The ThunderX3 XTC PRO is the upgraded version of ThunderX3's mesh-backed XTC chair, keeping the same SYNC5 multi-adjustable mechanism (synchronous tilt plus multi-angle lock) and adding a more refined mesh weave and padding over the standard XTC. It has 3-directional lockable armrests, a 2-directional adjustable headrest, and an adjustable-height seat on 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. Aimed at gamers and remote workers who want the XTC's breathable mesh and lockable-recline adjustability with a step up in cushioning and finish. Ships flat-packed -- seat, backrest, base, gas lift, casters and armrests arrive separately with the hardware and instructions for home assembly, typically a 20-30 minute one-person build.
