The ThunderX3 SOLO 360 is an ergonomic gaming/office chair in this Modern Black finish, built around a SYNC4 synchronous-tilt mechanism that lets the backrest and seat recline together rather than independently, for a more natural range of motion during long sessions. Its signature feature is the fully 360-degree rotating, height- and width-adjustable armrest design, alongside a height-adjustable seat and a Class-4 BIFMA-tested gas lift for reliable, safety-rated height adjustment over years of daily use. Recommended for users between roughly 155-195cm tall and rated to a 125kg maximum load, with a net chair weight of about 24.5kg. Intended use is extended desk sessions -- gaming, working from home, or a home office setup -- where all-day lumbar and shoulder support matters more than a purely decorative chair. Ships flat-packed with the seat, backrest, base, gas lift, casters and armrests separate, plus the hardware and instructions needed for home assembly.
