Quersus ICOS.2: One-minute review
The Quersus ICOS.2 is a striking gaming chair with a few unique features that help it stand out even more in the homogeneous gaming chair space.
The slender frame and sharp angles certainly look different, but despite this, the ICOS.2 remains quite formal. True to the brand’s claim, it wouldn’t look out of place in an office.
Overall build quality is quite good. The velvet upholstery on my review unit was incredibly soft, eclipsing even the best gaming chair fabrics in terms of feel. The wheel base is a highlight, although some of the plastics in other areas are less impressive, and the arm rests are prone to wobbling.
There are a few unconventional features on the ICOS.2. For a start, there’s no head pillow, but rather an integrated, adjustable headrest. I personally found this very comfortable, but its lack of give and inability to lower it to neck-level might deter some users.
Another unique aspect of the ICOS.2 is the ability to slide the seat base back and forth – an adjustment usually absent from gaming chairs. Naturally, you can also adjust seat height, and the minimum setting is pleasingly low to the ground – but the maximum will likely prove disappointingly short for tall users.
There’s also no traditional recline function on the ICOS.2. What you get instead is a tilt function that allows the backrest to lean back to a large degree, with a generous amount of resistance adjustments. There’s also a dial to lock and unlock the tilt angle in position. In my view, this tilt function does a fine job of making up for the omission of a recline system.
Integrated lumbar support is featured in the ICOS.2, too, which can be adjusted for height and depth. The range for the latter is good, and the dial is very easy to use, even while seated. The height range is more limited, and you seem to sacrifice lumbar depth the lower down it goes, which isn’t ideal.
Overall comfort is good, with plenty of padding and space on both the seat and the backrest to remain comfortable for long periods.
Assembling the ICOS.2 was a straightforward process. It came in two boxes, both neatly packaged, and included a large handle with two magnetically attachable hex keys. I could attach the seat to the backrest while both laid on the floor, which made the process easier.
At over £600 (it's unfortunately only available in the UK and EU right now), the ICOS.2 is mighty expensive, eclipsing even the biggest names in the business. And despite its standout features, I don’t think it’s better value than the Secretlab Titan Evo 2022, for instance, which is still the leading light in the gaming chair world.
Quersus ICOS.2 review: Price and availability
- £649 (around $870 / AU$1340)
- Available in UK and EU only
- Expensive end of the market
The ICOS.2 costs £649 (around $870 / AU$1340) and is available now in the UK and EU, in one size only. Various colorways can be had if you opt for the fabric upholstery, but the faux leather finish is currently only available in black. You can also personalize the headrest for an additional £25. The chair comes with a five-year warranty, which is very competitive.
However, the ICOS.2 is on the more expensive end of the gaming chair spectrum, and considering the competition in this space, it's a big ask. It costs more than the Secretlab Titan Evo 2022, which we think is the best gaming chair around, and I don’t think the ICOS.2 beats it on every front.
If you’re looking for a budget option, the Corsair TC100 Relaxed is one of the best in this regard. It’s comfortable and well-designed, although some parts don’t exactly feel premium – but that’s to be expected at this price.

Quersus ICOS.2 review: Design and aesthetics
- Unique look and features
- Cheap in places
- Flimsy arms
The ICOS.2 sets itself apart from other gaming chairs with its streamlined figure. The seat and backrest are much thinner than you might expect, and the various sharp angles wouldn’t look out of place on a stealth jet.
At the same time, though, the ICOS.2 is also quite understated, especially in the monochromatic finishes. Quersus pitches this chair as being suitable for both gaming and working environments, and I think it’s struck this balance well in terms of design.
The velvet finish I had in my review unit felt super soft. It’s also water-repellent and seems fitted to a high standard. However, certain aspects of the ICOS.2 feel a little cheap by comparison. Many of the plastics don’t look or feel as expensive, and the sharp rim of the backrest frame where it meets the upholstery is an oversight.
Some of the adjustment levers are a little flimsy, although thankfully, this doesn’t affect their operation. The lateral wobble of armrests is a little more concerning, although this shouldn’t present a problem under normal usage. They feel more plush and forgiving than many other armrests, which is good since you’ll be in constant contact with them.
The wheel base also seems built to a high standard, with its metal construction feeling sturdy yet light, at least compared to others. I appreciated the rounded ends of the spokes, too, as these make it somewhat less painful if you stub your heels into them.
The casters complement the base well: their gloss finish and hollowed-out centers are nice touches, and they’re also conducive to smooth glides – although there’s more grip than you might expect on carpeted surfaces, which helps to keep the chair stable.
Quersus ICOS.2 review: Comfort and Adjustability
- Seat base depth adjustments
- No recline, only tilt
- Shallow height adjustments
Despite the perceived lack of padding, the seat of the ICOS.2 provided me with enough cushioning to remain comfortable in it for extended periods. It’s also wide and there are no side bolsters, which means it should accommodate a variety of body shapes and seating styles with ease.
The backrest is just as soft and comfortable, and the bolsters here open out wide, so I didn’t feel hemmed in, and there was no danger of knocking them with elbows – a pet peeve of mine with gaming chairs.
