The ThunderX3 XTC is a mesh-backed ergonomic gaming chair built around a SYNC5 multi-adjustable mechanism, combining synchronous tilt with multiple lockable recline angles so the chair can be fixed upright for focused work or reclined for a break. It has 3-directional lockable armrests, a 2-directional adjustable headrest, and an adjustable-height seat, all supported by a safety-rated gas lift. Overall height is around 126cm with an 82cm backrest and a 53cm-wide, 57cm-deep seat cushion, rated to a 125kg maximum user weight with a chair weight of roughly 24.5-26.5kg depending on configuration. Well suited to long gaming or work sessions where breathable mesh and real recline/lock adjustability matter more than a leather look. Ships flat-packed -- seat, backrest, base, gas lift, casters and armrests arrive separately with the hardware and instructions needed for home assembly, typically a 20-30 minute build for one person.
