Do you remember the 'GC PRO' gaming chair that chair brand 'SIDIZ' first introduced in 2023 for esports players and gamers? It created a huge buzz among gamers with its firm backrest, Korea's first seat cooling system, and surprisingly delicate tilting and armrest adjustment features.

And in September 2026, 'GC PRO Renewal', the official gaming chair tasked with supporting the performance of the Korean national esports team for the 2026 Aichi-Nagoya Asian Games, was officially unveiled. As SIDIZ GC PRO was the product that supported the national team's top performance during the 2022 Hangzhou Asian Games, SIDIZ has once again introduced an upgraded gaming chair for the esports athletes competing in these Nagoya Asian Games.

Having personally used the previous GC PRO in the past, I experienced firsthand the new possibilities of a gaming chair. That made the news of this renewal all the more welcome. So, what noticeable evolutions have occurred over these three years? Let's take a detailed look at the key features of the GC PRO Renewal designed to captivate pro players and gamers who compete for every 1% win rate.

One of the most bothering elements for gamers during long, intense ranked matches or large-scale boss raids is the accumulation of body heat in the lower body. Chairs with PU leather or leather exteriors certainly look great and offer a premium aesthetic, but they carry a critical weakness: they aren't very comfortable when it comes to dissipating user heat.

The GC PRO Renewal cleanly resolves this issue by incorporating a '3-step intensity-adjustable Cooling Seat' inspired by automotive car seat mechanisms. Fans inside the seat cushion circulate air across the contact surface, blowing away the stuffiness around the hips and thighs. While the previous model provided a level of cooling where you'd notice "Oh, there's a subtle breeze" or feel sweaty when switching to another chair, the cooling seat on the GC PRO Renewal offers noticeably upgraded cooling performance—enough to make you exclaim "Now that's definitely cool!" the moment you sit down.

You might wonder, "If the breeze is cool, wouldn't it be noisy?" According to official SIDIZ specifications, even at the strongest Level 3, the measured noise level at headrest height (near the user's ears) is only around 50 dB. This is very quiet—equivalent to everyday background noise in a typical home—and in actual practice, the perceived noise felt even quieter than the figures and descriptions stated in the official specs.

Additionally, while the previous GC PRO relied on power banks for connection, the new GC PRO Renewal overcomes past limitations in various ways through a magnetic cable. Furthermore, the cool-down mode from the original GC PRO has been removed, allowing for uninterrupted use. When using the magnetic cable, 24-hour continuous power supply becomes possible with easy attachment and detachment. Connecting via a power bank retains the advantage of convenient mobility. It was also great that the connection cables adopt USB Type-C terminals, making power connection faster and more convenient.

Every gamer has different physical dimensions. The vertical and horizontal angles when holding a mouse also differ, and even comfortable elbow positioning varies greatly. Sitting postures change even more depending on how games are played—whether sitting at a computer with wrists on the desk to use a keyboard and mouse, holding a gamepad for console gaming, or holding a mobile device or UMPC in hand. Gamers' seating habits across the world are bound to be unique, and the SIDIZ GC PRO Renewal addresses this with its precise '9-Step Armrest'.

The armrests on the GC PRO Renewal integrate 9-step height adjustment, 7-step angle and rotation, and front-and-back depth adjustment. Furthermore, the tactile feel of the material against the skin is excellent, delivering a seating feel that supports the arms with a balance of non-slip grip, moderate plushness, and resilience.

In a PC environment where keyboard and mouse controls dominate, adjusting the armrest level with the desk or setting it slightly lower for free mouse movement proved useful. Conversely, during console gaming with a gamepad, angling the armrests inward provided proper elbow support, significantly reducing the load on the shoulders and arms. Personally, in UMPC or mobile gaming setups where the upper body tends to lean back slightly, I prefer supporting my forearms rather than my elbows on the armrests, and the chair stably supported this posture as well, resulting in much less fatigue during extended play sessions.

The finishing touch for any gaming room is naturally LED lighting. Located on the back of the GC PRO Renewal's backrest, the 'LED Ambient Light' goes beyond being a simple chair to create a perfect gaming vibe. Of course, the seated user can't see it... but first of all, it looks extremely nice.

