in some of the best gaming chairs that sometimes significantly more. It still has some room for improvement in certain areas, but the M6 Ultra nevertheless makes a compelling argument for becoming your go-to desk chair.

AutoFull M6 Ultra Gaming Chair – Options and Assembly

Available in black with gold accents, or white with blue accents, the M6 Ultra is the top-of-the line offering in AutoFull's M6 series, providing nearly every available option you’d see in a high-end chair. The M6 Ultra features an elastic lumbar massage, 3D ergonomic neck pillow, ventilated (cooling) and heated seating, dynamic tracking lumbar support, 6D adjustable armrests, and a retractable footrest.

Aside from the aesthetic differences, the rest of the M6 series, labeled Pro, Elite, and Basic, successively lose features as you go down the tiers – the M6 Pro lacks the M6 Ultra's massage option and headrest, the M6 Elite drops the cooling and heating, and the M6 Basic lacks the 6D armrests and retractable footrest. But the M6 Ultra is the full package that earns its higher asking price.

At roughly three feet long, just over two feet wide, and about 17.5-inches high, the M6 Ultra ships in a more compact box than similar chairs, but at nearly 80 pounds, is still a two person job to move. Per usual, the box arrived in bad shape from shipping, but the contents survived without damage.

Upon opening the box, you're greeted with a visual assembly poster, as well as a separate glossy sheet with a QR code leading to an assembly video on YouTube. As is typical, I found neither the assembly poster nor video sufficient on their own to put the chair together. For instance, although the video was clearer to me than the poster, it was also slightly out-of-date, with, for example, the arms not being shown pre-assembled like they are now out-of-the-box.

Overall assembly was relatively easy, however, requiring just the two included Allen key wrenches for tightening various screws and bolts. The only hard part for me, and a step that needed a second person, was sliding and aligning the backrest into the slots and screwing it in.

Further easing the assembly process is that the headset and lumbar support are already pre-installed on the seat’s back. Neither is surprising considering that the headrest is on a telescoping rail for adjustment and the lumbar both auto adjusts and has dual massage motors built-in.

AutoFull M6 Ultra Gaming Chair – Comfort and Performance

Once assembled, the overall feel of the M6 Ultra is solid. The cushioning inside the PU leather material is on the firmer side, but with just enough give, making me believe it would hold up well long-term even if a user was near the chair's maximum 396-pound weight limit.

Unlike a lot of chairs in this category, the headrest neck pillow is permanently attached. Fortunately, it moves both up and down, as well as forwards and backwards, for good adjustability. The sides of the neck pillow can also be bent inwards, which I like for the cradling effect it provides. While the neck pillow is also on the firm side, it's filled with gel, so it has more give. It's easy to adjust, and, more importantly, stays in place once set.

Marketing buzzwords for armrests have descended into meaninglessness of late, with everything from 360-degree to 4D used for how adjustable they are. AutoFull is no different, using the term "6D" for the armrests on the M6 Ultra. While they don't split like they would at the end of the "5D" armrests on the Cougar Armor Evo M, for example, the M6 Ultra's armrests do just about anything else you can think of.

The armrests can be raised up and down, tilted down, tilted up, tilted to the side, rotated 360-degrees, and more. In short, you can place these in just about any position that's needed, including out of the way. Even better, the arms generally stay in place once set, a seemingly simple concept other chairs have struggled with realizing.

The footrest slides out and unfolds when you want to use it. It's not the sturdiest footrest out there, but works well enough when reclining the chair to its maximum 160-degrees. Combined with the adjustability of the armrests, there are some good reclined use cases with the M6 Ultra, including reading a book or portable gaming with something like a Steam Deck or Nintendo Switch.

The firm seat is comfortable enough, although I would have preferred the better ergonomics of the more cradled design found on chairs like the Armor Evo M. It's likely that AutoFull chose this type of seat design in part to accommodate the ventilation and heating system, as well as the three control buttons accessible on the right top of the seat itself. Surprisingly, even after sitting for hours at a time over several months of usage, I never once noticed or felt any of the embedded electronics. If you like a supportive seat without a lot of give, then you'll no doubt like sitting on this for even your longest gaming or working sessions.

The AutoFull M6 Ultra is one of my favorite gaming chairs to date.

There's a single USB-A cable that extends about four feet from the back of the chair. This is used to power the graphene heating system and dual fans in the seat, as well as the dual massage motors in the lumbar support. As opposed to an insert, like on the Mavix M9, the M6 Ultra's massage and climate system is seamlessly integrated, which is why it's unfortunate that no battery pack is included. You either need to be tethered to a USB port, or, like me, supply your own USB battery pack, which I placed in the sleeve on the back of the chair. Fortunately, the M6 Ultra's massage and climate system is quite efficient, using only roughly 1 - 2% of my USB battery pack's capacity per session, even with everything set to maximum.

Heat can be set to three levels and tops out at a toasty 122° F, which is comforting, but can be intense. Cooling similarly has three fan levels, with the lowest setting barely audible. The coolest setting, although the noisiest in that it clearly sounds like a fan is running, does a surprisingly good job at chilling my bottom and keeping me cool overall during even the most intense gaming sessions.

The lumbar massage, surprise, also has three intensity levels to choose from. Although it's called massage, there's no movement up and down or left and right in the lumbar support, just two points of vibration at roughly the apex of the outward curve. It's not the most nuanced type of massage, but it does feel good for what it is.

Besides massage, the lumbar has another neat feature where you can adjust how much it goes forward or backward in reaction to your own movements, including locking it in place. I have mine set to just a little give when I move as I like the feeling of support in my lower back.

According to AutoFull, as long as you fall between 5 feet 9 inches and 6 feet 2 inches in height, the dynamic lumbar tracking should properly auto-adjust to your spine. At just over 5 feet 9 inches, I can confirm that it does exactly that for me.
