Let me start with the assembly
my back suffered to put it together, it seems like it's not well designed for screws, etc.
the color is very beautiful, the leatherette is very soft, but I don't see it lasting many years
it is comfortable, yes, but I can see in the seams and folds that the workmanship is very sloppy in general!
I was between the Corsair and this Kaiser II.
The truth is, okay, I was giving 360 but with 100 more I could get the Corsair, which I have seen, sat on, etc., and it is nothing like the Kaiser, it's much more premium!
For those of you considering it, I say look elsewhere! Preferably Corsair
If someone asked me, I wouldn't recommend it as a first choice! What a pity....
3 stars for how comfortable it is

What I was missing all these years. Huge, high-quality, beautiful, extremely comfortable with reclining function and manual backrest and automatic seat where you can make it sturdy or have it fall back instantly, and a lever to activate and deactivate it (I'm talking about the seat recline).

My cousin, the FAT GUY, bought it about a month ago!! (Don’t judge me, that’s what I call him and that’s what he calls me... I’m 86kg, he’s 87kg, both gym-goers)
Very comfortable and relaxing... You can easily fall asleep on it, especially if you recline and chill...
Now we just have to see how durable it will be over time, although it seems sturdy and of very good quality.

truly the best in chairs. and their representative in Greece is incredible in everything, they truly deserve it...

I have the AD12XL V2 model for the last 4 years. After almost daily use all these years, I can say that as a construction, the chair is quite good and sturdy. Among the very serious negatives, as shown in the photo, is that the leatherette of the seat frays, dries out, and polymerizes (cracks). Also, the threads in the seams slowly break. A less important disadvantage is that the straps on the cushions loosen and you can't tighten the slack they create (you can't tighten it). So after 4 years of use, I am in the process of replacing the seat with that of the Kaiser 2 model, which seems compatible. I would therefore suggest that if you want to extend the life of the leatherette, you use a mild leatherette cleaner/conditioner from time to time.

Excellent chair in terms of support and comfort. Very sturdy. I have had it for about 4 years.
I am 1.75m and my son is 1.88m. For him, the height is fine. I am also quite comfortable but my feet do not touch the ground.
The only drawback, and the reason I am removing one star, is that the leatherette tears over time even though we sit wearing cotton shorts or cotton sweatpants. This is unacceptable for a chair bought for 349 euros.

So if you sit every day for two years in pajamas, not in jeans or hard pants, then the fabric will wear out. In fact, I would suggest improving the durability of the leather quality. It's a real shame! I don't have cats or dogs either!

I've had it for 7 years, I wouldn't buy it again

(+)
Steel construction quality
You can easily recline it and sleep normally
The memory foam on the seat is comfortable
After all this time, none of the wheels have any issues nor does the backrest tilt

(-)
The back cushion is so hard it's like it's not even there, I put it aside within the first few months
In the areas you touch often, the color has faded
If you work from home and sit for many hours, it doesn't give you an ergonomic/proper body posture
On hot days, because of the leather, you sweat very easily on it
If you don't wear cotton clothing, you keep sliding on the leather and have to readjust your position
The elastics, even though I never moved the cushion, have stretched out and sagged!

Conclusion
Considering the price and the negatives, I wouldn't buy it again!

I have had it for about 3+ years. Truly the best. Nothing has happened to it, it is very high build quality. I am 112 kg and 182 cm tall. I sit for hours, extremely comfortable...! I recommend it.

The best, very sturdy construction, comfortable and being 'XL' it has a lot of comfort and space. Personally, I removed the cushion because it wasn't convenient for me, otherwise 5/5 ⭐

Good evening! Let me write something too after a long time, so, without exaggeration, it is like new after almost 2.5 years except for the foam which has started to lose its density, but okay, that's a detail. It was worth it and more! BEST GAMING CHAIR!

edit: 4/4/2026
after almost 4 years it really was worth every euro, the leather has started to show wear and over time it will start to tear, the foam sinks faster and takes longer to recover, which is essentially normal wear no matter how high quality a product is. Personally, I have to sit at least 3-5 hours to feel any discomfort. It was definitely worth it at the 300 I bought it for, now at these prices 400-500€ I don't know if it's worth it.

I bought it because I saw a top government minister using it. Suitable for autumn and spring. In summer, it's excessively hot. In winter, it's quite cold. However, it provides good support and is sturdy. You can sit comfortably on it for many hours. I think it also comes in fabric and now in mesh, so I recommend it without reservation.

120 kilos, about 4 years, it doesn't feel anything

I've had it for almost a year now, it's the most comfortable chair I've ever had. The construction seems very good, the material breathes a little but for summer it's quite warm. I hope it lasts over time.

There is no better in its category. A heavy and sturdy chair that I have had for over 2 years, it has not made the slightest noise of wear and the fabric material has not been altered. It can comfortably accommodate anyone who needs a chair for many hours and with a lot of weight. The cost is easily recouped.

One of the worst purchases
I bought the chair because of unboxholics as they praised it,
from the very first moment it started making a crack when I sat down (I never found out where it's from),
the leather has frayed
and now two years later when I sit back the backrest goes very far back
stay away if you are going to spend so much money and in the first year it frays without excessive use and in two or three years you are looking for another
unacceptable

Very warm even in winter if you play for many hours. Apart from that, it is the best choice for a chair

In 1.5 years of daily use at work in a 24-hour position, the seat came apart, and in communication with the company, they told me that the warranty only covers metal parts, and this for replacement goes to upholstery, or the change of the entire seat at a cost of €90

I have been using it for about a year.

As soon as I set it up and sat on it, I realized that this is an extremely high-quality product, which is going to offer me great comfort in my work.

Edit 03/12/2024: Like new, and I use it (almost) on a daily basis for at least 8 hours a day (because of my job)

Edit 30/10/2025: It is still in perfect condition, and I use it (still) on a daily basis, as I mentioned before.

There are no words to describe how comfortable it is. I work all day on the computer, so I always had good chairs, but this one is by far the best I have tried. Minimalistic without lights and bells, you pay for build quality and nothing else.

No more than 3 years together. For the past year, the shock absorber has been broken, I replaced it and now the tilt mechanism is also broken. Okay, I weigh 150 kilograms, but I am within the chair's limits. I don't use it for more than 4-5 hours a day.
On the positive side, it is very nice and stable, not too warm, with very comfortable cushions, but...

I bought it on the 19th, the faux leather has worn out, I would have expected better quality for this price. (The IKEA chair lasted 15 years). Very comfortable and if you overlook that, it is the best construction I have seen, but yes, better go for Secret Labs

Probably the best chair you will find on the market! Terrific quality and comfortable. I weigh 90 kilograms and I have had it for two years+ with daily and extended use, and it hasn't suffered any damage, nor has it developed any dents or deformations in the seat. Finally, I would like to add that it is quite to very large in terms of space and it is very expensive, especially when we are talking about a chair, but it is the best in its category!

Edit: For those of you who didn't find the review helpful, go ahead and buy a kitchen chair for 10 euros and try to eat something comfortably at your desk.

I have had this chair in my possession for 2 years and something. With several hours of use throughout the day, it feels like new. It can withstand weight and pressure no matter how you sit, unlike the no-name chairs in the market, and it is extremely sturdy. I have no words for its quality and comfort. I highly recommend it, especially for someone who spends hours on the computer. 5 stars are not enough

It broke from the mechanism side, from below... I had simple office chairs for 15 years and they didn't break. Go for Secret Lab... for an extra 150€ they are immortal. Also, there is no service available.