What sets it apart from the previous GC PRO is that the LED operation button is built into the cooling seat controller, placed for easy access by the user. The original GC PRO turned on by touching under the SIDIZ logo on the backrest. That seemed designed to be pressed when wrapping up a session and organizing your desk, but controlling the LEDs directly from your seat on the GC PRO Renewal proved far more convenient.

Supporting a total of 4 lighting modes, it allows customization to match your desktop RGB setup or personal preference. The subtle glow adds an immersive feel, making streaming setups or dark rooms feel like a private, dedicated gaming sanctuary.

If you currently use a chair with a tilt function, you'll relate immediately: most chairs have a slight play or give pushing back even when tilting is locked. However, the GC PRO Renewal's 'Gaming Tilt' minimizes play to an extreme degree, supporting a perfect 90-degree right-angle setup.

It can be locked at up to 4 backrest angle steps, and tilt tension is also finely adjustable across 4 levels. During intense firefights where every second counts, you can firmly lock the backrest to focus in an upright posture, then unlock it during match queues or loading screens to lean back comfortably and rest.

The performance of the tilt tension adjustment was particularly impressive; increasing the tension firmly supported the body unless pushed with deliberate force, while loosening it to the minimum allowed a smooth recline with just a gentle lean back of the head—a refreshing and convenient experience.

The signature element of the SIDIZ GC PRO—and a feature that might polarize opinions at first glance—is the appearance of the 'Wing-type Headrest'. Its wide surface area might make it look slightly awkward. However, thanks to surprisingly smooth angle and position adjustments and that generous surface area, it actually stands out as a strong positive for users. While most gaming chairs adopt integrated backrests without a separate headrest, this is a major defining feature and advantage of the SIDIZ GC PRO Renewal.

Staring at a monitor for extended periods easily leads to forward head posture. The Wing-type Headrest on the GC PRO Renewal provides broad, stable support for the back of the neck and head, relieving pressure on the neck. Featuring a curved structure spreading out to both sides like wings, it serves as a perfect support where you can lean your head back and relax comfortably during queues or breaks, as well as while deeply focused in-game.

The core of sitting comfort in any chair is the foam. The GC PRO Renewal applies high-density sponge 'Ultra Comfort Foam'. Thanks to this, it evenly distributes body weight when seated while absorbing external movement vibrations, boasting steady support even during vigorous gestures or movements in gameplay.

Additionally, the seat depth can be finely adjusted forward and backward to match the gamer's body type. As a result, users of any height or build can experience a custom-fitted feel tailored specifically to them.

Floor scratches caused by dragging a chair are a hidden headache for home gamers. The GC PRO Renewal adopts unique 'hollow-design wheels' with an open center. Thinking about it, most wheeled chairs have solid wheel centers. Thanks to the open-center look, it delivers both functional strength and stylish aesthetics, killing two birds with one stone.

These unique wheels not only create a futuristic design effect but also use smooth, solid urethane material to minimize floor damage while rolling smoothly. In particular, while sitting still, they hold firmly without wobbling, yet when pushed to reposition, they roll effortlessly without friction—a very satisfying mobility experience.

At 181 cm and 86 kg, speaking as someone on the larger build side, the GC PRO Renewal was remarkably cozy and comfortable. Having experienced the SIDIZ GC PRO Renewal firsthand, I strongly felt that it is not merely a minor cosmetic tweak, but a 'true national team gaming chair' that meticulously resolves even the finest inconveniences gamers encounter in-game.

Furthermore, the 15-year free quality warranty demonstrates SIDIZ's overwhelming confidence in product durability. The mere fact that a 15-year warranty policy—rare even in general office furniture—has been applied to a gaming chair makes it worth buying. Combined with meticulous cooling and tilting options and unique details, it delivers performance that overwhelms competing products in the market.

The GC PRO Renewal is not a gaming chair in name only; it is a product that fully reflects SIDIZ's product philosophy and proprietary ergonomic research. A national team gaming chair created for esports pros who compromise on no detail in their pursuit of victory, and for users who spend most of their day in a chair. Wishing the Korean national esports team good performance and a successful tournament at the upcoming 2026 Aichi-Nagoya Asian Games, I conclude this review of the GC PRO Renewal.