One of the unique features of the ICOS.2 is its headrest. Rather than including a separate pillow, head support is integrated within the backrest and can be adjusted for height by sliding it up and down. There’s no lever or button to hold down while doing this, though, which means it requires a fair amount of force to make these adjustments.
Although it doesn’t protrude all that much compared to more traditional gaming chair head pillows, I still found it comfortable and supportive; in fact, I was thankful for the minimal protrusion, as I often find pillows too thick.
One of the drawbacks of this system, though, is the lack of versatility. With head pillows, you can place them lower down if you wish to give your neck more support. You can also remove them altogether if you find them uncomfortable. Neither of these options is available to you here.
What you think might be the recline lever on the left side is actually used to slide the seat forwards and backwards. This is rather unique in the world of gaming chairs, and a welcome addition for those who prize good seating ergonomics.
If you want to recline in the ICOS.2, then you’ll have to use its tilt function instead, unlocked via a dial on the left. The seat only tilts back slightly, whereas the backrest tilts all the way to 140 degrees.
You can then lock the backrest into your desired position with said left dial. In effect, then, this tilt function replaces the more traditional recline function of other gaming chairs, and it does a good job of doing so – although some rocking still remains after you’ve locked the tilt mechanism in your desired position, so it’s not the most robust of mechanisms.
On the right, you’ll find the dial for adjusting the resistance of the tilt. I found this stiff to turn and awkward to reach, owing to the lack of outward protrusion. However, it does at least provide a generous range of resistance levels.
The ICOS.2 also features integrated lumbar support, which can be adjusted for both height and protrusion, which I’m always thankful to see, since some systems only allow for depth alterations.
A single dial is used for both adjustments, which is located on the back right-hand side of the backrest. I found it easy enough to reach and use while seated, although I can imagine some may struggle.
The dial has an ergonomic shape that helps with twists, and the subtle rubberized finish makes it easy to grip. It turns much easier than the tilt resistance dial and other lumbar dials I’ve experienced. It feels more like loosening or tightening a screw, becoming less resistant the further inward the lumbar retracts.
The range of depth adjustments it offers is good, too. And unlike other integrated lumbar systems I’ve experienced, the one on the ICOS.2 doesn’t feel as sharp; it seems to offer more cushioning than is typical.
To adjust the height of the lumbar, you pull out the dial first before turning. As with the depth adjustments, these turns feel easy to make, although the range of positions is limited. Also, when the lumbar is at its lowest position, it feels as if the depth retracts somewhat, leading to a feeling of less support.
The seat of the ICOS.2 can go lower to the ground than many other gaming chairs I’ve tried, but it might not rise enough to meet the needs of taller folk. This is disappointing considering Quersus’ claim that the ICOS.2 has a universal fit, and suggests that a larger version won’t be coming.
The arms on the ICOS.2 can be adjusted across four dimensions. Their height range should be sufficient for most to get comfortable, but the width range is quite limited; personally, I would’ve liked them to be able to move inwards more.
There are no levers or buttons you have to hold when moving the arms inwards or outwards, back and forth, or when rotating their angle. This means adjusting them requires a fair amount of force, which causes rather loud clicks as various mechanisms ratchet through their notches. As a result, it feels quite clunky to make these adjustments.
One positive aspect of the arm rests, aside from their aforementioned padding, is that they can easily be removed and replaced with other designs, varying in their shape and material, which Quersus says it’s currently in the process of creating.
Quersus ICOS.2 review: Assembly
Assembling the ICOS.2 proved to be relatively easy. The unit came in two separate boxes that were very neatly packaged, and included is a large handle and two magnetically attached hex wrenches
I managed to build it solo without trouble. You can attach the seat base to the backrest while both are resting on the floor, which alleviates one of the most laborious aspects of putting together a gaming chair.
One of the hardest parts of the build was attaching the casters to the seat base, as I found the fit quite tight. But this is a minor grievance, all things considered. The chair isn’t too heavy, either, at least when compared to other gaming chairs.
Should I buy the Quersus ICOS.2?
Buy it if...
You want an integrated headrest
I really liked the adjustable headrest, offering enough support and adjustability to get comfortable.
You want to adjust seat depth
Not many gaming chairs allow you to alter the seat depth, which ergonomists will tell you is an important aspect to consider.
Don't buy it if...
You want to save money
There’s no doubt that the ICOS.2 is expensive, even by gaming chair standards, and there are better value alternatives if you don’t need the niche features
You want a traditional recline
While the tilt function admirably makes up for the lack of a traditional recline, some might not like it.

How I tested the Quersus ICOS.2
- Tested for two days
- Tried all available adjustments
- Extensive gaming chair experience
I tested the ICOS.2 for a few days. I made sure to make all of its available adjustments, and tried various seating positions and styles to comprehensively assess its performance across different scenarios.
I have been gaming for decades, and during that time, I’ve used a number of gaming and office chairs, ranging from budget affairs to premium offerings. I have also reviewed a number of gaming chairs, too, ranging in their designs and price points.
