Recline resistance can feel different depending on the sitter's build; try GX at an Australian stockist where practical. The gas-lift column now has a black finish because a heat-treatment process is used to improve durability.
GX is an ergonomic gaming chair for people who know the value of experience and balance immersion with ease, work with rest, and familiar routines with new possibilities.
Move the wide headrest up or down, then set its angle so support follows your posture through focused work, play and a quiet reset.
Different mesh tension across the backrest balances flexibility through the shoulders with steadier support through the lower back.
BUILT FOR MORE THAN PLAY
GX is for people whose desk changes purpose across the day. It brings precise adjustment, breathable support and a calmer design to work, study, gaming and downtime.
The current pre-order dispatch estimate is shown beside the purchase button and will also appear in your cart.
FOR FOCUS
Set GX upright, bring the armrests to desk height and use the dual-tension backrest to stay supported while typing, reading or creating.
FOR PLAY
Four recline stops and adjustable tilt resistance let you move from concentrated play to a more relaxed posture without changing chairs.
FOR EVERYDAY ROOMS
GX keeps the strong adjustment range of a gaming chair in a clean SIDIZ silhouette that sits comfortably in a study, bedroom or shared living space.
GOOD TO KNOW
If you prefer a task chair without a headrest or want a different support profile, compare GX with the wider SIDIZ range before deciding.
GX combines three support surfaces so the chair can feel composed when you are upright and welcoming when it is time to recline.
A more flexible upper zone lets the shoulders move, while the denser lower zone provides firmer support where long sessions tend to feel demanding.
Height and angle adjustment bring the broad mesh surface to you, helping the head settle naturally when you lean back.
Dense moulded foam spreads support across the seat while retaining a resilient feel through longer work or gaming sessions.
Change pace without leaving the chair. GX lets you hold an upright angle for close work, then open the backrest when the session calls for a pause.
Choose from four stop positions, from a focused upright posture to an approximately 120-degree recline.
Set how readily the chair moves with you so the return from recline feels controlled for your build and preference.
Small changes at the arms can make a desk setup feel more natural. GX gives you fine control over height and angle for changing tasks.
Bring the pads level with your desk to support the forearms while typing, using a controller or moving between devices.
Turn the pads inward or outward so arm support follows the way your hands meet the keyboard, mouse or controller.
The broad contact area gives your forearms room to settle without making movement feel restricted.
The woven surface reveals different tones as light and viewing angle change, adding personality without an oversized gaming-chair look.
Angled controls sit where the hand can find them, with soft-touch details that make everyday adjustment feel deliberate.
Make precise adjustments for immersive play, then recline when the action slows.
Use the same supportive chair for study, creative work, meetings and gaming.
Chameleon mesh adds character while the restrained frame works with the rest of the room.
GX brings gaming-level adjustment into a clean silhouette suited to shared spaces.
