The ThunderX3 SOLO 360 in this Mesh Black finish is the breathable-mesh-backrest version of ThunderX3's SOLO 360 ergonomic chair, built around the same SYNC4 synchronous-tilt mechanism that reclines the backrest and seat together, plus fully 360-degree rotating, height- and width-adjustable armrests. The mesh back is the better pick over the PU/leatherette Modern Black variant for hot climates or long sessions where breathability matters more than a leather look. A Class-4 BIFMA-tested gas lift handles height adjustment safely over years of daily use, and the chair is recommended for users roughly 155-195cm tall, rated to a 125kg maximum load, with a net chair weight of about 24.5kg. Intended for extended desk use -- gaming, remote work, a home office -- where all-day back and shoulder support matters. Ships flat-packed with the seat, backrest, base, gas lift, casters and armrests separate, plus the hardware and instructions needed for home assembly.
