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

And in September 2026, the official gaming chair responsible for the performance of the national esports team at the 2026 Nagoya Asian Games, 'GC PRO Renewal', was officially unveiled. As the SIDIZ GC PRO was the chair that backed the national team's peak performance at the 2022 Hangzhou Asian Games, SIDIZ has once again presented an upgraded gaming chair for the esports athletes heading into this year's Nagoya Asian Games.

Having personally used the original GC PRO in the past, I experienced firsthand the new possibilities of a gaming chair. That made news of this renewal all the more welcome. I took a deep dive into the key features of the GC PRO Renewal to see what has noticeably evolved over three years and how it captivates the preferences of gamers and pro players competing for every 1% win rate.

One of the biggest nuisances for gamers during long, intense ranked games or massive boss raids is the body heat trapped underneath them. In particular, chairs with PU leather or leather surfaces look great and offer a fantastic aesthetic, but they suffer from a critical flaw: poor heat dissipation, which compromises comfort.

The GC PRO Renewal cleanly solves this issue with a '3-stage intensity-adjustable cooling seat' inspired by car seat mechanisms. Fans inside the seat pan circulate air across the contact area, blowing away stuffiness around the hips and thighs. While the previous model provided a subtle sensation—where you might think "Oh, there's a light breeze" or notice the difference only after switching to another chair ("I'm sweating without it")—the cooling seat on the GC PRO Renewal offers noticeably upgraded cooling performance, making you exclaim "That's genuinely cool!" as soon as you sit down.

You might wonder, "If the airflow is that strong, isn't it noisy?" According to official SIDIZ specifications, even at the strongest Level 3, the measured noise level at the headrest (at ear level) is only around 50 dB. This is very quiet, comparable to typical ambient noise in a home, and the actual perceived noise felt even quieter than the figures and descriptions in the official specs.

Additionally, while the previous GC PRO relied on portable power banks for connection, the GC PRO Renewal overcomes those limitations in multiple ways using a magnetic cable. Furthermore, the Cool Down mode found in the original GC PRO has been removed, allowing uninterrupted use. Using the magnetic cable enables 24-hour continuous power supply with quick and effortless attachment/detachment. Connecting via a power bank still offers the advantage of easy mobility. It was also great that the cables adopt USB Type-C ports, making power connection faster and more convenient.

Every gamer has unique physical proportions. Vertical and horizontal angles when holding a mouse vary from person to person, and even the most comfortable elbow position differs greatly. Sitting postures change further depending on how games are played—whether sitting in front of a computer with wrists on the desk for a keyboard and mouse, holding a gamepad for console gaming, or gripping a mobile device or UMPC. The SIDIZ GC PRO Renewal addresses these varied sitting habits through its precise '9-Step Armrest'.

The armrests of the GC PRO Renewal offer 9 height adjustments, 7 angle and rotation steps, as well as front-to-back depth control. Furthermore, the material feels great against the skin, offering a non-slip, moderately cushioned, and resilient feel that comfortably supports your arms.

In a PC environment where keyboard and mouse controls dominate, aligning the armrests level with desk height—or setting them slightly lower to give the mouse room to move—proved useful. Conversely, when playing console games with a gamepad, angling the armrests inward provided proper elbow support, significantly reducing strain on the shoulders and arms. Personally, when playing on UMPCs or mobile devices where you tend to lean back slightly, I prefer supporting my forearms rather than my elbows on the armrests; even in this posture, it provided stable support, leading to far less fatigue during long gaming sessions.

The ultimate finishing touch for any gaming room is LED lighting. The 'LED Ambient Light' located on the back of the GC PRO Renewal backrest goes beyond being just a chair to create the perfect gaming mood. Of course, the person sitting in it can't see it... but first and foremost, it looks great.

Unlike the previous GC PRO, the LED power button has been moved onto the cooling seat controller, placing it where users can operate it with ease. On the original GC PRO, it turned on by touching under the SIDIZ logo on the backrest. That design seemed intended for toggling when wrapping up a session, but controlling the LEDs directly from your seated position on the GC PRO Renewal proved far more convenient.

It supports 4 lighting modes in total, allowing customization to match your desktop RGB setup or personal taste. The subtly glowing light enhances immersion, creating the feel of a private gaming sanctuary in a streaming setup or a darkened room.

If you use a chair with a tilting mechanism, you can probably relate right away. Most chairs still have a slight play or wobble even when tilting is locked. However, the 'Gaming Tilt' of the GC PRO Renewal minimizes slack to the extreme, supporting a perfect 90-degree upright posture.

You can lock the backrest at up to 4 angles, and tilt tension can also be finely adjusted across 4 levels. During high-stakes encounters where every second counts, you can lock the backrest firmly to maintain focused posture, and during queue or loading screens, unlock it to lean back comfortably—supporting a seamless rhythm between focus and relaxation.

The tilt tension adjustment was particularly impressive. When turned up, it firmly supported the body unless deliberately pushed back with force; conversely, at minimum tension, leaning your head back slightly was enough to recline smoothly, offering a fresh and convenient experience.

A signature aspect of the SIDIZ GC PRO—and one that might divide opinions visually—is the look of its 'Wing Type Headrest'. With its wide surface area, it might look somewhat awkward. However, thanks to smooth angle and height adjustments and that broad surface, it actually turns out to be a major positive for the user. While most gaming chairs opt for an integrated backrest without a separate headrest, this stands out as a distinct key 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 of the GC PRO Renewal supports the back of the neck and head with a wide, stable cradle, reducing strain on the neck. Featuring a curved structure spreading outward like wings, it serves as an ideal support not only when locked into gameplay, but also during queue times or breaks when you want to rest your head back comfortably.

The core of seating comfort is foam. The GC PRO Renewal incorporates high-density 'Ultra Comfort Foam'. This evenly distributes body weight when sitting, absorbs vibrations from external impacts, and provides firm, stable support even during intense movements during gameplay.

Additionally, seat depth can be finely adjusted back and forth to match the gamer's physique. As a result, users of any height or body type can experience a tailored, custom-fit seating feel.

Floor scratches caused by moving chairs are a hidden headache for home gamers. The GC PRO Renewal features unique 'hollow-design casters' with open centers. Come to think of it, most wheeled chairs have solid wheel centers. The open-center design captures two birds with one stone, delivering functional performance alongside a sleek, stylish aesthetic.

These unique casters not only create a futuristic look but also use smooth yet durable urethane material to minimize floor damage while rolling fluidly. In particular, while seated and stationary, they hold the chair firmly in place, yet glide smoothly without friction as soon as you push to move—a feature that proved very satisfying.

Standing at 181 cm and weighing 86 kg, I have a somewhat larger build, but even by my standards, 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 fixes even the subtle discomforts gamers face in-game.

On top of that, offering a 15-year free warranty demonstrates SIDIZ's overwhelming confidence in product durability. The fact that a 15-year warranty policy—rare even in general office furniture—has been introduced for a gaming chair makes it well worth purchasing on its own. Coupled with detailed cooling and tilting options and unique design accents, 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 embodies SIDIZ's philosophy and proprietary ergonomic research. A national team gaming chair created for esports pros who refuse to compromise on even the smallest detail for victory, as well as users who spend most of their day in a chair. Wishing the esports national team great performance and success at the upcoming 2026 Nagoya Asian Games, I conclude this review of the GC PRO Renewal.
